SD Card Limitations - BLU R1 HD Questions & Answers

Has anyone tried anything larger than a 64GB card in their R1 HD? I just popped in a PNY Elite 64 UHS 1 card, seems decent enough speed wise, but was wondering if down the line I wanted to go bigger if there would be sn issue?? I know officially BLU says 64GB, was just wandering if that was as high as they tested, or if a limitation of the Mediatek SoC?

I put in a PNY Elite 128gb card in mine. It formatted to 117gb however failed shortly after. I tried copying music from my internal storage to the external storage and it froze 2 albums in and stopped reading. I'm not sure if it was a dud card or if it has to do with some sort of limitations.
Here is a post of someone claiming to have a 200gb card working though. So there is hope!

Edit - Nevermind, I had a bad card. Can confirm 128gb cards work!

I was going to pick up the 128 card while at Microcenter yesterday, but didn't want to chance it. So I figured ehh 64GB is plenty, then i started second guessing if I should have spent and extra 20$ for the UHS 3 samsung card, but figured with a budget phone would I be wasting $. The PNY Elite seems snappy enough, haven't noticed any noticeable slow down, other than 4 apps not liking being stored on SD

Actually I just got my new SD card from Amazon and I can confirm 128gb cards do in fact work. I must have gotten a DOA card.

I can confirm both a Samsung 128GB EVO Class 10 Micro SDXC Card
and a Patriot LX Series 200GB High Speed Micro SDXC Class 10 UHS-I
Both work in the BLU R1 HD 16GB 2GB Ram amazon variant after I removed ads and installed TWRP. (I would think it would work prior to this also but I never tried it prior).
The BLU device also lets you format the Micro SD card as "Shared internal memory" without any issues like other manufacturers and haven't had any issue installing movies on the Micro SD card for later viewing.
And Mircast works great on the BLU R1 HD also...just with the R1 HD supported 5GHZ wifi(but for the price I can deal)

Ok, I'm satisfied so far with performance of the PNY Elite 64GB (class 10 UHS1). I do notice write times are a bit slower when updating or installing apps, or doing TWRP backups. Thinking of ordering a UHS 3 card to see if it speeds anything up. It's not super crucial, it's still snappy, it's just one of those nagging what ifs -_-. If anybody has any experience with one of the faster SD cards let me know. Are there any read/write test apps where I can measure the actual throughput on the R1??

Memory card advice wanted

Hi,
I've just received my TyTn II and am interested in getting a memory card for it.
It takes Micro SD but what is the max size that it/WM6 will work with?
Also, what is Micro SDHC? and can I use it?
I've seen a 2GB MicroSD card for £7.55 del. but I probably want a bigger card.
I intend using it for tomtom - photos - some games and apps and of course data file storage.
TIA
Bryan
I picked up a SanDisk 8GB via Amazon for under $70 USD (minus shipping).
http://www.amazon.com/Sandisk-Micro...1?ie=UTF8&s=electronics&qid=1204123335&sr=8-1
I have a San Disk 8gig in mine and it's great.
Cheers, Paul
Thanks for the quick replies,
As you are using 8GB cards they must be MicroSDHC? AFAIK MicroSD cards that hold 4GB or greater are all MicroSDHC.
Any chance you can pop your card and see?
The 8Gb SanDisk that I ordered is MicroSDHC (a.k.a. 2.0).
The HC stands for High Capacity and it is indeed for cards above 4 GB.
The device for the memory card has to be HC capable and lucky for us, our Kaiser is
Every micro sd card also has a class (2, 4 or 6 I believe). The higher the number, the better transfer rates (and response time), but also the bigger the cost.
I currently have a 6 GB (class 4) micro SD card. I'm going to wait a while to buy a new one until cards with about 16 GB or 32 GB (or something like that) of memory come around.
I'm also running the sandisk 8gb SDHC card. Its speedy and
works flawlessly. I got it on amazon for about 80 USD
The only thing i could recommend after having a card this big
is a good card exporting program on your phone so not
limited by activesync
Thanks for the help.
The 2GB MicroSD card at £7.55 seems very good value but I'll wait for an 8GB MicroSDHC deal to come along.
Hopefully a faster variant too..
Is it possible to connect the phone to a PC and have it recognised as a large memory stick? I know some phones do and then you can just explore them like a disc drive.
I will setup activesync at home for normal installation etc. but wondered if I could access the SD card whilst in phone from the PC/USB a la memory stick whilst at work.
yes, you can access the SD card like it's a memory stick by exploring. However, the transfer rate isn't as good as a USB connection with a stick. The 8GB SanDisk comes with a USB reader so that the card can actually be used in the reader just like a stick. Fastest transfer rate I've ever gotten with my phone
I'm using an 8Gb SanDisk MicroSDHC.
Works great!
I have a 8gb and it is fine.. but if you wait until next month you can pick up a 12gb and really have some storage space.

Talk about a deal i just purchased two 8gb for $70 because they were used and only came with one adapter.
I got my 8 gb sandisk sdhc card on ebay - another place to look for a great deal. Just be careful about the track record of the seller. I love the 8 gb card, but will be looking for a 16 gb card when they come out.
i saw the 16GB ones out anyone tried if it will work with the kaiser???
I run a Kingston 8GB SDHC in mine without problems (brought it over from my SDHC enabled Orbit), which I bought for £25 about 8 months ago from mobymemory. Never had any problems with it at all.

Wintec Class 10 microSDHC 16GB Card - $29.49

Saw this card on Newegg today. Pretty cheap for a Class 10 16GB card and reviewers state it meets Class 10 standards, and that it appears to be a rebranded Samsung card, so it is a quality product.
Android only supports Class 6, meaning this card should be plenty quick, and will utilize full Class 10 potential during file transfers over USB.

3 speed tests so far in CM7: 6MB/s Write 14MB/s Read average. Bought it at Frys for 32.
Works AMAZING
I bouth this card from newegg and ive been using it about a week now and it works great not a snag at all
Anybody got a good report on this? I wanna buy it but I see a few reviews saying it works for a week then dies... can anyone vouch for this card being solid?

Wintec 16gb CL10
Just got the Wintec 16gb CL10 from Newegg, put it in my Sprint Hero to format and as soon as it finish saying setting SD card the screen locked up. removed battery/ installed and saw installed apps icons were gone in its places gear icon. Installed original 8gb and app icons were back but apps came up with FC. removed each app and reinstalled and they work fine now. I'm afraid to put the 16gb back in, it seems fine in my laptop. I have no idea whats wrong!
I got one of these around Christmas. Formatted, partitioned and transferred my stuff. I thought all was well until I had to restore a nandroid and it bootlooped. I put my old 8G Sandisk back in and haven't tried again. So my experience was it worked about a week. I guess it's a write/read issue. I had trouble with recovery mounting the card to even see my backups. I had read reviews of spotty quality and I guess I had the bad luck of the draw.
hmmm ok then I guess i'll pass on this one. I want to get one that'll last so i can transfer it to a new phone when i upgrade.
on htc website, it says microSD 2.0 compatable, & i know some phones can only support so much extra storage, ie: some say microSD up to 16gb, so maybe the hero doesnt support high capasity cards.
anybody got a conformation on how big a microsd card we can go, that wont cause issues.
i was looking @ this card in the OP, but now im double thinking.

If you mean the 32gb your gonna have to search cuz I've seen very few. Don't remember what brand,most that are 32 gb I've seen are class2. I have a class 10 8gb here and it runs slower in my phone than my class 6 does.Sorry I can't give you more info.My class 10 is a Patriot
I bought the wintech 16 gig card back in january and 15 days later I woke up and my phone said the sd card was not formatted. Both windows 7 and ubuntu 10.10 only saw the card as 1 gig but neither could format it nor create new partition tables. I lost all the data but luckily had a semi recent backup on my computer. RMA'ed it back to newegg and got a 16 gig class 6 card from a more reliable manufacturer.

Maximum storage card capacity

Hi,
I want to buy a micro SD : I have seen that the maximum storage for micro sd was of 16 GB.
Someone has already tested a 32 GB storage card?
If yes, Does it work correctly?
Thanks for your answer.
it's works i don't now how becouse i just test my friends card.
Sorry for my English
Maybe it's was on android 1.6 (max 16), but 2.1 should be supported with 32GB
well, i got my X8 only a week ago, it's my first smartphone.
seriously, what do you guys want to store with 32GB card?
i can't imagine what to store in such space, i figure one could make a portable toilet out of it and still got some more space.
Movies (avi, wmv, etc). HD photos from professional photocameras, hi fi music like wav. Download a lot of stuff with torrent client and else. 32 GB really need for me.

Question was not what I do with all that storage.
Is it possible to have 32GB card in X8 I think that it support up to 16GB ??
I couldn't tell you, because I've bought an 16GB card (class10).
With the price of a 32 GB microSD, I could not fool me.
I think that 32GB is more money then the Phone
You are able to mount 32GB card I've just checked it out but the results are horrible - 500 MB of freshly copied music on the card, and now it is showed as "damaged" on the notification bar. I wouldn't recommend it to you.

I think the X8 will also work extrem slow with a sd card of 16 or 32gb
And with 32Gb class10? The read/write speed is biggest?
I believe that is not a question of card's speed, but more of device's ability to comprehend such a huge space. Just like with enormous hard drives in older computers.
ok.. maybe this out of topic..
what brand of SD card with class 6 or 10??
n where to buy??
im just unable to find it in my country.
in my opinion, 32gb can be handle with very well if this SD card are good.
i mean good SDHC
i found it in my country, designed for camcorder and etc..
but price also different
i just want 8gb with class 10..
currently i have 8gb, no class
my quadrant almost same with droid x, so i think if i have good SD card i can overlap droid x.
where to buy???
32 gb for a phone is a lot of capacity
Im using 32gb sandisk class 2 memory card in my galaxy s initially when it was 2.1 it was slow. But now after 2.2 update its okay. Only startup and shut down process Will take long time. class doesn't matter on phone it matters only when data is to be transferred from pc to phone . Max transfer speed Will be 2mbps in class 2.

there's a lot of good brand to choose actually, personally i'm using transcend.
what city are you in? in Bandung, you can try BEC. i bought mine from kaskus though, it has almost everything we look for
class.. hmm IMO it's unnecessary to use such a high class card. class 6 (6MB/s) is sufficient enough, because android apps are usually not really big, only 10-12 MB at most so no need for such a large data transfer rate.
Has anyone had good success with the 32Gb card? I dont want to buy one if it's just gonna not work properly.
thanks
Won't work
Chances are, it wouldn't work.
The Xperia X8 currently only supports up to 16GB of memory. If you go higher than that you would experience problems. You might be able to make it work for a few minutes then it might not be able to read the mem card.
Hopefully, in future updates we could use 32GB cards.
I've searched around, no walk-arounds on this yet. If I were you, I'd stick with 16GB. That's a lot of storage!

[Q] SDHC 32 gig class 6

Just got NC for early Father's Day! I luv ma fam!
Everything I been finding here talks about 2,4, or 8 gigs SD cards.
NC says it can use up to 32gig.
Anyone tried this? I figure SDHC 32 G class 6 would work.

Everything I've read states the higher capacity cards don't do well running ROMs. Like you I'm new to the nook so I"m sure someone else with more experience will chime in.
I have a 32 gig card installed right now. Works just fine as a data card.
If you want to run custom ROMS off the card, make sure its a sandisk. That flapping sound about larger sized card being bad for Roms is a buncha crap in my opinion (and I have the benchmarks on this card to prove it), but the BRAND of card makes a huge difference when running Roms. Avoid transcend and PNY like the plague.
That said, if you just want the card for data, then yes, the NC can handle them just fine.

What size Sandisk card do you recommend for running custom ROMs? I've read 8 but I really would like to run a 16.
With a sandisk, I can't see any reason why a 16 or even 32 gig card would give you trouble on roms.
Using the card to run your "operating system" seems to require a higher small-block read/write speed than most cards have. Two things seem to affect it: 1) brand (sandisk is currently the only way to go), and 2)it seems that higher classed cards sacrifice the small block performance a bit. This makes sense to me, since the classification related to large block sequential read/writes (iirc), so some trade-iffs are always expected.
See this thread for useful things.
And I think most people are buying the smaller card mostly because of price, and partly due to a herd mentality on threads like the above.
Sandisk 16gb is just fine for running the Rom off the sd card; that is my current setup.

I was referring to the specific instance of using transcend for running cm7 for example. I understand transcend and patriot are decent when used for data, and I have PNY cards in our cameras, so they seem to work fine for data.
I have a wintec SDCH 16g class 4 and it works fine, but I only use it for data.
I've been looking into this, and here's what it boils down to:
Most MicroSD cards are set up for data transfer aimed at large files, such as video or high resolution pictures. The majority of the market these cards are manufactured for are digital camcorders, cameras, and smart phones with cameras.
They've gotten great at streaming media to and from the cards, and using them as storage mediums.
Running an operating system from the card requires a whole lot of small data transfers, which is not a specification that manufacterers pay much attention to. Most people would never notice improvement in this area of the manufacturing process, so the companies don't waste money on it.
Different manufacturers have different ideas of what their product should be capable of.
SanDisk is the brand that has consistently tested better for small data transfer then other card makers.
Running programs/operating systems from a MicroSD card is a new animal, something that hasn't really been done before now, and the tablet market is still in it's infancy.
I'm sure this issue will be addressed by the hardware makers of memory cards over the next year or so, but for now we are stuck with the task of trying to figure out what works for our purpose given what's available on the market right now.
All this being said, out of a handful of cards I own, my 16 gig SanDisk class 2 MicroSD card is my highest performing card - more then twice as fast as even 4 out of 5 of the 8 gig SanDisk cards I have.
Here is the link to the software we are using to test the cards: Crystal Disk Mark
Post 5 in this thread has a link that takes you to the one that has become our communal benchmark thread, and has a lot of info on this topic.
I would surmise that a 32 gig SanDisk brand card would probably be pretty good given that:
-Sandisk 8 gig cards (in class 2 and 4) are the general recommendation
-SanDisk 16 gig cards consistently test to a higher performance level then the 8 gig cards.
If this is the beginning of a pattern, and the larger capacity SanDisk cards are inherently manufactered to a higher small data standard, then theoretically the 32 gig card would be better.
But, this is only a theory. A 32 gig card is more then just a couple of bucks, and I don't think we have enough benchmarks on them yet to say one way or another.
Even with the SanDisk 8 gig cards, there is a wide range of what you could end up with on small data transfer speed. It's kind of pot luck. Even the slowest ones are many orders of magnitude faster then most other manufacturers, though.
This would be a good thread for people who do have 32 gig cards of any brand to chime in on, so we could keep the discussion about the largest supported capacity card on the Nook seperate from the other threads on this topic.
I saw a thread a week or so ago regarding testing class 4 cards and which were better. I just ordered a NC the other day. Anyone know the thread?

You might mean my thread on comparing speed results between different readers using the benchmark software.
It's more a look at the testing software and methods of doing so then the actual cards themselves.
The more people who post benchmark results in the thread skwalas linked to back in post 5, the better of an idea we'll have of what works for us.
The amount of information we've collected so far in such a short time is astonishing - this is a great community.

Sandisk 16gb, Class 4; Got it from Radio Shack a month or so ago on sale for like $25.
32 Gig

Bought this one about a month ago. Transferred my 16G class 2 from Radio Shack to the 32G then expanded the partition. I run CM7 off the SD. Works GREAT!. I run movies, apps from the card with tons of room.
Thanks for all the replies! They been very helpful!

IIRC, Lexar splits their Class X cards into two more classifications, a regular and an Ultra class. Which one was yours?
Also, Radio Shack currently has 8gb Sandisk C4 cards for sale at 14.99. Perfect for playing with an SD install. With Crystal mark and a cheapie USB reader I got 2.5mb/s read, 1.5 mb/s write (both of the small block ones). I believe these are the important ones for an SD card based ROM?
I suspect the main reason there's not much info out there on 32GB cards is that people are less willing to drop $50-80 on something that may not work (IF they're trying to run a custom ROM from the card). If you're not trying to set up a custom ROM install on the SD, get any card you want--you may appreciate that higher sequential read/write in the higher class cards when you're moving multiple GB of movies or music to and from the card.
From everything I've read, the size of the card makes no difference whatsoever. The only reason people harp on the 8GB and 16GB Sandisk cards is because those specific models (both class 2 and 4 in those sizes) have been tested many times and return both reliably high small-block random writes and positive anecdotal reports for running ROMs. The size, manufacturer and class are irrelevant in and of themselves: they just let us identify specific models identified as most consistently working well.
Also, CrystalDiskMark is not malware: just do a custom install and choose not to install whatever is bundled with it (do this always for all software, I'd say). It's whatever program they use to suggest other software that triggers the false positives in security programs.

What 64GB card are you using?

What make and model 64GB card are you using?
I just bought a 64GB SanDisk Class 10 that comes formatted exFAT (curse Microsoft with their damned proprietary filesystem and convincing gullible vendors to license it. I'm looking at you Sharp). I stuck it in the Atrix HD and formatted it when prompted at first boot with it in. It was mounted for a bit, but I couldn't write to it and whenever I launched Settings and selected Storage Settings would crash. I just re-partitioned and reformatted it FAT32 in my laptop using a combination of diskpart and Acronis DiskDirector 11 Home. At the moment I am waiting for my files from my old Lexar to be copied to it before I stick it in the Atrix HD again. Will suck if the HD has problems with this card. Can't complain about the brand as SanDisk is one of the inventors of SD cards, including MicroSD.
I'll report back what my experience is.
I thought the Atrix HD was only compatible with SDHC cards (thus 32 GB maximum capacity).
The cards that are 64 GB (and higher) are SDXC, and not compatible.
I got this one when it was on sell a week ago for $43.50 shipped.

Yeah, it isn't just the reviews; Motorola's specs state "Up to 32 GB microSD," but as was pointed out before what they really mean is MicroSDHC cards. However, as these are all extensions of the SD format one would hope that SDXC cards would work. I've seen a few other reports of people using 64GB cards with the HD w/o problems. I'm just curious as to what has been the experience of the people here as they are generally a good deal more tech savvy than on the other forums.
So far the only hiccup I've had is that it wouldn't format the card. Also twice I've tried to unmount and then remount the card, after which the phone thought the card had mounted, but it wouldn't use it. A reboot fixed this each time.

I formatted my card in my phone, put it in my pc and copied 33GB of mp3s, then copied the stuff from off of my old card 23GB, then some tv shows. I watched the tv shows from my phone, deleted mp3s and recorded a movie. I have yet to unmount and remount.
have you tried searching for this? I remember there being a topic about people using 64GB SD cards already in this forum
