micro SD speed Class 2 and Class 4 - Mogul, XV6800 Accessories

I have the latest ROM 2.17 intalled on my Sprint Mogul. I am searching for a larger card. I am considering a 4GB card but wanted to know if the speed is factor to consider. My understanding is that class 2 is 2MB/sec while class 4 is 4MB/sec transfer speed. Can the Mogul take advantage of this? Is the speed increase enough to really be noticeable? I am assuming the 512MB card that came with the Mogul is class 2. I cannot find any markings on the card to distingish the class.
Thank you for any help provided.

I know the answer is late...
Hi, don't know if you got an answer to your question or not. I also spent about a good three days trying to track the answer down. I never found it anywhere, called HTC they sent me to Sprint...anyways...the answer that I got was that the Mogul has an average speed of 2Mb/sec; so it may not be necessary to buy a Class 4 or 6 card if it is more expensive. It looks like price for capacity is the only real factor when looking into buying a MicroSD card for the mogul.
If any one can state different (i.e. Mogul able to read/write at a higher rated speed) that would be good to know.

It might really help to have a spare, non-SDHC card in case you need to do a ROM upgrade directly from the microSD card...

Kaiser Memory Card capacity

Some people say Kaiser can manage up to 8GB and some say it can manage
up to 16GB all I have is 4GB and its more then enough. But a friend wants to send me one and asked me what is would prefer. I would go for 16GB but I don't know if I can use it. I have a AT&T Tilt.
Thank You.
Hi and welcome around,
searching a little bit around may have answered your question .
The Kaiser definitely supports µSDHC up to 16 GB. As soon as 32 GB comes up, it will also support it.
Got a 16Gb in mine. Runs great. Just got to find stuff to fill it now!
What 16 GB are you using?

I also have a 16 gb micro sdhc card - got it a couple of weeks ago. It's a sandisk, and works great. I've had no problem whatsoever getting more than half filled already!

I am also using a 16GB sandisk. It works great and have no problems. The only thing I will say, as with any flash memory, is that mine is just below 15GB. I personally think that the labeled amount should be the minimum amount available. Sorry for that... go for the 16GB!
Where are you guys buying these 16GB cards? I can't even find them on any of the major retailers' sites. I'm curious to see how much they run. 16Gb used to be a pipe dream to me. heck, the 4 gig I'm currently using used to be such a pipe dream. I remember when I paid $350 for a 1 gig SD card...
16 gigs would be lovely though. I could load up on music.

Here are 2 threads dicussing where to find them: here and here.
I got my 16 gb sandisk card on ebay, for $52.00 delivered. I've bought a number of accessories for my tilt off ebay. It's a good place to buy things, as long as you buy from a seller with a really good feedback rating.

16GB MicroSDHC Class 6 card (DRATS!) - ONLY $24.99 (s&h FREE)
The best bang for your buck right now for a Class 6 MicroSDHC card, is the 16GB made by ADATA - from Newegg.com:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820211300
- - -
What SPEED is the Tilt able to handle for the MicroSDHC cards? There are Class 2, 4, and 6 - Class 6 being the fastest. However, if the Tilt is only able to transfer up to or slightly below the speed of a Class 4 card, then buying a Class 6 rather than a Class 4 would be a total waste of money for the higher speed -
- - -
I was going to post something about the ADATA 8GB card I actually have, because I thought it was a great buy at 18.99, but when I checked their web site today, it turns out since I bought mine only about 2 weeks ago, they posted the above Class 6 speed card with 16GB!
I would make a fuss and return my old one, the only thing is, I don't even have any way of filling up the 8GB card - so I may as well wait until the 32Gb cards come out - also anothjer reason is my Tilt is getting to bee a little long in the tooth with scratches, etc. - so by the time the 32GB cards come down in price there may be other models coming onto the market I want to buy instead of the current phone I have now...

There will no doubt be better phones on the market in the near future (HTC's leaked road map has some nice looking phones due out this year, and that Nvidia Tegra system looks awesome). But, the beauty of the situation here is, pretty much any phone worth buying in the future should have a micro SD slot. It kind of sucked buying SD cards with Mini SD on the horizon, and then buying Mini SD cards with Micro SD on the horizon. But Micro SD seems to have settled in as the standard, so your 16 gig card will probably work on your next device.
According to A-Data's website, they don't make a 16gb microsd card
The link above takes you to a 16gb flash card, but it's not a microsd card. The cheapest ones I've seen are 50+ on ebay, probably fakes, but I have an 8gb, probably fake that I go on ebay, and it works perfectly.
I have a 16 gb micro sd card that I bought on ebay, and it works great. I've had no problems whatsoever with it, and I've really loaded it up! I paid $52.00 for it (shipping included).
It Supports up to 32gb
Correction 16GB MicrSDHC not yet available?
My first post tothis thread was wrong, that was a 16GB sd card, not a micro sdhc card. All I can find for highest capacity (class 6) is an 8GB card which I am now using (and itis fast):
http://www.newegg.com/Product/Product.aspx?Item=N82E16820211341
And it's only $15.49!
It appears that the class 4 and class 6 make little difference in speed tests,maybe the tilt read/write throughput gets maxed out at the class 4 speed??? Any thoughts anyone?

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

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

kaiser microSD card read/write speed

The company I'm working for gave me an HTC Kaiser as work phone. I had a 2gb microSD card as spare, so Im using it for now. What I'm wondering is the phone's read/write speed.
I am considering to buy a 16gb class 6 microSDHC card, would that be an overkill? (not the size of course, Im going to put a lot music etc, but would class 2 or 4 be enough for it? Also, I liked this phone, but just loved HD2(some use LEO, too. I wonder why HTC uses just too many aliases, anyways). I may buy it, so even a class6 card would be overkill for tytnII, would it be an overkill for hd2, too?
Thanks in advance,

A class 6 is overkill for the Kaiser, but bigger/faster is always better. It is not overkill for the Leo.
Rule of thumb is always buy the biggest/fastest you can afford because you never know what you will be doing with it.
However, remember, if you try to drain a bathtub through a 5 cm hole or you try and drain a lake through a 5 cm hole, the same amount of water will still come out the other side.

Can the HD2 benefit from class 6 SD? Or is it a bottleneck >Class 2?

I ordered a class 6 16gb card to replace the slow-ass class 2 8GB card I had in my HD2.
First of all I couldnt find the format sd tool in my energy rom (1st July) so I had to format the card using vista while the HD2 was connected in disk drive mode. THAT TOOK OVER 1 HOUR.
(Is there a cab file to install the "Format SD Card" tool for the newer energyroms?)
Anyways after formatting (Fat 32, 16KB cluster), I started to copy my 1.4GB sd backup file to the card using the same method as above (disk drive mode)....
My maximum write speed was 2.7MB/sec. Average 2MB/sec.
Class 2 speeds????
After restoring the backup, which took forever, I ran spb benchmark on the card and was gutted to get slightly lower results than the old class 2 I was replacing.
Can the HD2 make use of anything faster than a class 2 card?
Has anyone here tested a class 6 or even 4 card and found good write speeds (~6MB/sec, or ~4MB/sec)?
Does it sound like I have bought a lemon (class 2 labelled as class 6)?
I have spoken to the seller and he is adamant that they ARE genuine class 6. Reckons he tested some of the batch in TrueHD cameras which will not accept <Class6. Seems genuine and some of his feedback states that the cards are Genuine class 6. Which leads me to think that the bottleneck could be the HD2... Does that sound likely?
I'm waiting for a microsd USB reader to arrive so I can test the card outside of the HD2, but Until I can do that... can anyone tell me if a class 6 is wasted in a HD2?
The strange thing is that when browsing photos/wallpapers etc, the thumbnails ARE loading maybe 3x quicker than my old class 2. So I'm pretty confused about this one.
Can anyone shed any light here? Feel free to post benchmark results/screenshots etc.
Thanks in advance.
can anyone PLEASE answer this ^^^?
Is there any point having a class 6 card in the HD2 instead of a class 2 or 4 card?
there is a thread in the accessories section have a gander in there, I no this is Q&A's but lots of talk about mem cards in the accessories section mate
Cheers mate, I'll take a look.
I will move this thread there. I also recently bought a Class 6 card and and have seen a huge improvement in media reading and over all performence.
I get 4-5MB/s both for reads writes with my 16GB class 6 card in disk drive mode.
Thanks zelendel and kilrah.

That is exactly the kind of data I'm looking to compare.
Whith my 'class 6' Im getting just under 3MB/S WRITE and under 6MB/S READ when using the HD2 in disk drive mode.
If I use the card in a USB 2.0 reader I can get around 5.5MB/S Write and ~11-13MB/S read.
Based on this alone would you say my card is a class 6 or not. I'm beginning to think it may be a class 4 re-labelled.
Picture browsing etc is faster with my class 6 but all benchmarks indicate it is identical speed to my genuine Kingston Class 2.
What do you guys reckon, Should I send this card back for a refund???
Well if you're getting 5.5 and over 11MB per second with a card reader then we can safely assume it's class 6. The bottleneck is something to do with the phone, rom, cable or simply the phone doesn't like this particular card etc...
EDIT: Test your class 2 card with the memory card reader and see if you get similar results.

Thank you for helping me clear things up.
Comparing the 'class 6' and the 'class 2' transfer speeds is where I really get confused here.
Transferring a ~700MB .Avi to and from SD using a reader:
Kingston Class 2 8GB:
Read 12.5MB/s
Write 5.4MB/s
Unbranded Class 6 16GB:
Read 12.5MB/s
Write 6MB/s
So, from this, would you say its safe to assume:
1. The class 2 card is a good one, performing at almost class 6 speeds.
2. The class 6 card is 'Genuine' and shouldnt be returned.
3. There is a bottleneck when using the HD2 as a card reader/disk drive. I should be getting more than 2.5mb/s write speeds in this mode.
4? Does 12.5MB/sec sound close to USB 1.1 speeds? could my reader or even USB port (Vista laptop) be another bottleneck?
Once again thank you for helping me make sense of all this.
At least I now know that the 16gb card doesnt really need to be returned.
Can you give me your oppinions on the above?
Well class 2 means you should be getting a minimum 2MB/s speeds and class 6 means you should be getting a minimum 6MB/s.
Seems like you have a very good class 2 card.
More info here
http://en.wikipedia.org/wiki/Secure_Digital
Your class 6 is performing to spec.
Personally I would never buy an unbranded card but that's me. A branded card may perform better than there class rating e.g. Your Kingston brand I've always used Sandisk personally...
I've just managed to drum up enough funds to get myself a HD2 and now looking to upgrade my HCSD card to 16GB. To get the "right" class I tried to find the spec on the SD interface but I cannot find anything and the best data I can find is that I shouldn't waste my money on unbranded devices, I would always buy a SANDISK device for something I relied on! For data and communication!
People seem to get appropriate speeds for the class of device they have, if they are branded and sometimes if unbranded. However, there doesn't seem to be anything better than class 6 results debated or given. Is it a VERY rash assumption that the fastest the HD2 interface can go is Class 6?
Chris
Does this mean its not worth getting 32gb cos its a class2
& theat would make the phone slower cos lot more stuff on it
& will take more loading time & play Videos lagy ?
anyone useing 32gb ?
Thanks
My experience was positive with higher class micro SD.
At first, I used 8GB micro SD bundled with my HD2 and didn't notice improved loading speed. Later, I changed it with higher class one, same 8GB, with same manufacturer, Sandisk. Higher class one has name "Ultra" on it. Now with changed SD, loading became WAY faster. "Wow" I realized the higher speed of CPU of HD2.
My 2 pennies.
NEVER EVER buy unbranded memory cards!
Keep an eye on Sandisk cards only and even prefer them to Transcend and Kingston.

[Q] Any Recommendations for Best microSD for Webtop2sd use?

Any Recommendations for Best microSD for webtop2sd use?
I am getting ready to try out webtop2sd on my Bionic but I want to buy a 32Gb microsd card. I was about to get a class 10 but I have been ready there may be some problems with them in the phone. (?poor random access times vs. sequential transfer speeds?)
So, I am not sure whether to go with class 10, 6 or if just a Sandisk class 4 would be best. (I don't really want to spend a huge amount of money either - looking for best performance for a reasonable price)
If anyone has experience using webtop2sd, or is extremely knowledgeable about microSD media, and could recommend the best microSD card to use I would appreciate it. Thanks!
Have you considered just using a flash drive for additional storage? It seems like it would be a cheaper way to go.
http://forum.xda-developers.com/showthread.php?t=1273852 Here's another thread that is talking about SD cards.
Basically if you go with a 32gb Class 10 Micro SD you will have the fastest transfer rates you can get. They are about i think 3 times as much as the class 4. The class 4's work fine though. I haven't really done or seen any bench marking for the Bionic about it. That is what I am planning to get though for webtop2sd for myself.
http://goo.gl/sEGLC
I figure if I am going to be using it as a a full ubuntu basically, would be nice for the extra transfer/read speeds. /shrug
less then 30 bucks for this one....

Im using one of these from a previous daily sale from the same site and it works great for everything. Webtop2sd included. And you can't beat the price!!
class 10 all the way. you will not be dissapointed. the read and write speeds are awesome. i will never use anything but a class 10 unless they come out with a faster one. the are a little pricy but well worth it
I saw somewhere that the bionic is compatible with sdxc cards which are class 30 and up to 64gb. Hellaciously expensive though. Might be worth looking into though.
I'm a bit curious about that, if you find anything out definitively shoot me a message.
I used a class 4 at first, ran AnTuTu and saw other people's droid's beating mine. Switched to a class 10 and I'm holding the top score right now by 5 points (5171, closest 5166), lol, not much but good. It was a big improvement over the class 4. With a class 4 card it was scoring in the high 4000's. The read/write speed is a huge leap, you'll notice if you do any full memory card backups / transfer a lot of music / files to the Droid.
I say look for a deal, I used 2 reward zone coupons at Best Buy to make it free for me.
You can usually find really good deals online or MicroCenter has good prices in store if you don't shop online.

Hmmm, Im using the 32gb sd card from my Thunderbolt, and I got a score of 5120. write speed of 8.4mb/sec and read of 15.5.
is there any difference in the brands? Im always leery of brands of have never heard of, and am thinking about spending more for the sandisk or kingston.
I have been using a Samsung 32Gb Class 10 card for about a month and it works great. Speeds are fantastic. Picked it up at Fry's for $50. I have not used Webtop2sd however.
You should check it out. A full linux distro running on your bionic is pretty impressive.
+1 for class 10, you cant go back once you've seen your card reader hit 17Mbps write speed. i dont even MIND doing superfluous nandroids anymore lol.
