Ok, so I know this is a topic that has been really over-discussed, but I really can't seem to find very much good information online, so I turn to my most trusted authority...XDA with a few questions...
I currently have what I believe is a genuine Sandisk 16 GB Class 2 microSD card. And from reading in the forum - I realized when I upgraded (in the meantime I reverted back...) to CM 7.0.3 I had serious lag issues, and I understood from different posts that it was because I needed to upgrade the class of my SD card. In the interim, I've purchased a Sensation 4G (which I have yet to receive - but expect to have by Wednesday). I know this phone comes with an 8GB card - I'm just not sure of the class - but assuming that the phone records HD video - they should have the sense (no pun intended) to provide at least a class 4 SD card right?
Here's the thing. It's really hard to understand - even from reputable stores, which SD cards are real and which are fake.
General questions:
1) Why do some cards have their class marked on them and some don't? What does this mean?
2) There is no standard look to SD cards even from the same company. How can I know where to buy a real one?
I already got burned by eBay - so I'm not going down that route again - but even NewEgg and Amazon (where I bought this card from and am happy with...even though I'm no longer sure it's even real. I downloaded an app that's supposed to test read/write speed and authenticity - and it didn't say Sandisk, so now I don't know...Despite being a class 2 card with write speeds of higher than 6 MB... so I really am confused. I'm assuming a fake card would cheap out on quality...)
While I always prefer to pay a bit more for the best - and from what I can see there is no consensus regarding any SD cards besides Sandisk/Toshiba/Samsung, however - there are no SD cards from any of these brands to be found online for purchase with a class higher than 4 - besides class 10 that costs somewhere in the vicinity of $100 (which I am currently unwilling to pay).
1) Is there no Sandisk Class 6 or 8 card?
2) Why can't I find them anywhere if so?
3) What is known about companies such as Kingston/PNY/Lexar/Transcend - what I've seemed to find is that the good reviews are great - but the bad ones are REALLY BAD. Do I want to chance getting a lemon and losing something as precious as photographs??
4) What about reputable companies that aren't necessarily known for their memory/SD card strengths but other areas - Duracell, HP, Panasonic, Nokia?
5) Would I be better off downgrading to a smaller card with a higher class? (i.e. 8GB Class 10?)
I'm really confused - any and all help would be very much appreciated.
Thanks!!
Lexar class 6 16gb and all is well.

What are you basing this on? Not according to Amazon...only 7 reviews and three of them are terrible.

It's not so much the "class" of the card, but the real-world performance of the card. I've seen class 4 cards preform better than some class 6 and higher cards.

There is no way to tell a fake one from a real one by just looking at it. to be safe, buy one from a brick-and-mortar store, where it is easily returnable. Don't buy it online unless it is from a well established retailer like Newegg.

I personally would group all four of those companies you mentioned in with SanDisk at the same quality level, but that's just me...

As you said, they don't specialize in flash memory, so chances are their products would not be as bleeding edge as SanDisk/Kingston/PNY/Lexar/Transcend.

It depends!
I have been using a 16GB Transcend Class 6 card, for the past two years or so, and have had zero issues with it.
I also have a 16 GB SanDisk Class 2 card (although I don't use it in my Nexus One), and again, I have had zero issues with it.
I certainly would not put any faith in reviews on Amazon, etc. If anything, I would look at a reputable tech review site like tomshardware.com or anand-tech.com. Otherwise, buy and try, and if you are not happy, return it.
Wow! Major thanks for that reply! Was very helpful!
transcend class 6 is a great card. sandisk are also great.
+1 on the A-Data 16gb Class 6--great for a year now
Have read GOOD reviews on a Lexar 32gb Class 10

I have a SanDisk 32GB Class 2 card that I've been using for about 6 months. It's performing almost as well as the SanDisk 32GB Class 4 card listed in the CyanogenMod SD Card performance wiki table. Using the same testing protocol, I'm getting 5.67MB/sec writes and 11.28MB/sec reads.
Wintec 16 gb class 10 from Fry's. It performs like a class 8.5, not bad!
I bought a 11 euro 8gb micro SD class 6 with A2E in CyanogenMod 7 and runs like a charm .

At the moment I'm using a Kingston 8GB MicroSDHC Class 4 and let me tell you; IT SUCKS.
The speed it horrible comparing to my Sandisk 2GB Class 2.
Therefore I would like to get a Sandisk instead. They are pretty cheap these days online. Amazon is selling a Sandisk 8GB class4 for only $16 + shipping. However I'm from Canada, shipping is a monster. On Ebay, most of them are fake and not even Class 4. So do you guys have any suggestion for me on where to buy a "Real" Sandisk 8GB class 4? (well, no need to be Real, as long as it's fast)
I'm not sure about the sandisk class 4 I would try perhaps Amazon.com on that. But as for Micro SDHC cards go this is by far the best card for the price. http://www.newegg.com/Product/Product.aspx?Item=N82E16820208453 Just in case you are wondering it is a class 6 and I have this card personally and can verify that it operates at the class 6 specs.

Amazon.com and newegg.com doesn't ship microsd card to Canada.
As stupid as it sounds, newegg.ca doesn't have any 8GB microSD other than from A-Data... and I had really bad experience with that company.
That's strange that they won't ship them to Canada, but anyways I have used A-DATA for many years now and I have never had a bad experience possibly you just happend to get a bad product which unfortunately happens sometimes. I suggest A-DATA to lots of people and trust them myself so it might not hurt to try them again. Just my thoughts (man I feel like an A-DATA spokesperson LOL)
Edit: Just checked newegg.ca and found http://www.newegg.ca/Product/Product.aspx?Item=N82E16820208453 which is the exact card I recommended.

Have you ever use Transcend card?

Yes I as previously stated I have that exact card and have been very happy with it. I also have 4GB of their ram in the very computer I am typing this with. For more info on them check http://en.wikipedia.org/wiki/Transcend and make note of the quote "On September 2008, IDC India reported that Transcend ranked number 1 in sales of flash memory products, including USB flash drives and flash cards, in 2007, beating Kingston and SanDisk[2]."

I get about 6MBs write and between 9-10MBs read I just wrote a 1GB dummy file to it and about 3.5-4 mins.

My Kingston 8Gb Class 4 take about 4min to transfer 1GB as well. I find it slow. When I did a benchmark using PocketMechanics, the write speed is only 2MBs. That's why i'm returning it. Now that you're telling me it take you 3.5-4mins, I think my card is not that bad, then.
When you said 6MBs write, how did you test it?

The program I tested it with is listed there and I just took the averages sometimes it is higher very rarely is it any lower.
find a friend who works at futureshop or bestbuy and get them to buy you one. their employee's discount is sick.
Or, if you're in vancouver, check http://www.ncix.com. they sometimes have good deals. best of all, staples are sometimes willing to pricematch/beat them

Rank in sales means nothing if you're looking for quality. 90% or more of the time the top name in sales is NOT the best quality, just the best value. Sandisk is definitely better quality.
HTC HD2 - what size of MicroSd it can supports?
It supports the SDHC standard, so up to 32GB. Anything above that will require the upcoming SDXC standard.

Hi, I just wanted to ask a question regarding microSDHC cards:
Does the class of the card make that much of a difference (in terms of smoothness of video playback) ?
I'm not too bothered about write spead.
The reason I ask, is because I can't really find anywhere (I don't use ebay) in the uk (online) that's selling reputable 16gb class 6 microSDHC cards (that are in stock). Will class 2 really be a step down ?

Class does matter in speeds. So I would say yes, but you won't notice it.
I got a 16GB Micro SD-C class 6 and a 4 gb class 3/4 and video playback on my Touch HD is the same....

Any real difference between Kingston and Sandisk at class 2 ?
timewyrm said:

Click to expand...
Click to collapse
No, absolutely no difference at all.
The only time the class will make a significant difference is if you take the card out of the phone and connect it to your PC's USB port using an adaptor. A high-speed card connected like that can be written to a lot faster than it can while it's in the phone. But otherwise you're limited to the speed the phone can access the card at - which is a lot slower.
It's also worth saying that a class 2 card made by one of the better manufacturers (Sandisk, for example) may well be faster than a generic class 4 or even class 6 card - class 2 means it's guaranteed that you can write to it at 2MB/s or faster, but the ratings of cards from good manufacturers tend to be very conservative.
As for video, the bit-rate of a video file is not that high. My Touch Pro 2 maxes out at about 750 kilobits per second on an .mp4. The read-speed of even the worst class 2 card will be at least 2 megabytes per second - which is more than 20 times as fast. The Leo will probably be able to cope with higher bit-rates than the TP2, but certainly not 20 times as high.
That's just what I was hoping to hear
Thanks!

Don't HTC have an online store in UK? Here they have Transcend 16GB Class 6 cards in stock, although they usually charge more than anyone else for what they sell.
I personally prefer to have the fastest cards available simply because it pays off when you transfrer large amounts of data (music, video) via a card reader. Also, my older cards go to my digital camera where it is important.

My 16GB Nokia SDHC is playing videos with bitrate 2000+ & resolution 720x380 without any stutter.
I have almost 6GB full of videos only in my card.

He was specifically asking for the fastest card. Your card is the slowest. Class 2 is the slowest class you can get. It's not even sold anymore here in Japan. For the HD 2 I would recommend at least a class 6 card (6 MB/sec reading. The better ones are now rated as class 10.
SanDisk 16gb Class 2 exceed the speeds of asian branded class 6 cards such as Transcend and Adata etc.
I would get a Sandisk Class 2 16gb card over other higher class cards.
Only better one at the moment is 16gb Class 4 SanDisk which exceeds class 10 speeds.

Just because it is Class 2 does not mean it is the slowest!
The Sandisk Class 2 performs well above the majority of class 2 cards and even some class 6-8 cards.
The 2 only means it guarantees that speed.
I've seen some class 6 cards just reach 7mb/s, so this class 2 would run the spots off it. I've got a Sandisk 16gb Ultra Class 4, its quite fast but you need to consider the fact that the phone won't use it to its max potential, only 8mb/s limit i think
From what i hear the class definition only is a guarantee for write speeds.
http://en.wikipedia.org/wiki/Secure_Digital#SD_Speed_Class_Ratings
"SD Cards and SDHC Cards have Speed Class Ratings defined by the SD Association. The SD Speed Class Ratings specify the following minimum write speeds based on "the best fragmented state where no memory unit is occupied":[8]"
I've got a Sandisk micro sdhc 16 Gg. It's only a class 2, but i should say that it is pretty fast and I never had any trouble with it. Fast and safe.
I find it better than the Transcend or Kingston SD I tried.
I hope we can soon have a micro sdhc 32 Gb

Thanks for the very helpful reply.
Did you get all of your 21 posts by helping people out with this sort of useful info?
Thanks to the folk who have actually posted useful stuff though...
I see the Sandisk Class 2 16gb one on Amazon and other sites for about £30 - which seems pretty good. I found another thread comparing speeds of cards, and it seems the HD2 can't write or read any faster than the equivalent of a class 2 anyway.
I think the Sandisk Class 2 will do for the moment - the 32gb ones are due out anytime soon... so theres no point in lashing out £60 for a high spec 16gb when a 32gb will be round the corner.

I will be selling my 16gb when a 32 comes out, got it quite cheap so I can't imagine I will really lose that much money on re-sell as there are not that many 16gb class 4's about.
16GB Going to buy with my christmas paycheck. Anyone know of any good deals for SD(HC) cards in the UK?

ouch..£52.99 is a bit steep to justify when a similar spec standard sd is less than half that price..I can't help wondering whether there's any real benefit from a card with this performance level that's detectable in normal use,after all,the ammount of data that will be required at any point in time surely wont exceed the displays capacity even while using a lower spec card? Yes the snapdragon can process huge ammounts of data quickly but it's still going to be limited ,by the ammount of it,it can show or am I talking round hairy things? I've seen a similar debate on a forum dedicated to sat navs but never found, myself, any difference between using cl2 or cl6 cards as far as speed in the processing and displaying of information upon a screen goes...anyone care to enlighten us?
I have been using Sandisk Class 2 16GB cards for a while now, 3 pcs on separate devices and I can say it is fast and safe. Fully compatible with the HD2. I also have a 16GB Kingston Class 6 and it is about 20% of the Sandisk speed when writing. Way too slow even though it's rated as Class 6. Go figure.
Could someone reccomend a good 32gb micro SD card for the Hero. Please provide a link if possible.
Those out yet?
does the hero support 32gb cards?

I've read mixed reviews on the 32gb cards. I've heard people say that anything over 16gb isn't recognized by the hero. Don't quote me, just repeated what I heard and I don't remember if it was on XDA or someplace else where I read it, but I'd do a little research before buying one on whether or not it will work.
Having said that, the best microSD cards are probably Sandisk and Transcend. Your mileage may vary. I recommend NOT purchasing from overseas vendors...a lot of times you'll end up with a piece of junk. Amazon usually has pretty good deals, as does best buy, so I'd check there.

There's a little C printed on the card with a number inside it, that number is what class you've got.

Either a SanDisk or Transcend and it should be class 6 for the faster speeds.
Are these for real Class 4
are there any Class 6 yet ?

What is the largest, fastest and most budget-minded SD card I can get for this device, preferably off of NewEgg...
I can't remember if the largest "recommended" size is 16gig or 32, but get a class 10. Also, don't go to New Egg, go to Meritline.com, much cheaper on the micro SD cards, and problably even cheaper elsewhere.

So always get class 10 for mobile devices? I'm not looking for a recommended size, I want the maximum size.
Also, NewEgg has class 10's for way cheaper than the site you mentioned.
I could be wrong, but I just thought the class indicated the speed of data transfer, so I've always gone for class 10. And yeah, I never noticed the price gap being so marginal on class 10 cards between New Egg and Merit Line. I've always used Merit Line for any media related purchases. Monoprice for anything cable related (I will slap anyone in the throat I meet face to face who spends $60 on a 6 foot "Monster" HDMI cable at Best Buy), and then NewEgg for everything else.

Gotcha. What brands should I stay away from? What ones should I strongly consider?
Will a 32GB card work on this device?
I used a 16gb, but I cannot remember what the manual said would be supported. However, I thin microSD only goes to 32, I'd wait for someone else to chime in to see if they use a 32gb without issue. I've never paid attention to brand, and it's worked out for me.

Is PNY any good? Kingston and SanDisk are great in my experience.
I know PNY makes good RAM, but have never used their sd cards.

Kingston is great in my opinion.
Press Thanks if i hepled u
I use the "ADATA 32GB Micro SDHC Flash Card, with Adapter Model AUSDH32GCL10-RA1". It's a Class 10 device and I've had no problems with it and the A500. It currently is $63.99 at Newegg and $72.95 at Meritline (sorry fermunkey!).

How long have you used this card?
I'm using a Duracell 16GB Class 6 and it works wonders. Only cost me $25 from a brick and mortar store too, which isn't too bad. You won't notice a significant difference between class 6 and class 10 on any Android device, so personally I wouldn't bother with the added cost of a class 10 card.

I've been using it since the end of July. I've got multiple backups on it as well as movies, music, etc.
Jeff.
I am using:
WINTEC FileMate 16GB Mobile Professional Class 10 microSDHC Card with SDHC Adapter
available at Newegg only 19.99...get a couple!!
@jlary - +1 on the AData 32gb micro sd card. Bought my A500 in May and same day ordered sd card from the Egg. Has worked flawlessly ever since including all my attempts to brick my A500 lol. Got all my movies and music and pictures on it plus backups and roms.
I'm using a 32 GB in mine. I'm not sure of the brand, but it is Class 10 and it works well. (I keep my movie files on it and play them from there.)
I also have a adata micro SD card I got from newegg stressed to full and it did not fail been working for three to four months
Sent from my ICONIA
+1 for ADATA. I use a 16GB class 10 and I am pretty pleased with the performance.
