SanDisk Mobile Ultra MicroSDHC 16GB SDSDQY-016G-E11M
I had a new Class 4 16GB Micro SD Card delivered yesterday after one of my cards failed.
Speed was markebly improved over the old Class 2 cards I have. Data transfer was particularly impressive!
The card is a little pricey £££ and I could have replaced the faulty card with another cheaper Class 2 but thought I'd give the "Ultra" card from Scandisk a go.
I watch a lot of video (on the train on the way into work in London - Heroes, Battlestar Callactica etc !!!) and speed is important - especially for standard DivX with no additional compression! Any lag I had previously has now gone - Very impressed....
I ordered the card from Amazon - link below - and although it states 3-4 days for delivery it arrived next day.....
Here>>> Amazon.co.uk
ScanDisk Official details can be found >>HERE<<
.
Are you getting any skipping/jumping/pausing of music with this card? I would be interested to hear especially with your rom as I did get such problems with my class 2 16gb card and same rom (Dutty 2.3). I've just flashed my old Polaris to 3LIT3 VI Suite and am now getting the problems on this device which I never used to. Hence my theory about the card being the cause of the problem.
Will be interested to hear.
Thank you.
Wow, that is certainly impressive. I presume you're using CorePlayer to play the vids? And no lag at all? Awesome.
PS: To Galactica... best ship in the Fleet.
I've had the card for a few days mow and have just returned from London and can confirm that the video playback is greatly improved. I'm using CorePlayer - I used to get some ghosting (phasing) and the odd skip but now its very smooth indeed.
custardo01 With regard to music - I have never had an issue playing music so cant comment on why your experiencing a problem - I'd recommend copying an audio file onto the main solid state drive (device) and play from there to confirm its a problem with the card before purchasing a new one though?
Arthenik .....Galactica - Absolutely - watched the 2 hour final episode yesterday (on the HD) fantastic but such a shame its over!!!!
.
Well, I guess I'll have to get one too. I'm really impressed by your reactions.
Regarding Galactica, I watched the finale on air and then subsequently at a local Frak Party. Both times were frakkin' awesome. And yeah, I'll really miss the show a lot.
bench of new CLASS 4 SanDisk Mobile Ultra MicroSDHC 16GB SDSDQY-016G-E11M
Hello,
Could you bench the read/write speed of your card with a tools like SKTOOLS
It would help me a lot to make my choice.
Thanks

Palmde - I'll try to find some time this weekend to benchmark but as per previous posts I am very impressed - especially with viewing uncompressed video!
.
Thank's a lot for your help Blob8me.
I own already a SanDisk Mobile Ultra MicroSDHC 8GB and i am very hapy about it: I can watch most of my movies on my HD, without to re-encode them.
I hope that the 16GB version will be at least as good.
So I am waiting your results.
£38.99 including delivery here. They say it's class 4 ?
Just asking but where the hell do you need class 4 microsdhc?
class 4 means it writes 4mb/sec VIDEO to same place in card, so datastream stays healthy for camera usage for example 1080p HD CAMERA.
It doesnt mean it only works that slow. Our HD cannot even match those speed anywhere near. And second these phones do not use that kind of file management to save continuous file stream.
For example I have kingston class 2 and it writes 12mb/sec when using cardreader on PC.
Or example 2 so people really understands. There is SDHC card from sandisk which is Extreme III 30mb/s edition. That is only class 6 card. And it still writes as fast as 30mb/sec. Ive tested this and can confirm since I have those on my DSLR camera.
So question is why do you pay MORE for NOTHING?
Dont read class number, read what it writes and reads per second its what you want to know.
Edit: Ofcourse bigger class means it can be better but class number doesnt tell its real speed. since class number is for continuous data (video writing)

Hi All
Just ordered my new o2 orbit 2. Upgrading from my orbit 1.
I'm assuming it's still a tiny micro-SD card. Does anyone know what the largest capacity card that is supported by the orbit 2 ?
Jeff
how about something like ?
http://www.amazon.co.uk/SanDisk-Micro-SDHC-Adaptor-Reader/dp/B000VUPUOU/ref=pd_sbs_ce_title_3
Theoretically the HTC Polaris can support MicroSD up to 2GB and MicroSDHC up to 32 GB cards. Anyway in this moment the maximun capacity I've seen is MicroSDHC 8 GB cards (I've a 8 GB Sandisk and it works perfect), so don't worry...

Guess what you get if you search for 'memory card size' on the polaris forums ( advanced search ) ?
Sorry - no matches. Please try some different terms
It doesn't even pick up my new post.
I did search before I posted, always do. Sorry if you find it dull that i've posted a question that I could not find an answer to but that's what I thought these forums where for...
The 6GB card you linked to will be fine, and importantly it is supplied with an SDHC capable reader for the USB slot on the PC.
The Orbit 2/ Polaris can go up to a capacity of 32GB (if you can find cards this large at the moment they would be very costly) - 8GB are certainly available and I have seen 16GB is about to be released (might already be available, at a price) - Mike
MicroSD SDHC drawbacks?
Considering operation specifically for the Touch Cruise, are there any reasons to forgo (to do without) the additional capacity of the SDHC to gain greater than class 4 or 6 speeds (ie: sandisk ultra II microsd with read/write speads of 10/9 m/s)? Would these greater speeds help significantly with video playback or rendering pictures, or would one advise that the difference is negligible and definitely not worth giving up the excess storage potential?
I bought an 8GB Sandisk microSDHC class 4 (with microreader included) for 52 euros. Installed Tomtom Maps of Western Europe on the card and several movies (created with CloneDVD Mobile). Tomtom 6.032 as well as the movies played with Coreplayer 1.1.3 are running smooth. Hence class 4 should be fast enough.
Thanks
Appreciate the comment. I'll have to check out that clonedvd mobile software.
i bought an 8gb sandisk one on ebay for 45$. i was dissapointed though that the built in "all in one" card reader on my crappy ass dell xps m1210 laptop can't read sdhc. still a good purchase though, filled up to 6 gb so far with music and gps maps, etc. i do not notice any performance issues with sdhc.

The fastest speed of Sandisk MicroSd SDHC is class 4, wonder where you did find Ultra II?
Applications like Tomtom will run better (smoother) using a faster MicroSD card, the fastest speed I could find so far is Class 4. As soon as there is a faster card available I will go for it, as long as it is at least 8GB.
I've seen 12GB ones for sale. Would say TC can't use more than class 2, f/s video doesn't use that much!
There's plenty threads about problems recognizing 8GB cards tho, that suddenly it ;becomes; 2GB?

What do you mean with TC can't use more than class 2
The faster the accesstime to the MicroSd card the better the overall performance. If class 6 becomes available I will go for it
I am using a Sandisk 8GB SDHC cards which is a class 4 and it works fine.

I use the same card and I am happy with it, however, an application like Tomtom is depending on a lot of data transfer between the card and the application. I contacted Tomtom to figure out how to get a smooth working screen and the answer was, processor speed and data transfer speed of the card. In my previous equipment, a Mio A201 PDA, I replaced the 60X SD card with a 150X SD card and Tomtom run much smoother.

I thot it only affects sustained transfer. Burst/accesstime are something else.

I'm looking for a 16Gb SDHC card for my TP2. I have a Sandisk 8Gb SDHC which works fine, though occasionally slightly choppy video playback. I understand it is a class 2 card giving 2mbps, and there are cards giving 4 or 6 mbs (higher classes) but I'm not sure if those are for the postage stamp size SDHC cards.
Does anyone know if Micro SDHC cards exist higher than class 2? I was thinking this may improve multimedia playback and recording.

8GB class 6 is a verry common.
16GB are class 2 only for now.
I have 16Gb and I do not experience any lag in multimedia playback
I can confirm 16GB works perfectly. I use Sygic McGuider 7.70 on my Rhodium, and experience no lag in reading the maps or what so ever.
I don't notice any lag when reading maps using Co-Pilot Live 7. I've only noticed it a few times when playing back videos i've recorded on the TP2.
Perhaps the slight choppyness is during the recording rather than the playback.
Capturing photos seems to have a couple of seconds delay, so I wondered if that was just the camera application or maybe the speed of the card.
I see Sandisk have a class 4 MicroSD (Mobile Ultra SDSDQY-016G-A11M), but I haven't found a supplier in the UK yet.
No delays on my SanDisk 16gig job either.

Hi TheWizzard2203,
a little bit off topic: but: how did you manage to copy the mcguider sd-card to your 16 GB-card? On their homepage they say: copying is not possible.
Thanks for your help! (I think about buying McGuider, but this "no copying" is keeping me from buying it)

did anyone maybe bought the and tried them?
I never heard about those manufacturers before so I'm interested in the quality.
Micro SDHC Card.
Hi !
I have been testing a lot of different cards, and my recommendation is this
Transcend Micro SDHC 16 GB Class 6
And it has lifetime Warranty!
With kindly regards MacRoy
MacRoy, thanks for your post
I know tha Transcend and San disk are the leaders in this field but i'm interested in the above mentioned cards because they are the cheapest i could find on e-bay.
I would like to know if anyone has actually used them so they can tell me what is their quality?

Just purchased this one myself, waiting for it to be delivered. An 8 GB Class 6 Transcend card came with the purchase of my HD and it's been the best card I've owned so it was an easy choice for me. I wouldn't go cheap on something like this personally, you get what you pay for.
I bought the 16gb class 6 earlier today because my 16gb class 2 is starting to give me and my computer MAJOR problems. Up until now, the card has worked like a dream. I can't wait to see how much faster the class 6 will be like
i bought this card a few days ago
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250561131115&ssPageName=STRK:MEWNX:IT
waiting it to come...
i'm hoping it's gonna be delivered in a 2 weeks period so i'll give my opinion then on the card speed
the card has arrived....
by putting it in my PC the higgest speed I got was 5,2 Mb per second
I would like to make some more test so if anyone can give me some tool for testing the actual speed of the card I will report back with the results...

hello,
I bought the "Transcend Micro SDHC 16 GB Class 6" and since I can't flash any ROM, I formatted the card several times (FAT32) but to no avail,
you see the same thing?
Also this card is not compatible if you want to switch on Android.

my card is not transcend but I didn't formatted it when i got it... i just made a restore to defaults and once again installed all of my programs on it.. did you try that?
maybe you should format it with NTFS instead of FAT32?
but i don't understand why you said that you can't flash any ROM? did you try doing that already?
Looks good. Did you try copying 16GB worth of data onto it ? Some of these cards could be fakes and have lower capacity than stated.

I know youre all speed freaks - and youre talking about the class 6 cards...
But i just ordered this one (16GB, Class2, ~22$) (urgh - china product... - i never trust those *g* - but the price is just half of all i've seen before)
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270528336681
as the 8GB delivered with the HD also just was Class 2 i thought thats enough for me...
And it's just a third of the price for the class 6 cards youre talking about.
Actual my question is - what do we need class 6 for?
Don't missunderstand me - I don't want to flame anyone for buying class 6 - but in my case about 7 of 8 GB are static on the card (means i transfered it once to the card and it never changes - Music) and 1 GB is dynamic (new Progs and new Music,...) but even this doesn't change every day all at once but about 20mb every day (max).
So with class 6 we save some time on the first copy progress - agree.
And every day about 10 seconds.
I know the example above is just for me but I think it would fit for most of u *g*
So why all people are so keen on this class 6 ? (i ofter read about in this forum not just in HD section)
btw. the tested speeds of those cards - most are tested in external readers are they? Does our HD even reach them in USB mode? or even worse - in ActiveSync mode? Cause i don't take my card out every day to copy some files...
greetings
Edit: k some people might watch videos on their HD every day which could take a while to sync - but USB and ActiveSync quests are still out...
forgot the video thing - cause i just once watched a video on my HD half -> battery life is not made for in my opinion

it all depends on what do you need it for...
for me class 6 saves me a lot of time because i download approximately 10-20 GB of music a month, and somwhere about 20 GB of movies and tv shows...
so basically i transfer somewhere around 1-4 GB a day from my PC to my card...
true, if you're doing that through the USB or ActiveSync you probably won't see the difference, but i often don't have the time to do that so I use the microSD adapter and transfer it a lot quicker to my sd card than it would be done through the USB or ActiveSync
on the end it all depends on what you're looking for and for what price...
Class 6
From what I see, don't bother with class 6 16G. I bought one. Testing the speed on sd card is great but once it put it on HD, it's no different than my Class 2 8G. Could have just purchase a Class 2 16G.

Hi,
I just got an email from ebay asking me not to finalize this order because of problem with the seller.
It seems that this is a scam.
Be careful.
Bemi
the question is not "what is the fastest class 4/6 card" in my eyes.
I bought the HD with the standart 8GB.....class "dont-know"...
of course I thought following:
higher class,bigger card = more expensive than slow and small...
so I tried to find out which card is included....
I found NO information about it. there is nothing to find on the HTC site.
no seriuos information to find on forums...
and nothing "written" on the card itselfe.
so I thought about buying the best and fastet card (testet with real test equipment).....
BUT
because the card-speed is degraded by the hardware you try to read/write....
and there is not a single information to find about what a HTC HD can handle....
(I asked the HTC support and did not get an answer at all)...
I decided to DONT buy another card at all....
I see no advantage to buy the fastes card it the cellphone is not able to use it.
SO : Is there anyone here, how can say that it is worth to buy a class6 card e.g. ??
if : where do you got the information a HD can handle the speed at all ?
thanks

i bought the A-Data 16gig Micro SD card with two adaptors class 6 card off ebay for $54.99 and works great in my MyTouch 3g very fast and it has a lifetime warranty on also
So I ended up ordered a 32gb micro SD card off amazon without realizing the class until yesterday and it was too late to ship it. So I come here asking should this be okay for my TF?
I know the speeds will be slow but if that's all it is I can deal with it. My main concern is I have a lot of 720p & 1080p videos and I don't want them to lag. Will there be any lag when using this card, or should I just go ahead and return it?
Let me know if this has been asked or is in the wrong section. Thanks
That class doesnt have anything to do with read speed, only write speed. So a class two *should* be slower to write videos to it than a class four but read wise both should be much faster. Of course the actual speeds can vary by maker.
So, yes, a class two will be fine for playing HD video.
I've been using good quality (Sandisk) microSD cards Android devices for a long time now and *never* had an issue with them.
Remember the following:
1. The class of an SD card doesn't tell you how fast it is - it only really tells you how slow it isn't!
2. It only tells you the minimum sustained write speed in optimal conditions (i.e. unfragmented), and nothing about read speeds at all.
3. Good quality lower "class" cards can often exceed the class minimums for higher classes anyway. For example, I've several 16gb Class 2 Sandisk microSDs and in my testing can regularly achieve write speeds of 7MB/s with all of them.
Regards,
Dave
Cool, thanks a lot! If I ever get tired of the write speed I'll just grab another one later on down the line. Thanks again
Just to add my voice in agreement with the above posts:
Class 2 Sandisk cards are fine, even for 1080p files.
There is a lot of misinformation out there regarding Class speeds on microSD cards.
I've watched a 1080p high profile MKV with a video bitrate of 9500kbps on my Galaxy SII on a Class 2 card, no problems.
Heres my video showing exactly that:
Yep I've used C2 Sandisk and PNY cards without any problems.
I am going to buy the 32 gb Prime (with keyboard) and have been researching memory card options. I am leaning towards the following:
1. Lexar High Speed microsd 32gb Class 10 (for the device)
2. Sandisk Extreme SDHC 32gb class 10 (for the docking station)
I will use this to watch movies, play music, surf the web, take notes, use apps, and play emulators.
My only concern is I've heard the class 10's have trouble with speeds on smaller files/apps/programs. Will that be an issue? Or will these two cards be a good setup?
Pretty much everything will be "slow" on working with smaller files / programs due to file system overhead.
Doesn't matter if it's a class 2/4/10/1,000.

I've read similar things as well. You will truly be fine if you just get a Class 4 and save the money.

with smaller files (a few data blocks in size) you have as many writes to the file system management space as you do data block writes.
with large files there are much fewer writes proportionately which is why large files have higher throughput.

I went with a 32gb class 10 pny micro sd from newegg. It was 47.99 and I finally tested it last week. Wrote video/music files at 11.5-12mb/sec. Some of the other class 10s had reviews claiming they only wrote at class 4 speeds. I can't stand how slow my class 4 16gb in my phone us...
Hey cyi1 is there a chance you would mind testing the write speed using your phones sd card too just to get a view of the speed difference from class 10-4?
Thanks in advance if you can. I'm sitting here trying to decide whether I get the 32gb class 4 or the 16gb class 10 as they are about the same respective price here.

I second that, would like to know this aswell. please let us know.
You might want to give this a read.
I'd also suggest getting SD cards from a source with a good exchange policy. The speeds can fluctuate wildly within a class and even from idenetical cards from the same manufacturer.
So, what ever cards you get, test them and if not-acceptable, exchange them.
I stated this in the "Ultimate Accessory" thread. But I'm going to say it here to.
Don't buy the Patriot MicroSD 32GB Class 10. It's awful and I'm not the only one stating this. It used to be $100+ (I bought it when it first came out), but now it's like $40 because people realized how crappy they are. Speed throughput was never the problem, but they randomly corrupt and when it DOES happen, it's bad. Mine corrupted on me 3 times in only a few months. Each time I was lucky to have had a backup (Ti Media Sync) and managed to save just about everything. The first time I lost a lot of pictures that hadn't backed up yet.
Anyway, the corruption doesn't come from using USB or anything. Everytime mine randomly corrupted, I was using it away from a computer or charger. First time I was watching a video off the card (admittedly porn) and the second time I was taking a picture. Third time I don't know because the phone was in my pocket in standby and when I pulled my phone out to show someone a pic from the phone it wasn't there, along with the rest of the stuff that was on the SD. Oh, and the first time this happened was on my Nexus One, not my Sensation.
Anyway, I replaced it with the Samsung 32GB Class 10 (bought it for just over $80) and it's been rock solid so far (2 months in). Speeds are pretty much identical to the Patriots. I use "Boot Manager" and dual boot a couple different ROMs off it, and they all fly.
Just wanted to give you guys a heads up.
I went "cheap" on a class 4 Transcend 32GB for both my photon and my upcoming Transformer Prime.
In actual copies, I was seeing in the 6-7 MB range so I won't complain.
I purchased the ADATA 32GB Class 10 from NewEgg and it works wonderfully. I haven't done any testing beyond copying 4GB of video files to it, which copied at a rock solid 17MB/s! I'm impressed needless to say.
Model AUSDH32GCL10-RA1
Could you run a crystalmark benchmark on your card(s).
If the transcend random 4k R/W speeds are decent, that may be the ticket for me.
Thanks

i can, but I won't get to this until Sunday when i get home.
6mb/second was not on random writes, it was on bulk copies of mp3 files for the phone

no problem, and no real hurry (since like others in the holding pattern to actually get a prime).
My wife's xmas gift of a new camera is getting a SanDisk 32gb class 10 "extreme" (SDSDRX3-032G-A21) that I plan on running crystalmark tests on next week.
I might even hold off getting a micro sd until 64gb cards drop closer to $100 ... (e.g SDSDQY-064G-A11A might be killer at ~$100)

Attached are the results... It's just under 5 in sequential mode...
I was also wondering this. Will there be any difference in watching a video file (1080p) between class 4 or 10?
Large video files will be skewed towards the sequential mode -- which tested @ 20MB per second. That's 160Mbits / second.
In theory, this class 4 card could playback a maximum bit-rate blu-ray iso without a problem. Blu-ray maximum bit rate is 48 Mbits (or 6 MBytes) / second.

Class 4 vs 10
Unless you are recording HD video to the SD card, class 10 is a BIG waste of money. The class only refers to the write speed, NOT the read speed. If you are just loading videos or music onto the SD card, then even class 2 will be fine. It may take you longer to load the original files to the card, but it is NOT going to be slower in reading the data compared to class 10.
These class ratings are really needed for HD video camcorders and high FPS (frame per second) cameras that demand high bit rate & speeds. I use a 6 for 720p video on my nikon dslr and for 4-6 fps 14 megapixel shots, but class 2/4 for my phone/tablets where it is just used to store movies, songs, pictures, etc...
I just picked up 2 Samsung class 10 32gb Sd cards from fry for $35 a piece. I think it was a wise decision and will help me out in the future. I know it's overkill but I think for that price it was worth it. So now my Prime will have 96gb of storage when I hook up my dock. That is truly overkill as well, but who knows when I might need all of it lol.
After a huge thread I read here about classes, I changed my mind and went with a class 4 for the Prime (was thinking I mist get a class 10). I picked a Transcend 32gb class 4 off of Amazon for $33 delivered.
