16GB MicroSD - how much will the Class affect performance? - HD2 Accessories

Evening XDA!
So... It's time I upgraded my HD2's capacity. 16GB MicroSD's are now reasonably (ish! @ under £30) priced so that's what I want to go for. Most are Class 2 but I've seen a few Class 6s knocking about too.
Is the speed difference, in reality, a massive issue? Stuff I do that perhaps might require speed:
Watching XviDs in TCPMP
Taking photos
TomTom/iGO
Music
Will I notice much of a difference between the two classes of cards?
Any feedback is much appreciated! Thanks!

u just can compare my
kingston sdhc 8gb class 6
to
sandisk sdhc 16gb class 2
i could figure out a speed advantage of the class 6 about 0.8 mb per sec
my 16gb class 2 got 3.8Mb/sec
my 8 gb class 6 got 4.5Mb/sec
copiing the same file....
if somebody got different rates pls post them there.
i never had any problem with the lower data transfer rate of my 16gb sdhc, smooth vids, instant starting apps, nearly same "short" install time for apps
Ps.: i was copiing a 7xx Mb video file to my HD2 in HDD mode

I have a class 2 16gb in my HD2 - I've had no problems with the speed.
watching AVI files with coreplayer is always smooth, tomtom loads up in about 3-4 seconds.
Remember the read speed is a lot higher than the write speed.

Generally you are going to be OK with a lower class. There are however certain things that a lower class memory card will limit, like HD video playback or a high speed game installed on the card (I think Asphalt is a good example of this).
You have to decide what your going to be using the card for and adjust how much you are expecting to spend accordingly.
Be aware that if you are going for a reputable brand then buy from a reputable site. Buying a Kingston or Sandisk from Ebay for a knock down price may mean you getting a cheap knock off. Tread carefully, and give this article a good read, give you a better idea of how easy it is to buy a knock-off card.

Hope this helps

I have been wondering the same because I have been debating on buying the new Kingston Class 10 16GB MicroSDHC card but if the HD2 can't fully utilize the speed, I will probably splurge for the SanDisk 32GB MicroSDHC card and get rid of a few of my 16GB MicroSDHC cards. It is kinda a hassle to carry around a card full of movies, card full of music, and a card full of pictures so I would love to get a 32GB when the price comes down a little more.

Anyone know any reputable sites??? I'm in Australia... So hard to find one to ship Australia and cheap!
I'm after the Kingston 16GB Class 10 card!!!

Thanks a lot for the tip guys. I'll definitely have to have a think about whether I'll need the extra speed, of the top off my head I don't think so but there's a good chance I'll be slapping a few PSX ISO's on the SD card in the future which I guess might be a factor!
@above - unsure of Aus sites, but stay away from ebay as another poster said. 99% of stuff from China (and a lot of the stuff local too) is cheap, low capacity memory hacked to appear to be 16GB and often enough they even include viruses on the damn things too!
UK buyers - Play.com are doing Class2 16GB's for £28 delivered (+Quidco cashback, www.quidco.com)

the only place in oz i could find a 16gb card for my hd2 was vodafone. it wasn't cheap ($89aud) but i've not had any issues with it. it says it's a class 2. i'm sure i read here on the forum that the class really isn't an issue with the hd2 anyway.

Umart sell the Kingston 16GB Class 2 Micro SD for $55. Unfortunately it's the only one they sell (no class 6 available on the website). Have purchased several times from them with no issues.

I did not even know there was a difference in classes. Glad I read this thread.

Class 10 SD cards
Anything over class 2 (which means it can read at a minimum or 2Mb sec) will be a waste of money on a mobile phone. Class 4 and up to the latest class 10, are designed for the speed needed on high end digital cameras that shoot HD videos.
Save your money, buy a good quality, genuine class 2 card, you will not see any difference on an HD2 with a class 10 card in it.

Some users reported that after changing their bundled class 2 card with class 6, music, album etc are up to 3 times faster in loading.
I just ordered a class 6 card to change it with mine class 2, will report about it.

Class
Im using the 16 gb kingston class 2 and it works like a sharm... if you are really picky you can go with a higher class card but be prepared to add some extra cash for a tiny bit of quicker preformance
Just so you will understand how the cards are built there is not much diference amongst the classes. This cards all have 16 Gb space whitch cover the tiny sd card. the diference is that on the higher class cards, the bytes will be shared out in a much more constructive way so it makes it easyer for the phone to read the data. we talk up to 2 seconds faster from the lowest class card to the highest class card. I belive thats from class 2 to class 6.
Good luck with your choice

32GB microsd cards coming soon?

Since I've bought my Omnia II I've been looking forward to getting a 32GB microsd card which the device claims to support. Only problem is that they don't exist yet and I can't find any information on when I can expect them to be in the market, or how much i'll be expected to shell out for one.
Anyone else holding out for a 32GB card? 16GB is a lot, but not nearly enough to hold all my music, let alone having room left for taking photo's/videos.
hopefully in a few months ,according to this http://www.engadget.com/2010/01/13/samsung-announces-64gb-movinand-flash-32gb-microsd-card/
I wouldn't hold out for anything...

The new crop of microSD cards are getting ridiculous storage capacities for something this small - step back 16GB microSD cards, the 32GB cards are coming to town. SanDisk just might be the first to release microSD cards of this capacity.
By the way, this is the Swan song of microSDHC - they are capped at 32GB capacity. Coming to replace them will be the microSDXC variety (XC stands for "extended capacity").
Getting back on topic, SanDisk will release the world's first 32GB microSD cards next month and their price is expected to be 200 US dollars (150 euro), which obviously includes he early adopter's fee and the bragging rights that come with it.
We're joking of course, but 16GB microSD cards from SanDisk can be had for as low as 40 bucks - buying a phone with a hot-swappable card slot sounds like a good idea, doesn't it?
But if you absolutely must have one, you'd need 200 dollars by next month when these cards start shipping.
Source 200$?? LOL,,LET OBAMA PAY FOR EVERYONE OF THEM

I'm using SunDisc 32 Gb class 2 without any problem. It is not very good for watching films from it because 2 class (slow for film streaming with high bitrate), but for data, photo and music it is very nice. I copy film from card in to internal (8 Gb) memory and watch it.

Not all micro SD class 10 have the same speed my friend.
class 10 card means that meets the minimum requirements of class 10 of SD Card Association protype, which is 10 MB/second
in fact some quality class 6 cards may give you speed more than 10 MB/s, while cheap - low quality class 10 will give you just 10 MB/s or even worse theoretically 10MB/s under perfect weather ect condintions.....
par example samsung sd class 10 plus gives you up to these
• Speed Rating Speed (read) : 24MB/s
• Speed (write) : 21MB/s
which i think worth the few extra usd.
same brand's class 6 cards give you
Speed (Read) 17MB / sec.
Speed (Write) 12 ~ 13MB / sec.
which is much faster than low quality class 10
So you should rethink about class 10 now
Yeah i agree.
My Class 6 Sandisk transfers at 10MB/s beating my Class 6 32GB Gskill transferring at 6 MB/s max.

MicroSDHC 32GB C2 or 16GB C10?

I was thinking about upgrading from my current Sandisk 16GB c2. As many of you know Sandisk is out with there 32GB c2 MicroSDHC which is selling for $100 by Verizon. But if you look on ebay you can also find other 32gb c2/c4 MicroSDHC from TopRAM and Centon. Now I personally have never heard any of these company so I am very spectacle.
Now my question is which would you go with 32GB c2 or 16GB class c6/c10? To me its storage vs transfer rate.
1) Sandisk 32GB MicroSDHC Class 2 = $100
2) Kingston 16GB MicroSDHC Class 10 = $135
Clearly you should really been far 16GB storage even as decided to use even go want to do look more like 32GB transfer rate?
FYI 16gb class 10 Kingston is $98.99 over @ newegg and if you look hard enough u can find it around $79
I am not sure what you are saying but some claims that the Sandisk 32GB C2 they get around 5mb/s write. So IDK ATM as Kingston 32GB Class 6 is selling for $700 on ebay WTF? Last time I check they didn't even have 32GB class 2, could be fake who knows.

I am aware of that as they been had it for sometimes now but I was more leading to 32GB but who knows if I do decide to go with 16GB I might go with C10 from Kingston.
But has anyone tried TopRAM 32GB Class 4 or Centon 32GB Class 4? If so is it thoughly tested via R/W IOPs and fully chunking the card.

You cant go wrong with ScanDisk
its a safe bet
ilordvader could you test the R/W speed of your card and post back.
So after searching and reading many threads in various forums I came to the conclusion that even class 6 is an overkill so class 10 is out of the question other than bragging rights.
Now has anyone used Transcend or A-Data? they seem to be selling at Newegg so they can't be questionable unknown like TopRAM or Centon which I never even heard of until I was searching for MicroSDHC.
Anyone recommend any 16GB class 6 cards? I am still unsure on not ordering SanDisk 32GB Class 2 as storage is high but the speed is low. As majority of user who running Android port do recommend getting anything over class 2.
Extreme candidates:
Sandisk 32GB MicroSDHC Class 2 - $100 < Storage
Kingston 16GB MicroSDHC Class 10 - $135 < Speed
Are these the only reputable 16GB Class 6 candidates?
A-Data 16GB Class 6 - $53.99
Transcend 16GB Class 6 - $62.99
Lexar 16GB Class 6 - $69.99 < Questionable; produce inferior products
Has anyone heard of these company before?
Centon 16GB Class 6 - $58.99 < Questionable; but listed under Newegg
3C_Pro 16GB Class 6 - $44.99
TOPRAM 16GB Class 6 - $44.99
Team 16GB Class 6 - $44.99
i bought this. Komputerbay 32GB MicroSD SDHC Microsdhc Class 6. £88, which was preety steep.
i get read speads of around 3.5 mb/s and write speeds of 4.5 mb/s, i cant find my 2 speed to compare but it does seem quicker.
though the web site gaurantees minimum 6 mb/s write speeds.
it was amazon so i though it would be ok.
edit.
just tested it again i am getting 6 mb/s read speeds now.
johnwalk did you thoroughly test the card? by formatting and filling it up fully with chunks? if you can confirm its overall performance then I might also order it. Can't wait for other vendors to make it as I need it now. On class 2 card it takes like 30min to just move around 4.5gb now that's way to long for me as I'm always on the go, but thanks for your reply as ill look in to that company.
I don't want to spoil anything, but my HD2 just destroyed my 8GB Sandisk card. 'Luckily' this was not a $100 card, but still.......
Are you shure you want to spent that much, or did you never have your previous card(s) being destroyed?
Wish you goodluck anyway
i just formated it normally the filled it up with music and video still got two gigs left im like a dog with two tails i dont know what to listen to first lol. but the tests i done with it was when it was 28 gigs full only had it two weeks and at first it was slow, especially when you went into the music player it took a few seconds to update but hey a lot of files to browse but its been ok the past few days, but im now at the stage where i dont plug it into my computer anyway i just access my pc and transfer albums by wifi takes about a minute an album, any video usually gets streamed anyway, but wanted a bigger selection when i go on holiday next month.
def recomend this card thougth the first few days i thought i should have gone for the class two, im now happy with it now it all working properly.
I'm at work now and in an hour when I go home ill thoroughly look in to this card and post my finding. As I never even have heard of the company and if I like it ill post feedback here so others can buy it with confidence.
Far as flr goes how did HD2 destroy your card? corrupted the data? or the flash device is unreadable fully? BTW I never needed an flash card before as this is my first smartphone. Also I was welling to spend $750 few months before HD2 was officially deployed in USA. So I'm not worried about $100.
PS: Also have an eye on HD3 as the spec is 90% accurate from my guess after looking at the specs. So let's see what happens as I don't want a device which may have 2 versions, hence EU-Leo512 and EU-Leo1024.
off topic but im seriously looking into the new batch of android tablets which are just coming out now, maybe 7" or 10"

Hope the HD3 is for Att this time
I've got up to 14.7 MB/sec on my 16GB Kingston Class 10.. and my phone works soo smooth now!
Compared android sliding of homepage on my 2GB Class 2 card and my 16GB Class 10 card, and there is some lag with the 2GB card, and none at all (100% realtime) with the 16GB card..
So, personally I'd say; save some exrtra bucks and go for the 16GB Class 10 Kingston one!
@HyperNode
There are several threads here regarding SD cards being destroyed, or whatever description is given to it.
From one moment to another you get the message that you're card has to be formatted. If you accept it, it says something like (only) 30 MB being available, which doesn't get formatted. Your card can no longer be seen by your HD2, nor by your PC or any other cardreader (afaik)
I´ve never had this problem before. It looks like a specific HD2 problem.
Either with or without a combination to a specific brand or card.
I'm very curious about your experiences.
Please keep us updated.
Thanks and goodluck!
Same here. Mythen hd 2 just destroyed my SD card des SYstem ago
It happened already bevor, Thatcher i couldn't See Thema data anymore , but nie i Cantel even Format it anymore

32gb class 2 vs class 4

Hey guys,
I'm interested in getting a 32gb card. I will be watching movies off it and just basically reading books. Is there a huge diff between the two? I googled and I found the diff write and read speeds but my question is how relevant is it to the user? Like will the movies be choppier or books open slower? etc

Sadly, to throw a wrench in your question, there is authority behind the class markings. Basically, there is nothing stoping makers for marking a card Class 10, even when it can barely do 1MB/s writes. So, how does that answer your question?
It comes down to brand. Sandisk by far makes the best microSD cards, which almost always outperform their rating. I have an 8Gb Class 2, that constantly benches at 5MB/s sustained write, and 12MB/s sustained read. I also have an 8GB Kingston clas4, that can barely hold 2MB/s write, if it is lucky. The other issue few talk about is random reads, where again, the Sandisk is much faster (and random reads are not part of the class specifications)..
So, if you get a decent brand (again, Sandisk), a class 2 should be suitable for all music, and most movies. If you can afford it, class 4 will give you wiggle room.
How about adata? Have you had any experience with them?

personal experience no, but i haven't heard alot bad (actually, better than Kingston in many cases). I know they have decent prices on their cards.
With what i was saying before, it is fair to mention that while slow, my Kingston does still work. But saving things to it was painful, and so i avoid its use. Even if you don't get the fastest card, i think the biggest pain will be filling it once.. after that, using it should be ok..
I see. What about the performance? Saving stuff to it isnt much of an issue to me I think. Im more concerned on the performance. Like running movies off it and launching programs etc the sandisk sounds awesome but the price is much higher
For the use you are planning(movies) the big factor will be sequential read speeds. The class system is too easy for the manufacturers to game. Check the specs for the card you are looking at...if they don't tell you, it's likely because they suck. Sandisk class 2 cards are, as stated, usually better than the class 2 they are rated.
so you guys would recommend a class 2 32gb sandisk over a class 4 adata card of the same size yeah?
Can't really say one way or the other. From reading reviews at Newegg...seems like Adata tech support might be a bit iffy...then again those reviews are usually posted by those who have issues or feel like they have to defend their purchase(ie...fanboi's).
One thing I can see for myself...Adata is the only manufacturer on Newegg to actually list their full specs. Even on the manufacturers pages...only Adata has manned up and posted specs. otherwise they all just fall back on the SDHC specifications for class...which as stated can be gamed a bit.
At the end of it all..it's your cash...spend it the way you feel like...do some research for yourself first.
I have a scandisk class 4 32GB and it is way slower then a smaller class 6 that I have. For me, I don't think I could stomach anything slower then the class 4 for large files.

Sandisk is great. I was originally running Nookie Froyo from a class 2 Sandisk. It was actually pretty solid. I moved up to a Transcend class 6 and it's been good too. Both seem to perform well over their class specification when I'm transferring files and have been very stable.
On the other hand, my friend has a Kingston class 10 which seems pretty buggy. A lot of force close errors, looping boots, etc. Though these could just be a coincidence. Haven't seen him transfer any files though, so I can't judge the speed.
SD Cards..
You should be aware that Sandisk, Adata and others do not actually manufacture flash memory chips, they mostly package and test it - the big boys in the game are Intel, Samsung, Toshiba and Hynix. Depending on where or from whom Sandisk buys the basic chip the specs may be different.

Actually there is a requirement if you're in the SD Association. But in reality anyone can stamp a C10 on a card, especially no-name brands.

Absolutely. AData are junk in my experience.
Kingston and SanDisc are the only ones that are reliable for all devices that I've owned. Others are hit and miss, PARTICULARLY Patriot. I've had 3 Patriot cards that were JUNK in most devices. I had two Patriot SD cards for a camera that were fine but couldn't work right in anything else, and I (stupidly) purchased an 8G uSD card a few years ago for a phone and it was junk there, and I've periodically tried it in new devices for giggles and it's been junk in every single one.
I'll bet a SanDisc C4 out classes any other brand C10 in device like a phone or tablet.
Side note: All 3 Patriot's work just fine on my computer. I did tests particuarlly on the 8G uSD over and over and over and it was fast and reliable in my card reader. Every device locks up or goes slow as hell if it's in 'em. My guess is that they didn't follow specs closely.
So a Sandisk Class 4, 8GB would be a good pick?

SD cards are a complicated topic... not to throw another wrench into the system but you also want to be careful WHERE you buy your card. SanDisk counterfeiting is RAMPANT since a vendor can take a blank card, less than a pennies worth of ink and then charge you some percentage of the SanDisk price while still reaping a huge profit. As unfortunate as it is, real SanDisk cards always seem to just work while the other cheaper cards can be hit or miss. Honestly though the only real problem with off brand cards and the NC I have had is that they don't always boot so good. So I use my SanDisk 8GB C2 (bought from Costco) to boot and my Patriot 16GB C10 to watch movies and store stuff. Buying from Retail, Newegg, or Amazon (Amazon itself, not a sold through vendor on Amazon) should help make sure whatever you buy is the real thing. Good Luck!

[Q] Minimum micro SD class for the galaxy note

Hi guys, I am about to purchase my galaxy note next week and I was wondering if anyone could shed some light into the matter..
Which class of micro sd card should I buy? (minimum) I was hoping to get a 64gb but if that would underperform, there would not be much of a sense to it.
The maximum reading/writing I will be doing in the note is probably playing 1080p playback + mirroring it to the tv. maybe some hi definition video recording as well straight to the memory card.. but most often than not, I would play a 720p mkv movie.
Would a class 4 suffice? Any suggestions on which brands I should look at / stay away from?
Class 4 of any decent brand should suffice.
Class 2 cards from Sandisk will also suffice (their read/write speeds are enough for 1080p encoding and decoding). May be a hassle if you regularly transfer a lot of data to and from the card since thats the time when the slower R/W speeds will come into play.
Why get anything less than class 10? If you can afford a Note, you should be able to spare another $20 for a fast sdcard...
class 10 cards can cost upwards of $80 for an 8gig card.

i picked up my class 10 a-ram 32gb microsd for $49.95AU + shipping.
it really depends on what you plan to use your note for. if youre filming 1080p video at the default 17mbps, thats about 2mb/s that you'd want minimum for just filming. so any speed should be fine as long as its above class 2. i just prefer faster cards since theyre getting cheaper.

I've read class 10 doesn't always mean fastest read speed or something to that effect. Not always beneficial to get a class 10 since it writes faster but doesn't always means it reads faster. Someone else can probably elaborate for me.

A-RAM is the brand. i bench'd it. write speeds are 11mb/s, read speeds are 14mb/s.

I've read class 10 doesn't always mean fastest read speed or something to that effect. Not always beneficial to get a class 10 since it writes faster but doesn't always means it reads faster. Someone else can probably elaborate for me.

normally read speeds of class 10 are still higher than write speeds. but the read speeds dont really vary much between classes. my kingston class 10 reads at 12mb/s, my a-ram class 10 reads at 14mb/s, my sandisk class 2 reads at 10mb/s. so if all you need is read speed, then any card will do.
even class 2 or 4 on Sandisk it will work fine. i believe just buy a good make one ( not a fake from China ) , but i bought mine Lexar class 10 and work great , i couldnt be happier.

It doesn't necessarily write faster either!
All the class indicates is the minimum sustained write speed under optimal (i.e. unfragmented) conditions. It says nothing about the read speed, which is what is generally important in mobile devices since they are usually used for content consumption rather than creation.
As NZtechfreak has already mentioned, Sandisk Class 2 cards almost always well exceed the class minimums - I've been using 16gb Sandisk Class 2 cards in my phones for a long time now, and I've yet to get one that had a write speed less than the Class 6 minimum of 6MB/s, and the read speed has always been 20MB/s or above.

A good read why Class 4 cards are the best ones to use for your smartphone: http://forum.xda-developers.com/showpost.php?p=14456360&postcount=42
I started out with a Kingston Class 2 32GB I had laying around, and then switched to a Class 10 32GB made by PNY that I got from Microcenter for $59.95.
There was a very noticeable difference in photo taking lag and the media scanner, plus app access on the card. Now there is almost no photo lag, from snap to saving. Haven't messed with the video much yet...
I've Samsung class 10 32 gb. It's really good, but my device started rebooting because of it. "System Process has stopped working."
What I found out is that after removing my micro sd my device is a hell FASTER than before!!!
Maybe a faulty micro sd, no since it works fine in my pc and other devices.
I want to check does any of you have the same problem???

Cheap class 4 8gb sd and 16gb class 6.

http://www.ebay.co.uk/itm/251038684911?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
I bought the 8gb for £2.80 yesterday price seems to have risen most likely because people were buying a LOAD of them.
http://www.ebay.co.uk/itm/MicroSD-T...S_Accessories_Software_ET&hash=item3cc384c620
Probably the cheapest prices i have seen.
I would never buy anything like a class 10 card from eBay unless the seller was someone like eBuyer or Argos, so many fake cards on eBay.
Better to pay more and know you are getting class 10. Also the class doesn't mean a hole lot, read and write speeds are what you should look at.

The class of the sd card IS what indicates the read and write speed, a class 10 gives you min 10mb sec write speed.
It's also good to pay attention to the manufacturer. Some no-name class 4 card I got was barely working, while there's no problem with a Kingston one, with the same specs.
Iv been using a genric class 4gb sd card for years and i still get 5mb/s write speed on it.
My class 4 barely manages 4MB/s, usually in the 3s. Sandisk

I got the 8gb sd card in the post, speed test shows at 4.8mb/s write speed.
It happened to me to find micro sd cards not respecting class written on them. there are a lot of softwares that mesure writing and reading speed. Personally, I would spend a little more money for a good product i.e. I have a 32Gb Samsung, Class 10 and I payed it 35€ (shipping included..)
If you don't need a big capability, a good 8gb or 16gb can cost you not more than 10-15€...
It's something you buy once and least for year..buy it good and you won't regret it!
