microSD 32Gb class 6 and Galaxy S

I am thinking about purchasing a 32Gb microSD for use with my galaxy S.
My concern is that, is this too large? Are there any bad side effect like it being too slow to display picture/start up scann/run applications?

Which brand? That's probably more important for the speed than class (a class 2 Sandisk is often as fast or faster than a class 6 from a lesser brand).
The capacity of the card shouldn't affect the speed during most situations. However the phone does scan for media each time it is turned on or after disconnecting from USB connection (Kies or mass storage), the amount of time this takes depends on:
-the amount of media stored on the card and
-(probably) the read speed of the card.
Note that class rating is minimum write speed - so it's not a great indicator of real-life performance.
Also note that some too-cheap-to-be-true cards are actually smaller capacity cards that report larger capacities to fool the customer.
BTW where are you getting the card from (I want one as well ).

Hi flamingpitofhell,
I am looking at Sandisk as well and most likely get it from their online store. I am trying to find more information whether it is worth the trouble.

I don't think Sandisk sell class 6 cards (yet). Buying from their online store's also more expensive than online retailers (I can get one in Australia for AUD155, which is ~USD137, cf their RRP of USD200).

thanks for the pointer. will look around for local stores here in Thailand.
Which city in Australia are you in? I studied in Perth more than a decaded back.

I'm in glorious Melbourne mate, haven't been to Perth yet

the only LEGIT 32GB Sandisk available right now in the market is only Class 2
if you read anything else, it is FAKE, specially from eBay
wait until the other microSD manufactures start pushing out 32GB on class 4 or class 6 before buying.
i'm using 2x 16GB Class 6 until the 32GB class 6 becomes available.

I'm using Class 2 32GB card in mine, its fine.
Its slower when you're transferring to the card from your PC, but for most people thats only particularly problematic the first time (loading music collection), after that you'll not really notice a difference in the phone (the read speeds are basically the same, and the phone can neither read nor write to the card faster than a Class 2 card can cope with). You can see it in the benchmarks taken post-mimocans fix - Class 2 cards are no slower than any other Class within the phone.
Grab one now and be happy.

Where did you get yours from and how much for. I`m interested in getting one myself.
Thanks

my local stores already carry the real Sandisk 32GB class 2
too slow for my taste, i like to run Apps from the SD card, also use it as a SWAP partidion to prevent the LAG problem people complains about, it's a very easy fix
http://forum.xda-developers.com/showthread.php?t=724251

i wonder what would be better a 16gb class 6 or 32gb class 2...
is it worth sacrifising double of the memory for the speed?

it depends what you are trying to do
if it's just to listen to mp3, then Class 2 is fine
if you want to run games, software, watch movies, use it for SWAP drive to have no lag, then minimum a Class 6

Class ratings don't really seem to have too much of an effect on real world performance: http://forums.whirlpool.net.au/forum-replies.cfm?t=1468705. Just discount the last result from the SGS (it's most likely mistaken for the internal SD).

i rather trust my experience coming from PalmOS + WinMb where real life situations using a class 4 or slower cards, made a huge word of difference when launching applications from SD and watching movies from SD
funny enough the numbers reported on that topic shows SGS i9000 to have the fastest speed even using the same card that got lower speed on the other phones.
which seems to point out it's directly proportional to the CPU speed, and the multitasking software running in the back end.
however as you see on those test itself, there are speed differences between class 2, class 4 and class 6
the same class # can not be compared to another class # of a different size,
if you imagine a hard drive, the bigger the hard drive the more layers/disk area it has to read, the same is true even for static SD cards.
however as pointed on those test Transcend usually has the fastest SD cards in the market, that's why i always buy that brand for performance, using a 16GB Transcend myself, waiting for the 32 GB class 6+ to come out
Adata has 2 lines, the performance line, and the standard line
if you want speed get the performance SD cards
Kingston and Sandisk are mostly standard speed, they don't release much performance level SD cards anymore, but they do have lots of those on USB sticks.

I tried my Brothers Sandisk Class 2 32GB and it worked perfectly.
Granted it's not as fast as my Sandisk Mobile Ultra Class 4 but that card flies anyway.
Certainly for recording your large movie files taken with the camera it's no different in speed than using the built in SDCard on the phone.

I have no problems watching 720P video on my phone. I have no problems launching applications either.
So much misinformation...

of course there is no problem, the issue here is getting the top performance, any SD card will work just fine.
it's just a matter of how fast/slow are you able to torelate

The only time you will notice any difference in speed is when transferring data to and from the card.
However, when you have double the space of other cards to consider speed should not be a deciding factor.
I'm already looking to get the Sandisk Class 2 32GB card. It will store all of my work files normally kept on my Laptop.
My Sandisk Class 4 Mobile Ultra 16GB will be my spare ~ should the larger card fail...

Thanks for the information s everyone.

I have the 32GB sandisk card and works perfect. I have a 720p mkv file and my music on there. Playback was superb for the video with no noticeable lag. Mind you the card isn't anywhere near full yet. From my limited knowledge of sd cards, they put data on the fastest part first so the fuller it gets the slower the card is likely to get..
My plan is to put movies and songs on the 32GB file and reserve the internal 13GB for capturing video and taking pictures on the phone.

SD read/write speed causing lag on my HD2 but...

So I downloaded this app call H2testw.exe to test for legit sdcards but it also tells the read/write speed as well. I am testing my 8gb and 1gb cards. I set it to write a 300 mb files to the card and verify it.
Info about Android running on the two cards:
8gb = lags coming out of sleep, touch screen freezes, write~7.5 mb/s, read~12mb/s
1gb = no lags, no touch screen, write~4.3mb, read~13mb/s
I'm confused. The read speed is almost the same yet the 1gb microsd is more responsive running MDJ android compared to the 8gb microsd. Any thought?
UPDATE: Maybe this is what's causing the problem. Stolen from Engadget.
What we've learned from our tipsters and from documents culled from Microsoft, Samsung, and others is that the big issue is random access performance -- a figure that isn't taken into account in a card's class rating. Ironically, Microsoft discovered in its testing that cards with higher class ratings actually performed worse on Windows Phone 7 because the tweaks card manufacturers make to achieve high sequential throughput can actually hurt random access times. There's some rocket science involved here, but basically, it's a tradeoff and a bit of a gamble -- if a manufacturer tunes a card for a high class rating, it takes more time to access the first byte at a new location on the card because it's optimizing access for that area of memory, but once it does that, it can blast sequential bytes at very high speed. If you've got a lot of small reads or writes you need to make to different files at different locations in the card's memory, though, you really start to suffer. Cards with lower class ratings tend to spend less time optimizing sequential access prior to the first read / write operation, so it can move around the card (that is, access it randomly) much faster.

They are probably different classes, plus it naturally takes longer with a bigger card because there's more files and more space to read and write

I get screen freezes with 8gb and up but rarely with new builds, haven't tried a card higher than class 6
Also I'm on radio 2.15

Oddly enough, I have two 8gb cards, one class 4 the other class 6, and they hiccup more than my 16gb class 2.
Now that is weird.

I'm lost myself...I'm thinking off just getting me a 4gb card and hope for the best...

I heard the 16gb class 10 is perfect but it still cost to much for nand to be around the corner

Cheapest 16GB - lags from time to time :/
Maybe defragmentation may help?

Defrag wont help...scan for errors...try to have only the android folder and see if it makes a different ..

Btw, guys...
all sd cards are not created equal. all sd cards of the same CLASS are not created equal.
Check out the ongoing drama with win7 phones with SD slots....
class measures throughput, what affects the SOD and related issues is random access speed, not throughput so much.

It's just my 2 cents, but I've tested Class 2, 4, and 6 MicroSDHC cards and found very little noticeable difference once Android is fully booted up and running on the HD2. Moreover, none of the cards create screen freezes or SOD issues or high battery drain problems here. That said, I have noticed that the actual boot time and file transfer speed (from the PC to the card) can be faster on average with quality higher class rated cards of the same size. Also, I've found that the larger the card size, the longer the android boot time, no matter the class. Guess that makes sense, as the system need to read more sectors with larger size cards. Please note that I've only tested Sandisk, Toshiba, TopRam and Samsung cards to date. What's kind of strange is that the Class 2 16 & 32GB Sandisk cards run just as well or slightly better for some reason than some of my higher class rated cards. Go figure...
As far as issues go, I recommend only using quality brand name cards, no ebay fakes or cheap no name brands. Also, I've had great luck formatting all my cards with SD Formatter v2.0 and v3.0, using the quick format mode with the standard 32kb cluster size.

Great info here. I think I will just order me a new card from a reputable brand. Maybe my card is just getting old. Maybe a 16gb from Amazon will do. They aren't too expensive nowaday. ~$26.

Does the Radio version effects the lag of the sd card? Or the kernel?

No, not on the sd but radio does effect how the build will run, your phone calls, your battery.

Could this be the reason why class don't matter on hd2 android? I mean even some class 4 & 6 have lag and sod problem. I pulled this bit from engadget. It's an article on wp7 and memory card issues.

Obviously.
Been saying this for a while, myself - I have experimented, and I get SOD every time with my 16gb class 6 card, but rarely with my class 2 8gb, and never ever (and, tbh, better responsiveness overall) with my 2gb NON-HC card

I hope so...my class 2 16gb will be here in a couple of days...i hope it's faster than my current 8gb class 4....
Update: my 16gb class 2 sandisk is here. Things have improved alot. Wake up is faster now with less lag, market download speed is faster now (10kb vs 100kb). Hopefully system performance will be better...

[Q] SD Card Worth It?

I am going to pick one of these up, but before I did, had a quick question (anyone with a WP7 can answer)
Do you feel that 8gb is enough space? Or do you wish you had more? Should I get an SD Card?

Most definitely. I have loaded most of my music and a few videos and I already used over 6GB. That's pretty much all the stock phone has. Now, I have over 14GB still left. Might put some movies on it.

My only disappointment in the focus is the 8GB stock NAND. For a $199 on contract device, 16GB really should be the minimum, especially considering a few other WP7 phones, to say nothing of Android phones and the iPhone, all start at $199 with 16GB.
That said, adding the SD card isn't that big a deal as long as you do it before you've filled the device up. For some reason there seems to be no ability to do a full backup of the phone by any means I've been able to find.

The problem with the SD Cards is that there's intense confusion/miscommunication about which cards work well. Just because it works with 6GB doesn't mean anything. What seems to happen is once you get to 8GB filled, the phone's performance takes a nose-dive, sometimes leading to losing all data.

"Enough space" depends on you, not us. I have an iPhone, iPad and iPod, all 16GB units, each with some 14GB or so of music & apps on them so it the first thing I did when I brought the Focus home was slap an 8GB card in there, format it and load it up. I have maybe 2GB free and it's worked without a single glitch for the past two weeks. For reference, mine is a Sandisk class 2. People seem to have problems with cards other than Sandisk and other than class 2 and I noticed absolutely no performance problems so if you're going to try it, try that and keep the receipt in case you need to return or swap it should something go sour.

Enough Space?
I agree with Mark, whether there is enough space or not really depends on what your usage requirements are.
I had a 32GB Zune and when I bought my Samsung Focus the Zune had over 20GB of data on it. So for me adding and 32GB SD card to the Focus was not only a desire but a very strong selling point for the Phone.
And yes, I am seeing a few issues with the Sandisk Card that is in it. Currently they are not enough to make me yank the Card because I (again) bought the device to specifically be a convergence device for myself and I am at heart a tester and tinkerer so figuring how exactly how WP7 works.doesn't work with an SD Card and the statement that MS and Samsung are working on a fix is enough for me right now.
Smaller Sized Cards seem to be more reliable than larger cards (not to mention less expensive) but that appears to anecdotal evidence as well. My 32GB Sandisk only causes freezes and resets when on Battery for example and I've not had anyone else confirm if they are seeing the same.
Not great answers but, hey, this is the fun of learning as we go along...

I have more than 11GB on my Focus with no issues at all. No slow-downs, no hiccups, no data loss period. I am currently using a PNY 16GB Class 2 card. I previously had a Centon 8GB Class 6 card with the same results.
If you read the thread on MicroSD cards, it seems there are some cards that have been working pretty much flawlessly. Both of the cards I mentioned have worked perfectly for me. I gave the 8GB to a friend and he is using it in his Focus as well.

For me, to really make a portable phone/audio/video device be best for me it would need at least 150GB of storage... and a few TB if i wanted to listen to music lossless and a few movies.

You know, I was thinking about this the other day...the phone has 8GB of internal memory and if you put in an SD card it stripes data across it and the internal memory. If the card is 8GB or smaller that's fine but what happens if the SD card is larger than internal memory? It doesn't stripe the first 8GB and set the rest up as another partition and it does appear to use but it can't be striped. Now you've mentioned that smaller sized cards work better and my 8GB card works perfectly. I wonder if the file system's attempt to work with a larger card is inherently unstable? I know that if you put two different sized drives in a Windows box and stripe across them you will only end up with double the size of the smallest drive, not the actual sum of the two. Might be an interesting poll...indicate the size of your SD card and if the phone has been 100% stable since inserting it.

I'm not totally convinced based on comments in blogs that the disks are "striped". I think a lot of people are saying this and maybe using the term out of context and everyone just keeps using it. Has Microsoft actually come out to say "WP7 performs RAID 0 configuration"? For a phone OS which was never intended to see anything other than a single drive, don't you think throwing a RAID controller in there just for kicks is a little absurd?
The other term is "span" and if I had money, I'd bet that the two disks were spanned as a single partition, as opposed to striping like RAID 0 does.
Despite all of that, I have tried a 16gb class 4 with more issues than I cared for and currently have an 8gb class 4 with negligible issues. Any card you get, I'd run on Vista/Windows 7 and test for ReadyBoost. That at least tests the card for random access speed, which is important. My 16gb failed readyboost and had lots of issues in my Focus, whereas the 8gb passed and the only issues I've seen with that one are issues that other people might have experienced on their own phones sans sd card.

I've read both, striped and spanned...who knows. Considering how slow SD memory always was in old WinMo devices, I didn't think it absurd to stripe data to provide the same kind of speed boost you get when striping hard drives. Hard as it might be to believe, it may have just been that WinMo was slow. I hadn't thought of the readyboost test, that's a good idea. Readyboost is pretty picky.

[Q] does a class 10 micro sd card benefit in the A500?

Sorry if this was already asked but I tried searching. What type of class micro sd card will I actually benefit from? A samsung class 4 32gb is out there for a good price but if the tablet will actually take advantage of a class 10 I would get one of those.

for the most part it will not. Except in moving large files to and from the card.maybe playing movies from the card.but even movies are OK on 4.6 class cards..if you could run apps or have there data from SD card then it would be a big improvement. I have used a 8 gig class 4 and now have a 32gig class 10.can't tell much difference other then when pushing roms and other large files to my tablet over USB.
I would say get 6 minimum but if you have the cash faster is always better. Just don't go out and spend the money if you have a class 4card.
Im sure you will hear diffeent from others.

Not really. I have 5 sd's, and no difference between class4 and class 10.
Up to a certain size that is. Anything more than 16gb, and I would move to a class 10.
Rumor has it, that you can run a 64gb. If you partition it with Partition Magic.

I think it depends on what you are using the card for. I don't think it is the tablet that would take advantage as much as a particular app that would. If you were using apps that required fast read/write access to the card (and you were actually using the card as opposed to the internal memory) then the faster card would be best. Keep in mind that not all class 10s are the same so also make sure to look at some of the benchmarks for the different cards. I know in terms of photography and hd video captures that a higher class card really does make a difference...but that is just an example of a real use application.
Hope that made sense.

MicroSD Card - Which?

Hello,
It seems NST can be fussy with MicroSD cards so a thread to determine requirements would be fantastic:
1) MicroSD, MicroSDHC and MicroSDXC - Which are supported? Which are recommended?
2) Capacity - After rooting what reasonable size card is required (basic app installation and an 'average' library)?
3) Class rating. You might think bigger is better but I've read reports that class 10 are no good. Similarly, below what class rating is the performance impaired?
For my own part, I am interested so that I either use a card I have or buy one as necessary. I have a plain old 2GB MicroSD (not HC or XC, and therefore without class rating). I'd like to use this to save a bit of cash (and because I've got it here ready and waiting, otherwise unused) however I'd like to be sure that it will operate acceptably both in terms of capacity and performance.
Thank you!

I used my NST for a short while with an old 2GB card, and it worked. I upgraded to a 32GB SanDisk Ultra Class 10/UHS-I SDHC, because I use Aardict with offline copies of Wikipedia etc. (~16GB or so) and it wasn't really economic to buy anything smaller or slower new. However, I've run into problems with the SD card disappearing until after a reboot (even with latuk's kernel with the Class 10 timeout patch that I pointed out to him), and when it comes back, it sometimes comes back with a corrupt filesystem (presumably as a result of the unexpected logical disconnection). I'm putting this down to the Class 10 speed of the card, and I've ordered a replacement Samsung 32GB Class 6 SDHC which I expect to be able to test soon.

Thank you for the reply.
So;
1) Is 2GB enough for 'normal' usage - Stock apart from i) rooting, ii) Kindle App (and dictionary), iii) Launcher 8, iv) small collection of Kindle books (for future proof, let's say <100) and v) misc small apps (e.g., BBC News, BBC Weather)?
2) If Class 10 is to be avoided - Will there be any 'real life' speed difference between a SD and a Class 6 SDHC?
Thanks again!

Apps live in /data which is ~800MB of the Nook's built-in memory. Android 2.1 has no 'move to SD' option, so apps will only use the SD card for caches and offline data (e.g. like Aardict). epubs are usually a few hundred KB, so even if you only have 1GB free, that's still ~3500.
I don't think IO speeds are much of a factor when reading books on a Nook; the CPU and eInk display are probably far more relevant.

SD Card for me like most holds books which are tiny. I do use it to store titanium backup path. I have a few BnW Mangas on there. 2GB should be more than fine. If your buying a card then get a 8GB / 16GB / 32GB class 6 whatever is cheapest GB per £ or $
Class speeds have greatest affect on the write speed of the card. For my other less fussy devices I tend to use samsung class 10 32GB cards which are quite cheap at around £20. They seem just as reliable (or I should say as unreliable) as more expensive ones which have died on me.
I wish I had a cache of little crappy sdcards as I constant have to put disk images on them to flash an android device and it usually involved me backing up one of data sdcards and retask it.

Thanks for the help - I think I'll give the 2GB a try. I can always replace it if it is not up to task and it is not doing anything else, so...
For books (only use I'll have for it) it would seem capacity is a non-issue. As for speed - Well, it's not going to be up to Class 6 standard but I have my doubts that I'd even be able to tell... Especially after a numerous reports that in certain cases (small files) some higher class cards are actually outperformed by lower class cards. And, hey, after getting the guy so cheap the idea of another £20 on an SD card is not ideal. I'll report back if I encounter any problems. Thanks again!

Write speed is not issue when using as how often do you write the books etc to sdcard. I only mention it for if your spending money.
Trouble I small or low speed sdcards are still usually around £5 min so its does not make financial sense to buy them. Also beware buying cards on ebay or similar sites alot of fakes. If there a few pound how cares but if your spending more.
Got an old phone in drawer? Might have a 1GB card in it etc.
