So I went ahead and bought the Microcenter Class 2 16GB MicroSDHC card, which is on the approved list, and aside from the irritating discovery that Zune doesn't actually backup the phone and let you restore it, all's working well.
But I think I'm perceiving something of a slowdown in the feel of the OS since installing the card. It's not massive, I can't measure it, but it just "feels" slower generally while navigating the OS, loading things, etc.
Anybody else notice this or am I high on crack? Oh, and just to be clear I'm using a brand new Samsung Focus.
The quality of the SD card make a massive difference. I first put in a 16gb no-name card into my Mozart, and I honestly thought I'd broken the phone in the teardown to get to the SD slot. The whole OS lagged and there were 5 second hangs on the frontend screen. Generally nasty.
I've since switched to a Sandisk Class 4 32gb and it's gone back to being completely fast and smooth.
From what I've heard, Class 2 might be a bit too slow for WP7.
OK, cool (well, not cool, but you know what I mean--at least I feel less like I'm hallucinating imaginary slowdowns! that's good to have confirmation. I'm gonna return this sucker and snag a sandisk class 4 then.
I also have a class 4 sandisk 32Gb in my WP7. I haven't experienced any slowdown. But then again I put it in right when the sales agent handed me the phone so I don't know if there was any difference.

In a few places my focus feels slightly slower with my sandisk 16GB microSDHC class 4.. but it's so minuscule that I could chalk it up to perceived slowness.

I've had zero problems with my class 2 and there absolutely was no slowdown whatsoever. Quality counts and it may be that size counts also. Mine is an 8GB Sandisk. I've been reading here and there that people who have had problems have cards larger than 8GB almost without exception. If you stripe two hard drives of different sizes you don't get the sum of the two, you get double the size of the smallest drive and the rest is ignored. You can make a partition out of it but that's immaterial. The phone is different in that you get the sum of internal and SD memory but I'd assume it's only going to stripe the first 8GB. If it hits that boundary in the middle of a memory operation does it suddenly have to switch how it reads that memory? If so, it is the source of some instability? I don't know but it is starting to kind of look that way.

Got a class 2 Sandisk 32GB card in my Mozart and there's actually no slowdown noticeable. Read somewhere that speed is not limited by the SD Class, but something like possible operations at the same time..

Really? I've read all over the place that it does, hence the need to reset the phone when removing or adding a card.
Got a new Sandisk 16GB class 4 last night, wiped the device and installed it--not only is it back up to its original speed, not only are there no waits for icons to refresh on the start page, but get this: I got an extra 2GB out of it. With the Microcenter card the system reported 20GB available fresh--with the Sandisk, it reports 22GB.
All in all, I'm going to agree with avoiding one of two things: either class 2 cards (which makes sense, even if the difference is really small), or Microcenter cards. I'm not clear which, butat least I can say conclusively that the sandisk card works well

Thats not why it has to be reset. Search works
Its cause of the way WP7 secures the card.

Have just acquired a Touch Pro 2 on eBay, and am now thinking about getting an SD card for it. I assume the TP2 supports SDHC...?
I can get a 16GB class 2 card for about £30, or a 16GB class 6 card for £50. Am I likely to notice much actual difference in speed between the two when used with a TP2?
Depends.
In day to day usage of the TP2, no I don't really think so. You're not going to be able to take pictures any faster (the camera isn't capable of fast shooting), movies will run fine from a slow card. Maybe searching through your email would be a bit faster, if you have a lot, but I can't imagine it will be significant.
Where you would see a difference is if you take your SDHC card out of the TP2 and put it into a PC for dumping lots of data on it at once - for example, copying over lots of MP3s or movies. If you're transferring multiple GBs at a time direct from a PC, you will notice a worthwile % increase with the faster cards.
So if you do that regularly it might be worth it. If you tend to change the data on the card only infrequently, then I doubt it is.
Personally I will be getting a slow card. I only have a fast card SD card for my Digital SLR camera, where the faster card enables more shots to be taken per second.
whatever you do do not get a Transcend class6 16Gb card. They are not compatible. I know there's a thread listing card compatibility in the rhodium forum, but I couldn't find it now.

Wow, thanks for the warning, that was exactly what I was thinking of getting.
firstly i beleive the class relates to write and not read speed.
second do not buy a card off ebay whatever you do.
i have come accross an a-data 16gb class 6 in my searches. in the end i got 8gb class 4 from play for a tenner delivered. may get a 16gb if i ever hit the limit. by then the price will have dropped to reasonable level.
i had a 2gb in my xperia and never filled it. i have a ipod touch for music and a netbook.

all the cards i have ever bought off ebay have been fakes.
some have worked but been slow. others have corrupt sectors. some have failed all together. thankfully last time pay pal refunded me.
look at www.sosfakeflash.wordpress.com/
buy the card if you want. that site has programs you can test it with to determine if its legit. i will never buy a memory card from ebay again.
Class only deals with write speeds, not read speeds BUT if the card has a higher write speed, it will normally have a higher read speed as well. (Though it's not a set rule).
Thx for the heads up. I think i'm going to risk it anyways. This seller has been on there since 2000 and has sold a ridiculous amount of flash memory ~20,000. I would hope the system would show some signs of fakery over that span of time.
I will try the tool you linked once it arrives tho.
Thx again
PS here is the ebay item # if you want to look: 380143609813
I decided I didn't really need 16GB of storage anyway, and ordered an 8GB class 6 card - a SanDisk Ultra. Got it from these guys on Amazon UK Marketplace.
They have a pretty high turn-over - nearly 30,000 ratings in the past year. I also used this tool to check whether the card was genuine or counterfeit. It passed with flying colours (no errors at all) so I think it's probably the real deal.
A quick, informal test (copying a 700MB file onto the card) suggested it was writing at about 12.5MB/s when the card was connected directly to the PC's USB port, and about 5.5 MB/s when accessed via the phone (in disk-drive mode). That suggests that the phone might get some benefit from a class 6 card, although it's hard to be sure. Certainly this a is a VERY fast card when removed from the phone and connected straight to the PC. (In fact the testing software rated it even higher - 14.9MB/s write, and 17.5MB/s read).
No reliability problems of the sort associated with the Trascend cards (although I'm not sure that affects 8GB cards anyway).
Trancend 16GB Class 6
I currently have a Trancend 16GB Class 6 and it works just fine.
I only buy cards from Sandisk and usually from amazon. EBay has a lot of fakes on it! I have a 16GB Class 2 from amazon that I picked up for $40. Speed test while in Disk Drive mode through the phone show a Write speed of 3.8MB/s and 6.4MB/s read speed. I have 10GB filled so far and It didn't really take that long to do. I'd say if you were filling the card up with 10GB of new music a day then yeah those speed suck but for a few big loads just to get it started no big deal to me.
I can stream a 800x480 AVC ~1.2Mbit off the card with no hiccups. So I'm not worrie about the speed considering anything more then that the processor becomes the bottleneck not the card.

Do you use your tp2 for music?
try playing a few songs in a row from the music tab with screen turned off...
I just recieved an A-Data 16GB Class 6 from ebay. Seems to be fine, passed memory test with no errors @ 8.9MB/S write and 15.1MB/sec read.
Worth the money just copying video and music files to the drive via pc. Way faster than my previous 8GB Class 2. Don't notice any real difference in the phone tho.

I had a Transcend 16Gb class6 that disconnected if I tried that. I had to reboot to get the card to register in the Phone.
Been out on the road for work all week using music over bluetooth and co-pilot 8 heavily. Working like a charm.....maybe i just got lucky.
I'm putting my $0.02 on the table on MicroSDHC cards. Basically for those of you that want faster data transfer on a larger card like an 8GB or 16GB MicroSDHC, it can make a difference but beware of brands that are not well known and their transfer speeds. The Class ratings on the MicroSDHC cards only apply to their guaranteed throughput rates and are NOT indicative of the actual speed experienced on the cards. I've seen some Class 2 Sandisk cards outperform Class 6 A-Data cards before which is a little scary.
Hello!
I want to buy new microSDHC card to my phone and I'm wondering which one is the best.
There are three priorities for me:
- SDHC
- 4GB
- minimum class 6
I found TRANSCEND microSDHC 4GB Class 6 and SILICON POWER 4GB microSDHC CLASS 6. Which one is better? Or maybe you advice something else?
THere is a lot of disscussion about this in this forum. Please search
Sometimes it's hard to find sth when does not speak the native english. Can you please give me the link to this discussion or just post the answer?

Thanks! I've already studied thread nr 1 and 3 and nothing special there. Number 2 is 16GB and 32GB - I need just 4GB and not for WM but for Linux (ext4 and maybe one fat32 partition on it).
well if it's a pda device then it's interface cant keep up with even the normal card speeds
so high speed cards only really matter when you have it connected to a card reader connected to a computer

So it's better to buy class 4 but 8GB that 4GB class 6?
i have not seen any difference personally between 4 & 6. so go for highest capacity.
i have used quite a few brands and all my cards now are sandisk. None of them have given me a problem.
most important thimg regarding performance is to make sure that its genunine. more than 85% of cards sold these days are duplicate.

I don't know jack about linux or 'rooting' onto an sd card, but if I were going to do it, I would make sure that I got the highest quality card available. I've corrupted my 16 G card too many times (mostly my fault, lol) to trust it for running linux off of it. Get something hardy that won't become corrupted, like if the device freezes and you need to reset it. My guess is that you're better off with a smaller card (like the 4 GB one). I'd stay away from a big one if you don't need it.
Basically, it's a huge PITA when your card becomes hopelessly corrupted and you need to back it up and re-format it. I imagine it's a nightmare when your operating system is running off of said card when it becomes corrupted.

That's right!
"most important thimg regarding performance is to make sure that its genunine. more than 85% of cards sold these days are duplicate."
what do you mean? TRANSCEND and SILICON POWER are genuine?
on my purpose,there ARE differences between class 4 and class 6 ,but there are to small differences in speed to pay the double price...I just using class2 Devices (on 3 PDA Phones,2 NDS and an PSP),i never felt there are to slow,yeah on PSP you really fell the difference between an MemoryStick Pro MkII and an Class2 Toshiba MicroSDHC,but for me personally it does not matter -the most of People buy Great Capacity Drives for Media Files right ? ....and Media Files like Movies,Mp3´s etc. running well on Class2 Cards!
Excuse me to say that...but SanDisk Sucks!
a lot of the Sandisk card have Chips from China
(i Don´t know on Class 4 or 6 Cards,but Class2 Card from Sandisk always have Chinese Chips....and there bullsh...)
Japanese Chips (like Cards from Kingston and Toshiba) are a lot better on speed and are a lot more reliable than Chinese Chips
I made my Experiences ,never by SanDisk....
just every Media Market have SanDisk- but that doesn´t mean there are really good..
I have Cards from Siemens,SanDisk,Kingston,Nokia,Toshiba and Motorola (Nokia,Siemens and Motorola are OEM- so i don´t know who produced them)) I have over 20! Cards between 64mb and 16gb---yeah and San Disk are the worst ..dood!
and there IS a Difference between Class4 and 6 Cards,but i think personally there are to less to pay the double Price for it
I have 3 PDA ,2 NDS and an PSP,all of them has Class 2 Cards and i never felt that there are to slow...most of the Devices on the market are to slow to feel the REAL Power of an Class6 Card!

well it was said that the samsung wp7 phones ran better than the htc or lg so i am not supprised. however we do not know if the focus also has an internal nand along the the external storage slot or a micro sd and this phone also ran faster so it still remains to be seen if its the sd card or not..
another reason for me to get a Samsung when they come to Verizon...
Maybe the htc will be faster if you change the sd cart with a higher-class card?!
Wow, the difference is huge.
The Omnia 7 is definitely a great device (and the HTC definitely disappointing).
What a pity the Omnia has only 8GB of storage. Otherwise it would have been THE perfect WP7 device.
Makes me wonder if the Focus will slow down if you put in an SD card. I would also like to see the HTC with a higher class card.

There are far too many unknowns in this comparison for it to answer too many questions. The fact that NAND memory is faster should come as no surprise, however, we have no idea what class card is used in the Focus yet or even what type of memory the first 8GB is. As for your additional memory, MS and att state that the phone will work for all classes, 2, 4 and 6. For 8GB and 16GB cards I know that the class speed difference is significant. I have never owned a 32GB card yet.
Thats a bit speed comparison.
The Samsung WP7 devices seem to be better than the HTC devices.

Your 32GB disk will be fine. I am guessing that it is a class 2. You meet the min reqs which MS has set. If it is a class four and you have tested it and found that it really is a class four, we are all dying to find out what the speed difference really is in the 32GB cards. If you are one of the owners of the elusive 32GB class 6 cards, don't sweat this at all and tell us who your source is.
MS's concern is card quality, not speed. There are still a lot of unknowns with the Focus, for example what type of memory the first 8GB is. Bottom line is that the combined memory will not be much faster if any than the slowest of the two as you have no idea where data will be written.

How fast the app will load will depend on luck until we figure out in what order WP7 fills memory--if the phone installs the app to the ROM, it will load significantly faster than if the phone installs the app to the SD card.

Erm, an unbranded card like that for such a low price is highly likely to let you down, personally I wouldn't touch it with a barge-pole. Stick with Sandisk, their products are more expensive and currently at class 4 but they're guaranteed and they won't make your phone cry.
I'm looking to upgrade the crummy 1GB SD card in my wife's TP2 to something faster. I was wondering if buying a class 10 card was worth it or if I should just stick with a class 6 or lower. Does the SD slot in the TP2 even support a class 10 card? Would a class 10 card be noticeably faster than a class6?
Not for this project. IIRC Nate said class 4 seems to be the sweet spot, the higher the class the worse it would be running XDandroid, but even some class 4's work better than others. Walmart has 16G class 4 sandisks for around $20, not too bad if you ask me

Cool. Thanks. So get a class 4 then? Is it worth it to get a 16 over a 8GB? My wife doesn't put much on her phone really and she streams all of her music.
Yeah I've got a Patriot 16Gig Class10 SD card that I picked up on sale months ago. I have been running XDAndroid on it since then and haven't noticed any benefit over my old 4gig class 2 card.
Not sure if it's related to running andriod but at first I was having issues with the card corrupting and losing all data on it, having to format it to be usable again. Formatting a few times with the HP tool seems to be helping.
I had a similar issue with my last phone (HTC Hermes) which would only work with good quality (Sandisk) SD cars, and failed with cheap chinese flash memory. The issue was that the phone wasn't able to remount the card properly in winmo when coming out of sleep, and the filesystem would become corrupt pretty quickly with folders disappearing and files having wacky filenames. Sounded like it was more of a hardware issue than anything.

Yea I use a class 4 card. Some have reported oddness with class 6, so it seems like the type of card matters as well... Because others with C6 cards say they work just fine. I've even had some people say C10 cards are fine, but most seem to have issues with C10 cards. Don't get some cheap knockoff, get a name brand.
As for size, that's entirely up to you. You can have up to a 32gb card. 512mb minimum .

Just don't get a C10 card... I think that's what people should take away from this.
Some have said C10 cards are fine, but most say they are not. A few have had issues with C6 cards, but most say those are OK. I've never heard of people complaining about C4 or below cards - hence the reason I recommend anything C4 or less.
c10 sd android
My company name is WinDroidz and all I do is mod android and windows devices... and I have always seen huge performance gains with c10 cards, c2 sucks major, its just the transfer speed the card can move data at and clearly more speed no matter how u look at it with an SD card. Is crucial... I always used patriot c10, or topram and pqi c6 cards for android SD on windows devices and have only seen a posative result.. this is based on my personal experience of Modding more Devices then I can remember.... not from what I read somewhere or was told by someone... SD card data transfer is the slowest method of data transfer of all other common used methods... there are graphs if u Google it that show sdhc c2 cards lined up against other transfer methods like USB, ide, sata etc..... to put in perspective how ridiculously slow SD cards really are, once u see that u will understand why your phones drags ass so much when trying to pull up gallery after cache has been wiped if you have a ton of pics etc.... so if u are having problems with a higher class SD its probly not the SD and is something else you are doing, or maybe the brand as I can only vouch for the ones I've used... (wouldn't care personally about brand as pretty much everything is same manufacturer with restamped brand and packaging.. Kingston is Japan... currently using a c4 Kingston 32gb in my desire HD (wish it was a c10 but kinda pricey for that size and brand) I recommend c10 8gb for $30 on Amazon if u are using some kind of android SD rom.. or any device if u want better transfer speeds and it is very noticeable... no matter what speed u get though it will never run like nand android.. like HD2. So lets just hope the nand development for other devices continues like clk or magldr did for hd2 cause the hd2 with clk and full rom manager support is amazing
16GB class 10
Using 16GB class 10 and have had no problems related to the card, with FRX07.
I personally cannot think of any logical reason why a class 10 card of good quality should ever be a problem.
I just installed and ran Angry Birds Rio. It is slow, but works. Kind of fun to play in slow-mo!
i use 8gb c6 and haven't had any problem so far.
My 16GB RiDATA Class 6 Micro SD has been great, no problems.
so, which would be the best, most stable class 10 micro sdhc card? i can't seem to find a definitive answer, as everyone seems to complain about the cards not being a "true class 10", etc. there are only a few reviews on newegg,
http://www.newegg.com/Product/Produ... 600006235 600082443&IsNodeId=1&name=Class 10
and amazon, a bunch of people complain about the speed ratings mot being true.

which one do you guys have experience with, and would recommend? the kingstons are just out of the question, as i doubt that they'd be worth twice the coin.
It would be nice if you narrow it down to specific cards.
Although there is to note that most people do not need anything past a class 4 which is more than enough to handle day to day transfer between phone and card.
Sandisk seems to be a darkhorse here since they don't really show you a class number and it ranges from 2 - 6 mbps. The best way is to simply test it out with a SD card testing program.
thanks for the response. specifically, i like the PNY and SanDisk, but like you said, sandisk is secretive about their speeds. i don't want to buy, test the speeds, and return if i'm not happy with it. and is class 10 not required for recording HD video on our phones? thanks again
nah, class 10 is not required to record HD video. besides if i remember correctly, the dz only records up to 720p. you should still be fine unless you're shooting a 20 minute video.
There are some reports from people with various issues with Class 10 cards. Its not widespread by any means (plenty of people here seem fine with their Class 10), but it seems that Class 10 have more issues than lower Classes. So some here will recommend Class 4 or 6 (can't remember which) as the highest you should get.
I'd stay far away from PNY if I were you. I've owned 2 PNY products. Not Micro-SD, but an SD card and a USB thumb drive. On the thumb drive, the USB port and memory chip pulled/broke right out of the plastic casing with regular use (not damaged in any way). The thing just looked and felt flimsy. But I needed one in a hurry for a business trip, and I bought what the store had. I figured, its a USB thumb drive, you can get these things for free. How bad can it be? And I was shocked when the thing actually broke apart after a few weeks.
Similarly, the PNY SD card I have split into 2 pieces (along its seams). In both cases (PNY thumb drive and SD card), the memory chip itself still worked fine, and it was just a matter of using some super glue to hold together the plastic casing that failed. But it just displays shoddy and cheap build quality. I own 3 Sandisk Micro-SD cards, and a couple Sandisk SD cards and thumb drives. Never had an issue with any of them, and build quality is much better than PNY.
There is a long thread in accessories with SD recommendations:

DUDE! I had the same problem with the PNY thumb-drive! It was the attache series I think. Anyways yea stick to well known brands that are consistently rated high, sandisk, kingston, adata, etc. Honestly though, class 6 would probably be the fastest you'd need unless your gonna be taking extremely high quality pictures at a very fast speed lol aka multi-shot. But then again I'm not sure our phone is even up too that anyways lol.
I have an ADATA 16GB Class 10 from newegg. Has given me zero issues. I would imagine this is probably the same for the 32gb version.
Not sure if the 32GB would hold up. I found out that I'm not that big of a packrat on the size of the SDcard, so I went with a 16gb instead of paying more for space I'd never use, or take years to accumulate.
h2testw 1.4 log after testing it out when I received it:
Warning: Only 15786 of 15787 MByte tested.
Writing speed: 15.1 MByte/s
Reading speed: 18.5 MByte/s
It was definitely a step up from the 4GB class 4 kingston I was previously using, which was getting write speeds of around 5-6mb/sec. After moving onto the Adata, I noticed speedier loading in the photo gallery like night and day. It used to take 2-3 seconds to load the gallery, especially if it was a big picture folder. Now it takes literally milliseconds to load the content. Of course, this may just be anecdotal and placebo effect, but my general experience with android and sdcards for the last 3 years is on the line about it.
actually i retract the kingston comment, i think they had problems with 32gb class 10 cards specifically now that i recall...

The Sandisk that came with my phone has the class 4 symbol printed on the card...
I'm thinking of getting a class 4 myself, don't feel like paying almost +100% for class 10. I'll probably get an A-Data, as it gives a decent price per GB. I'm just torn between 16 and 32 GB
As for Kingston, I think the quality of their products went down a lot in the last two years.

Its an old card. Sandisk used to designate Class, but they don't anymore.

If you look through the thread I linked on my previous response, you will see there are some folks that claim more data corruption issues with 32 Gb cards versus smaller capacities. It seems purely anecdotal. But my point is, don't assume.
My adata 32gb class 4 is going strong since august...
sooo... is class 6 good enough for games, apps2sd, recording HD video, etc?

For me I bought this off ebay ( http://www.ebay.com/itm/380405008880?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 ) and it has been working great for me. I loaded it up to about 28Gig and had no trouble. Currently I have 10gig free.
I've got the Sandisk 32gb class 10.
But the one from Samsung seems great.
The SanDisk 64GB MicroSDXC is also fully compatible despite the device being a sdhc device. Apparently the protocol differences lie on code and not on hardware.

Yea according to this article and many other phones on Gingerbread. I suppose there shouldn't be any problem under ICS.

well. that is fantastic.. Maybe when the prices go down in a year i can get that to upgrade my 32gb card.
