So I plan on picking up the Epic next week. I've seen in videos that it comes installed with a 16gig Class 2 (pretty slow) microSD card. If I were to replace this with a class 6 microSD card, would that speed up the phone at all?
thanks!
Edit: Or a class 8 or 10 card. Is there any reason to think 1. there would be any incompatibility and 2. that it would help the overall speed of the phone?
There is no class 8 or 10, and no, your phone won't be much faster at all with a class 6.

The former is just not true, which a simple Google search could have told you. There's no class 8 AFAIK, but there is definitely a class 10.
Now...will it make your phone faster? For certain things, perhaps. Loading large thumbnail images in the gallery, taking pictures, loading applications installed to the SD card once we get Froyo, all will likely be made faster. However, in terms of value/money, I wouldn't recommend it. There shouldn't be any incompatibility, however it won't improve the overall speed of the phone (which really shouldn't need any improvement), only a few very specific tasks that access the SD card.

You're ignorant!
I have a class 10, and it won't speed up your phone unless you have your apps installed on your card.

Between the stock class 2 and the class 6 that I bought, I didn't notice much app speed difference on my Nexus.
Read/write speeds were better when taking pictures/loading files however.
Ok let me clear this up...1 yes there is a class 10 (going for like almost $100)
now as for the difference...Class only gives you guaranteed Minimum Speeds once the card fragments.
Normally most cards do about 16mb read/8mb write..BUT once the card starts to fragment with data like your HD your speeds will go down. A class 2 card guarantees you that it will be no slower then 2mbps..a class 6 card guarantees you it will be no less then 6mbps.
Now why is minimum important? well when your recording things like HD movies or etc and it fragments you don't want your movie to stutter.
Considering though max our phones can do is 720p at this point a class 10 is pretty much useless...a class 2 is ok if you plan to use it for storage(and minimum deleting) or not use SD card often but want to have it available...examples class 2 for songs is ok.

A little harsh? Nahhh, of course not.
Yes, there's a class 10, there's no class 8.
I would love to get a 16GB class 6 for my Epic, but $80 bucks is still a bit too steep for my tastes.

do a search on the vibrant forum - someone posted the results of speed tests on the different cards by mfgr and surprisingly, sandisk's class 4 were incredibly fast, by a factor of 3 or 4X over cards that were rated much higher
the Kingston class 10's performance was a joke, iirc - performed iirc, something like a class 4 or class 5 (if a class 5 existed)
now for the down side - the sandisk class 4 cards are (or were hard to find) about a month ago - it might have changed now. But i bought two, one after the other and both showed up, and they were marked class 2. One of the outfits, Kompubuy on amazon, showed the class 4 card and the appropriate model number. what they shipped was a different model number and it was class 2. When i queried them on it, their response was "sandisk had a typo issue some time back" - there were others reporting the same issue with kompubuy
second card from a different vendor, even though they confirmed what they had were class 4 marked, shipped correct product model, but card in package was a class 2. So i called sandisk and got the run around - the tech would not answer the simple question "are you telling me that cards marked class 2 are running class 4 speeds???" - he kept obsfuscating the answer. I suspect the class 4 cards are selling like crazy and they're or were overstocked with class 2.
their class 4s btw, were testing at 15 - 18Mb write speeds where class 4 is supposed to be 4Mb
when i tested the sandisk cards marked class 2, write speed was, iirc, about 5-7 Mb, which is surprisingly fast for it's rating. But that was in line with the speed testing others had done. The sandisk cards are way under rated, speed rating wise
in actual useage, folks weren't noticing much of a difference between class 2 read speeds and the higher classes - i believe the class speed rating becomes more critical in the write mode, which, practically speaking, isn't much of a factor on a phone
search for the thread and you can read the results for yourself

I saw the "TOPRAM" brand of card for around this same price, but I'm not willing to buy offbrand/noname SD cards because I'm terrified of card failure.
And larryccf, that is very interesting findings! I am very wary of buying SD cards off Amazon, specially when its not from a trusted seller! I was actually looking at cards from the "kompubuy" but I'm going to avoid them.
I think you get what you pay for when it comes down to it, which is why I usually only buy Transcend memory cards which I've had nothing but positive experiences with, and they do actually backup their "lifetime warranty".

I agree totally - in this case, both Kompubuy and the second vendor, were sandisk authorized dealers -
but i did confirm, using my "google fu" researching, the sandisk cards are much faster than their stated ratings. For the time being i found and went with a class 4 8GB sandisk card, figure i'll wait till the supply shortage peters out and get a 16GB card then

It is not a surprise that a class 2 can be as fast as a class 6 or 10...neither is a class 4 suppose to be 4mb...read what I wrote above..Class stands for MINIMUM SPEED..not maximum speeds. When you buy a Class 2 card you are guaranteed that no matter what it won't run slower then 2mb/sec in consecutive read and write...for a Class 4 its 4mb/sec...A Class 10 is not suppose to be faster then a class 2 card..it only means that the slowest speed the class 10 would go at is 10mb/sec
Long ago advertisers used to rate cards with things like 133x similar to how we have on burning CDs..those are MAXIMUM speeds.
i realize that - part i didn't realize was how much the sandisk outpaced the other makers cards, and the fact the kingston didn't make it's class rating

I wouldn't exactly say Sandisk doesn't exactly out pace the others...can you give me the link to the benchmarks?
Also Kingston has never been known to make good anything...that said it should make its class rating..if it does not the it possibly a fake...by fake I mean there are cards which fail QC and are destroyed but people steal those and sell them as branded cards..They are required to meet class rating no matter what..it wouldn't pass QC if it didn't

I feel I'd be remiss if I didn't share my Kingston story. About 8 years ago I bought a Kingston CompactFlash modem off of eBay, and it was DOA, but Kingston backed it with a Lifetime Warranty.
I called their support line at about 6:30 on a Thursday evening (Central Time), and a little before 8 the next morning the FedEx guy was handing me a brand new replacement. I didn't even have to secure the cross-shipment with a credit card!
I've used a few Kingston cards and RAM modules over the years without any particular impressions one way or the other, but the way they handled this problem made a lasting impression on me.

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.

Exactly 32GB MicroSD
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 ?

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!
Anybody now when 32gb cards will be available

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.

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.

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.
Looking forward to finally turning my phone into my day-to-day mp3 player, as well as running debian and apps2sd, I've been reading all the latest threads about sd cards and finally decided the most optimal config is a 16gb class 4.
Reasons:
· Class 6 is unnecessary as the nexus wont really take advantage of it.
· Class 2 may be kind of slow for apps2sd and debian, which I'm looking forward to investigate on.
· 16gb because although 32gb is comming, it will probably be too expensive for me.
Benchmarks:
I've looked through eBay and found a few interesting "offers", both at about $40:
SanDisk 16GB Class 2
TOPRAM 16GB Class 4
I really want a Class 4 for all I've been reading lately, but I can't afford a 16GB Class 4 SanDisk.
Does anyone know anything about "TOPRAM"? I had never heard about it before and I'm wondering if it could be a low-quality card.
Any help will be greatly appreciated.
No one knows ANYTHING about TOPRAM?
I've seen ppl complaining on the internet about the device not recognizing the sd card, but i guess that happens sometimes..i think..o.o

With all the talk about SD card speeds I've been seeing lately, I was starting to regret buying the SanDisk 16gb class 2 and not getting a Class 6. But after looking at this chart, I can't imagine why I would need more speeds than that?

I'm using a Polaroid 16gb class 2. Seems to be working fine for me, even running apps2sd.
I have an 8gb class 6 from RiData. seems fine to me, used on my MT3G, HD2 and now my N1.
i do agree with you though that a 16gb class 4 might just be the best cost/performance
Since we are talking about storage memory, I have a slightly unrelated question. Which is the better, microSD or internal storage that comes with some of the phones out there? In terms of speed, reliability, and cost, which one is better?
With regard to Class 6 - don't write it off if you plan to remove the card from the phone to do movie or music transfers. There are a lot of microSD adapters for computers that can exceed the performance of a Class 6 card and so if you are commonly hooking it up to a computer to transfer media then you'll be glad you went with a Class 6.
Now, if the capacity gets high enough to store all of my music, then I won't care about that issue, but personally I can only store a subset of my music on my microSD card so I do worry about the speed when attaching it to a computer...
i have that TOPRAM sd card on my nexus one i got from amazon Usa and it work very well
Class2 is definitely slower
I've used classes 2, 4 and 6 in an HTC Magic. I used apps2sd with Cyanogen Mod.
My own experience was that Class2 was definitely slower when using apps2sd. But Class4 and Class6 were better...and didn't appear to be much different. I had Class6 sdcards anyway as that is what was recommended for most of a year. They performed well.
The last ones I bought were Class 6 8GB Transcend MicroSDs for NZ$40 each (US$28-ish). That included 12.5% GST.
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.

I am basing this on real life, not amazon reviews.
Edit: what is it 7 or 3?

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.

None of the manufacturers are consistent with their markings.

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.

Why makes you think those brands are the best??

1) Not sure, but I'm sure if there is, it would be listed on their website, or one of their CS reps would know...
2) Call the company (or look on their website) to find out...

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
Probably my next card
Here is a nice chart showing speeds of various classes/cards

+1. Works great

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 .
Hey,
I am just flashing Windows Phone 7 on my HD2 now... I buyed a "Class 10 16GB Card" from a German Reseller (Media Markt) today. But while Im flashing using DFT I just have a Speed from 61 kbytes/sec... I think its not that fast, is it? Have I buyed a "fake class 10" card or something? what do you think?

Than Ill just go to MM on monday and ask for a refund. I will get one
just started again - was copied over in 1 Minute ca Works great But still some kind of slow
I have both 8GB class 4 and class 10, after 1 week using, Class 4 still best for WP7. With Class 10, I got restart many times
lol this is dragging up some old threads!
righty, quick SD card lesson
WP7 needs quick 4KB RANDOM writes/reads there are various threads showing you want seems to be best
Now, Class 2 and Class 4 have slow sequential speeds, compared to class 6 and 10
The class system is defined by srquential speeds, this is useful info if your using it for a digital camera, the higher the class rating the quicker you can read an write those large files
However windows phone 7 doesnt mess about with large files, it needs to access many smaller files in a random order.
Now, They way in which SOME SD cards get higher sequential speeds (and thus a high class rating) is by working some magic, unfortunately this same magic has a side effct of reducing random access, so the general rule of thumb is this
Class 2-4 will give you a higher CHANCE of working
Class 6-10 will give you less CHANCE of working
I say chance because apart from some PNY class 2 cards there are not any cards out there on the market sold as "high random access speeds"
Its luck, pure an simple, a Sandisk 8GB class 2 might work for one person, but not someone else, the reason for that is almost every card is made differently.
So statistically you will have better luck with a class 2 or 4.....
When moving to Yuki-Xbmod Mango rom I had 4 SD cards
16Gb Transcend Class 4
2Gb Sandisk Class 2
4Gb Kingston Class 4
4Gb "No Name" Card
The "4Gb no-name" card was the only one that worked.
I needed at least 8Gb and I didnt want to buy one and take teh risk so after asking my friends and trying there cards I found a "8Gb no-name card" that worked and had no choice but to swap my 16Gb card for a 8Gb card!!
My experience shows no-name cards work better.
