2 days ago the SD card, that came with my Desire died. It was a 4 GB Class 2 Sandisk, so it wasn't really the best of the best, but it never really felt sluggish, or anything. It had a 512 mb ext 4 partition, and I used it with MIUI XJ X-Part ROMs. It was quite fast, so there was really nothing to complain about. But it died horribly. Couldn't reformat, it looked like it only has 30 mb space, tried just about every solution google and xda had to offer, nothing helped.
So, I decided to buy a bit bigger, better one. Yesterday I bought an 8 GB Kingston, class 4. I figured, that it would be slightly better, since it supposed to be faster. I created a 1024 mb ext 4, rest is fat32, so I'd have plenty of space to app2sd+. I made some test with an app named SD Tools, and it says it in fact is a bit faster.
But here's the kicker. The phone is much-much-much slower, in every aspect: the boot takes 3-4 times longer, some of the apps are sluggish and take more time to load than usual, Titanium Backup takes forever to restore the apps, and even it performs the backup (and the restore) in _recovery_ significantly slower. If I delete the ext partition, and format the whole thing to fat, the boot takes the usual time, and as far as I can tell, everything is back to normal.
What could be the problem? Could it be, that I ****ed up something at the partitioning? Maybe the ext partition is too big? I tried modifying the read_ahead settings too, but it didn't really help. I use the newest MIUI XJ XPart (1.4.8). Thanks in advance.
I know it doesn't help much, but i bought a 16gb class4 kingston msd card to replace the card that was included with my desire and it seems to also under-perform as you mention.
Subsequently, i have picked up a samsung 8gb class 6 from Play.com for only £12.99 and the performance is awesome. I would highly recommend it for the desire!

ah, man just bought one of these myself and I'm waiting for it to arrive. Reckon it's worth giving it a shot in my phone, seeing if it's actually good enough, or should I send it straight back? What ROM were you using?
My boot time got better after a while. I tried every possible combination of a second partition: 512 mb, 1024 mb, ext3, ext4, with or without linux swap. Nothing really helped. Finally I decided to go with 512 mb ext4, a 32 mb linux swap. The first boot was like 10 minutes, but from what I understand, that's to be expected with this kind of ROMs. But even after that it wasn't booting that fast: 2-3 minutes on the HTC splash screen, and then and other 3-4-5 on the ROM's boot animation. (I was actually timing them while watching TV).
But I finally decided to let it go, I accepted that nothing I do can change this, so I started to setup the apps & stuff, and I tought if it's still really slow, then maybe next week I can buy another (different brand, maybe Maxwell) SD.
But. The bastard started to get faster. I noticed that the boot after changing the theme with MIUI theme manager was way to quick. Decided to time it again. It was 4 minutes. That's considered FAST seeing the prev. boot times. I restarted twice, with the same result: 3-4 minutes. I didn't really know what to think. I went out shopping some food, talked with my girlfriend, watched an episode of Bones, etc. Just out of curiosity, couple of hours later I decided to do another boot test. It was just under 2 minutes. What. The. Hell.
Fired up the previously used SD Tools, did 4 tests, just to exclude any "false positive". The reading speed didn't really change, but the writing got faster. Like 2,5-3 times FASTER. Some of the apps still seem to be starting slowly (yes Tweetdeck, I'm talking about you), but it's a LOT better, than it was right after the install. Weird. I know that with A2SD+ ROMS android is copying some stuff to your SD on the first boot and stuff, but it's been like 10 hours since that install... I don't really know what to think.

Hi all,
Recently, i have changed to Sandisk Mobile Ultra 16gb Class 4. Did a speed test on it with atto benchmark and it is able to read/write with an maximum of 19mb/14mb per second.
However, when app2sd+ is applied, I found that in certain apps or games, there is still an lag with the applications. (This is most obvious in games). If app2sd+ was not apply, such lags are seldom seen.
Thus, I feel that having app2sd+ is a great incentive for large storage but at the price of speed.
Are there any available tweaks out there that is able to improve the speed of app2sd+?
Pardon my poor english.
Thanks.
BR,
Ruffie
Yes, I suppose. I use a Kingston Class 10 microSDHC and I've never had such problems. I can move whatever I want to that card and cannot find any difference. Also, navigating across 300 images is very smooth.
But sadly, Class 10 cards are still very expensive, especially if you want 32 GB.
Would a Class 6 be good enough you think?
There must be something wrong somewhere.
I've had a Class 2 16gb Sandisk card since back when I had a G1.
I've used APPS2SD+ all the time on the G1 and used it for a while on the Desire until I moved on to Cyanogenmod.
All my apps run as tho they were installed on the phone, regardless of what people used to say about different classes.
I have some big games installed like Fifa 10 and Zenonia and get no lag at all.

i played caligo chaser on my desire.
this game has some obvious lag when i am using app2sd+. but show no lag when i install them on phone.
not sure is it because, it is writing to both fat32 partition of the SD card and ext 3 partition on the same SD card at the same time when it is running thus causing the lag.
Does anyone know at what speed is the phone capable of read/write to the SD card?

Hi chaps
Purchased a Kingston Class 4 32GB MicroSD today
However, since inserting this card to my phone it has become unrealistically slow. Lagging all over, force closing to no end & just extremely sluggish & unresponsive on many tasks. Forget browsing the music/picture library, it just shows the 'loading' icon etc. Everything related to the SD takes ages to load or cache.
I've tried formatting, rebooting etc & this persists. I can't for the life of me understand this. As you can imagine this is extremely frustrating coming from a stock Class 2 SD 8GB Card. Is there a particular procedure in which to format the card or something else?
Looking like a right waste of money thus far 'sigh'
Cheers
Looks like I jumped the gun, seems like the phone was just sorting itself out but all is in order. If a mod passes eyes on this thread, please close.
Hi Guys,
I am having a problem loading some of the new 3.0 roms that are out now...and I was wondering if this might be the issue.
I have the stock SDCARD that came with my evo4g (8gb)...but when I insert it into a card holder in my PC, it only comes up as 5.67gb total. Even when I try to format it...it only says 5.67gb.
Is that normal?
Thanks!
The biggest problem with our SD cards is the type of card it is. our "class" is really low. they SHOULD have put real cards in our phones like class 10. I personally did test both on read and write speeds while in the phone and the class 10 was MUCH faster than the stock. get a 16GB.. btw, it'll never reach 8gb, or 16gb. it'll always be less.

Yes, I understand all that...class, etc...and I know that after formatting it will not be 8gb due to 1024 equals 1gb...but 8gb down to 5.67gb? That seems a little low right?
no. because as soon as you format it and put it back onto the evo... it re-adds its stuff to the sdcard. and also.... the math isn't right. you forgot about the partition table which takes even more away. Depending on how you format it if it is fat32, NTFS, WinFS*I REALLY WISH MICROSOFT WOULD DO THIS! LOL* well, the size of the disk will change. well, I mean the amount you can use. oh and also the unit size can change it.
Do you have an ext partition on the card (for apps2sd)? That's the most likely place the extra space would go. The space you're seeing reported in Windows is the FAT32 partition.
If you don't think you have one, have you ever had one? If you thought you had gotten rid of it, it's also possible you didn't really get rid of it, depending on what you did. Just reformatting it in Windows won't get rid of it.
An 8GB (marketing) card will normally have about 7.45 GB of actual space. So you're missing roughly 1.75 GB.
I brought one, formatted it to fat32 and created a partition of 2gb also fat32 using minitool partition so I can use link2sd, but my phone keeps randomly rebooting and apps are force closing, not all the time, but alot of the time, i never had the problem yesterday while using the 32gb sd.
Not sure if i can solve this and is this usual for the 64gb
my phone still keeps rebooting after testing for a few days, at first it's fine but as i gradually try and fill it up to about 21GB now the phone just constantly reboots with force closes and widgets not loading so im assuming 64gb isnt really that compatable, might be worth going back to the 32GB? sd
I have 64gb and have had it for months formatted it to fat 32 via windows I haven't made a second partition though aparantly 1gb is supposed to br max? And are you sure its a real when ever I buy asdcard I always use a program that tests it capacity

Thanks for you're reply, I brought it from amazon directly not a third party, i doubt they would rip me off, i have formatted through the computer and phone using fat32, but i haven't tried it without partitioning it, maybe that could be the problem?
I was able to partition the 32GB to 2GB without any problems but as it's a bigger card it could cause problems, will test it out
How would i test to see if it's real and what would the results show?
I bought mine from amazon also and I used a programe on my computer that i downloaded can't remember what is called but I remember there being a few it took like a hour to test though but I honestl don't know what's up with it you could try not partitioning it for awhile :/ but I have nearly used all the space on my card and experience no problems got about 5 gig left there's also sd tools on the play store or you could try wiping the card completely and starting from scratch :/

I have wiped it and starting from scratch using a 961mb partition just under 1GB as i read it can cause problems hopefully that will sort it if not i will try last resort with no partition, do you have the problem with low internal memory with not having a partition, that's only reason why i chose to do this on my 32GB as i had about 8GB left but i wasnt able to use it.
Nah I don't realy need it I havr 110 mb free and that's with wildblood 52 mb orderandchaos 23mb gangter rio 14mb dolphin browser 14mb and that's the big ones I have loads of games 68 on my play and 200 apps alltogether I do want a second partition but don't have a computer atm does using the second partion makes games run slower and can you move the data aswell as app? And can you movedalvik to sexond partition?
Sent from my R800i using xda app-developers app
I dont notice any difference in games slowing down just the same, it doesn't move all data it just uses the app but where as usually you have the app installed on your internal and the data of the game goes to you're sd, you can have both on your sd, keeps all your space, well thats how it worked on my 32GB with 2GB partition but maybe the 64GB causes problems with bigger partition doing that, i'm not sure about the dalvik catche.
No luck, woke up this morning picked up my phone and bang froze, twice rebooted and force close apps everywhere with my home screen widgets not loading, trying now without partition, last resort, otherwise im back to 32GB
after my conclusion i am still having reboots, trying back the 32gb if it still occurs then it's more serious then i thought.
i have also flashed stock firmwire just to see if that was causing it

Weird. I really don't think I've heard of one of these SD cards acting like that for the Play. SanDisk is normally pretty reliable in general, too.
If interested, I'd trade you a Samsung Class 10 that works great in my Play and has pretty good random read/write speeds as well. Although you'd be better off returning yours for the cash.

I will keep it and use it in something else, if it's not faulty, I don't understand it either I did research and seems to work with everyone else.
I don't mean to be rude or ignarant but how do you use app2sd as i am having no lucky with link2sdor any other low internal storage, i keep wanting to go to my 64gb as 32 wouldnt be enough, i love my games and want a phone full
thank you for your feedbacks.
at the moment it seems the problem is while charging overnight
I have a Sandisk 64Gb MicroSDHC card. I've been using it for sometime on Android and. I've used Android to format it but never to partition it. I've also used Android to wipe data on the card. I've formatted it varous times again on Ubuntu.
The card was working fine but today, I decided to format and clear all the data on it. Much to my dismay, after when plugging in the card and formatting it, Windows read it to have only 27.8 GB space even though it was empty. Ubuntu also showed 27.48 GB only.
I've not much problems with the card on Android and Ubuntu but today, this serious problem occured. Just how does a 64GB card reduce to 27.48GB? I've formatted the card to FAT32 and EXT4 multiple times to no avail with GParted.
Previously, some time ago, I've formatted the card to FAT32 and because the computer, I forgot if it was Windows or Ubuntu and because the computer read it as having 30GB space, named the card 32GB Volume or something like that (The name has long since changed to one of my choosing). However, Ubuntu still read the card as having 64GB of space and filling it up with more than 30GB worked just fine.
What happened? How do I resolve this? I need the card to work on both Ubuntu and Android.
This is my card. http://www.amazon.com/dp/B005V7WIA2 Based on reviews alone, it seems to be very good quality. I've used the card on Ubuntu, and Motorola Defy (Android), and the Motorola Xoom (Also Android). Both Android and Ubuntu have worked with the card just fine except for one thing Occasionally, when copying files to or from the card, I get an error message. Sorry but I don't recall what the message said.
Also, sorry for this mess of a post. I'll try to reword it once I have the time or overcome my exaggerated grief for this unexpected tragedy.

Use h2testw and check if it might be fake (i.e. actually 32 GB, but re-programmed and re-labeled to say 64 GB).
I got delivery of a new 32 GB thumb drive an hour back and am running the test as I type this. Makes sense to test out all new flash memory purchases as soon as you get them. Lots of fakes going around.
If at all yours turns out to be fake, then you're lucky you got a 32 GB, and not a 2 GB! Hope yours is not such a case!

I bought it from Amazon not Amazon Used or Amazon Marketplace. Oh well, I'll still check it out with that program you suggested.
uhm.. interesting... now i understand...
