microSD speeds - EVO 4G Q&A, Help & Troubleshooting

I seem to remember something about the previous htc phones that they could only access a microsd card at class 2 speeds. Is this true of the Evo? I am getting ready to order my 32GB microSD card and I don't know whether to get the class 2 Sandisk one or the class 4 Kingston one.

I presently have a class 6 16GB in my EVO. But I actually thought that 16 was as high as you could go.
BTW... I dont see a huge speed gain going from my class 2 8gb to class 6 16gb... so it may be worth it to stay with the slowed speed since the price is cheaper.

Thanks for the info. According to the htc site it can take a 32GB microSD card. There are a few merchants that sell them but they aren't cheap.

16/32gb microsd - where to buy?

I have a HTC Desire and im after a larger storage than 4gb included.
I'm a bit wary of class 2 cards in fear they will be very slow. And I'm also wary of fake cards on ebay for example.
Also does class 4 vs 6 make a large difference?
I want a 32gb if its the right price (and not class 2?) but im not sure where to buy from. The site must be able to ship to new zealand.
Thanks.
I know that Verizon is supposed to be selling 32GB microSD cards, not sure about the class but I don't think their class 2. There normally $150 but have been on sale for $99 at least 1 or 2 times. So even if it is a class 2, still better than the $199 price for the Sandisk 32gb one on Amazon. Either way good luck, I hope you find the card your looking for!

I bought a 32gb from http://www.jr.com.
Seen the verbatim 32gb mSD class6 at amazon for 89$/free SH, and seen the 16gb's from 25-60 depending on brand/speed
Hey just wondering,where are you getting info on the micro SD cards? All I have found so far says 2 is faster than 4. I'm not saying I'm right your wrong but I just purchased a class2 today under that assumption.

lol. that is regular sd card not micro sd.
There is not a 32gb class 6 micro sd card on the market as of today.
Yeah, class 4 is about twice as fast as class 2 cards. I would say the best price/speed ratio right now is the Kingston 16GB Class 4 MicroSD card. Best places to buy micro sd cards online would be Amazon and Newegg. There's hardly any bull**** with the products on those 2 sites.
Amazon UK - You've now got 32 gb class 6 micro sdhc at £88.00 link class 4 at £85 link . I just ordered a class 2 for £64.49 including postage - link
Hope it helps.
Uhmm, a bit of confusion in my mind, wich class is enought for my Galaxy S?
The 'class' rating on the card can basically be thought of as the tested minimum transfer speed (sustained - not random. A random write can far exceed the class rating).
class 2 (~1Mb /s)
class 4 (~2Mb /s)
class 6 (~3Mb /s)
and the highest I've seen is class 10 (~4Mb /s) which I doubt any of us are going to buy.
So far as I know, there is NO CLASS 8 - don't buy one, it's probably a fake. By the way those ratings are in mega bytes not mega bits if you need the bit speed just multiply by 8.
Now if you're ever told 2 is faster than 4 you can laugh in their face - when (dealing with technology) has a lower number ever been better???

I meant to answer this earlier but any class would be more than enough for the galaxy s. The reason you want a higher transfer speed is that loading 8, 16, or 32 GB of data can take forever depending on the type and amount of data. As far as the phone is concerned, a class 2 is fast enough for a swap file, video/movie, or music.

I agree, the phone is going to max out before the card does.
Hey gang. I am new here. I just purchased a 32gb card class 2 for my Samsung Vibrant. I noticed it handles just about everything except recording hd video directly to the card. The first few seconds during playback show as rainbow colored garbled pixels then clears up to play clearly. Reduce the recording resolution of the video and it plays fine. Record hd video to phone then transfer to card and it plays fine. It is a brand new card (kingston) with next to no data on it so far. Anyone else having this issue? I am thinking I need a card with a higher class rating.....

To record HD video smoothly you are gonna need at-least a class 4 and maybe a class 6. Class 2 doesnt write fast enough to keep up, thats why you had the pixelation distortion.
As far as a 32gb class 6 card, I am afraid we are out of luck until these cards come onto the market. Samsung has been working on a new card I heard.
Hoever, newegg does have class 4 cards in 32 gb for around 100 bucks.
Hope this helps.
UPDATE
there is a class 6 32 gig card I found at amazon but it is a "Komputerbay" brand so buyer beware.

Who knows good places to buy memory cards in EU?
Hello. On ebay 32 gb class 10 is maximum 50 dollars, 16 gb is max 27 dollars. But i dont trust if they are real or fake. You know, they make Samsung's, sandisks fake and no clue to understand if it is like that.
So, where is best to buy, cheap and safe? Amazon, ebay?
And what brand, kingston Samsung, Sandisk?

Class 10 Micro SD Cards

How come only class 10 Micro SD Card I can find are Kingston brand? on Newegg.com review said it has horrible write speed although it is a class 10.. Can anyone point me to the right direction on best class 10 micro SD money can buy? (16gb at least)
I don't mean to be a jerk, but, do you really need a card to move data that fast? I mean I'm all for speed but really, don't sweat the class ratings so much.
Yea, I spent $100 on that Kingston class 10 16gb micro sd and I was severely disappointed. I think the problem is that the phone doesnt need to read and write data that fast. It makes caches of all the pictures, album info and art, and anything else if needs.
I spend $53 on the San disk 32gb class 2 micro sd and cant tell the difference. So now I'm using the 16gb as a flash drive for my key chain.
Where did you find a 32GB card for $53??
I think he might have gotten it when Verizon screwed up there website and had it for sale for about an hour for $50.00. That is how I got mine for $50.00
Verizon's online store the 1st day they listed it. They were supposed to have sold the card for $150 to anyone, $99 to people buying a droid x. Well, they dun goofed up and someone listed it for $49. I think its still listed for $99.

Reliable 16 SD card?

Since the 8 gb card that came with my DHD is a little too small I'm looking for a 16 gb sd card.
I browsed through amazon's selection and found many bad reviews regarding data loss on several products. What brands are generally known for reliable SD cards? Sandisk seems to make good cards?
And another thing, I read that often SD cards are faster than their class. There were people that got transfer rates of up to 15 mb/s with a class 2 card. Apparently a class 2 card is basically the same as a class 6 card, just that in the latter case the manufacturer guarantees the higher speed while in the former it might be slower. Is that true?
As for brands, I recommend SanDisk and Lexar. I've used cards from both manufacturors in all my cameras and phones for years, and I've never had a card fail me.
I got 2 Lexar in camera + phone : no problems so far
+1 for SanDisk
The Speed Class Rating is the official unit of speed measurement for SD Cards, defined by the SD Association. The Class number represents a multiple of 8 Mb/s (1 MB/s), and meets the least sustained write speeds for a card in a fragmented state.

Wikipedia quote
If I understand it write, the class rating is a sustained speed, so you may get faster speeds, but usually not.
Also from that same site, manufactures quote speeds, and not an independent testing company, so they may not always be honest XD
Secondly, Sandisk for 16 gig never gave me a problem. However, at 8 and 4 gig pny hasn't given me any issues either.
i wanted a bigger card a month ago and looked at both lexar and sandisk 16gb, i went for the lexar as it was apparently faster in the reviews and was only a tiny bit more expensive than the sandisk. and it has been perfectly reliable.
Ok, thanks.
joememe, which reviews did you read? I found one lexar vs sandisk at nokiaguide.com and just want to make sure we don't both base on the same review.
Because if lexar really is better I'll spend the few extra €.

That's interesting and a good thing because standards like S-ATA 1/2/3, USB 1/2/3 and many others define the max possible transfer which isn't very userfriendly.
So I suspect that all cards of a manufacturer are essentially the same and get a class 4/6/10 rating after production according to their QA results. Like with a CPU you might get lucky and the card just barely didn't make it to 10 and thus get a very good performance class 6 card.
I ordered a 16gb class10 Transcend card from Newegg and LOVE it. Lifetime warranty ftw!! I've tried returning Sandisk cards for warranty and haven't received a response in months...so not +1 for Sandisk if there are warranty problems.
I just picked up a Transcend 4gb class 6 micro sd from Newegg and it died within a day. Luckily Newegg is shipping out a replacement asap and I don't have to return the defective card.
+1 for lexar 16gb class 6
Here's a link to the one I use. I own 8 or so of these and use them in cell phones, camera's, and even in a cam corder. I have yet to see one of them fail or have any sort of performance issues.
SanDisk 16 GB Class 2 microSDHC Flash Memory Card
Note that even though it's a class 2, in my testing with each of the cards I own, I have consistently gotten class 4 performance from all of them.
If you want something even bigger, the 32 GB cards have really come down in price. Here's a SanDisk for $71.
SanDisk 32GB MicroSDHC Card (SDSDQ-032G-A11M, US Retail Package)
Isn't the price a bit too low? The one on Amazon has a bad review saying it didn't come in the retail package.

IMO, Sandisk is definitely the best choice for a quality microSD. They always perform much better than their class rating. And the also are most consistent in getting good randon read, write and access speeds, which is much more important that the class rating when using the card in cell phones or for any task other than just large data transfer and digital cameras. Higher class cards only give higher sequential write speed, but usually are worse at random read/write speeds and access time than a class 2 or 4.

Yeah this one, or a lexar class 10 if you want high transfer speeds with your pc.
Or a sandisk class 2 if you dont care about recording movies to your micro sd card.
the sandisk 32gb class 4 will work good with 1080p recording ?
and where i can buy it ?
because on amazon.com i can't find the class....
thanks
When I bought the Samsung WB2000 / TL350 compact camera which recorded 1080p @30fps it required a "Sandisk Extreme"... It apparently has a 20MB/s write speed. No class written on the card though...I think it's class 6 as class 10 is 30MB/s.
I would have thought you'd need a higher class to write HD video...
Note: "Sandisk Extreme" is a SD card not a Micro-sd

There is no class certified for 20MBps or 30MBps.
Class 10 = 10 MBps, thats why is 10.
So class 6 = 6MBps, class 4 = 4MBps, class 2 = 2MBps.
Class is equal to the minimum write speed in random spaces.

No, Class is the minimum write/read speed in sequential. The Lexar Class 10 32GB only does 0.018 MB/s in random write!
any more answer that might help me choose a good card ?

You need to figure out what you need in terms of speed and size, then how much money you want to spend. A 32GB class 10 card is extremely expensive, where a 16GB class 6 is around a third of that. I plan on using my Galaxy S II for holding all my music and some movies so I ordered this yesterday: http://www.newegg.ca/Product/Product.aspx?Item=N82E16820208573. Not too expensive and fast enough for most things.

as i said
i want 16gb but don't know which class and brand to take...
my main concern is recording video in 1080p
I have a class 10 Lexar 32GB Card.
You should buy a brand name card (Sandisk, Lexar, Kingston). I say that because there are IN GENERAL more reliable. There will be cards that are made by lesser known brands like Patriot and A-Ram but that does not mean they are any less reliable but more faults are reported for them than with Sandisk, Kingston or Lexar.
Having said that, my previous card was a 16GB Class 6 Patriot card. Worked awesome for a whole year and is still working in my friend's Desire (gave it to him and got the Lexar card for more space). In conclusion, don't buy eBay cards is what I'm trying to say.
Class? That's been debated A LOT. I got a class 10 and I can clearly see the benefit. Media Scanning is less than 10 seconds (mind you, I've got close to 38gb full in both internal and external cards), file copying is very quick and gallery files show up quicker, when I seek in a video file, it moves instantly (even with a 1080p movie).
It just depends on what you require. If you're slightly more patient, you can save 30-40 bucks by getting a 32gb class 2 card instead of a 32gb class 10 card.
Hope that helps. I recommend both Lexar and Patriot. Go for class 6 at least if price is not an issue.

Suggested Memory Card

Hey there, I've been using my Galaxy S2 for several months and never got to buying a memory card for it.
What you guys think is the best of the best?
How much GB?
Which manufacturer?
Model No?
What to look for when purchasing one on ebay?
Thanks!
just got a adata 32gb class 10, had a sandisk 32gb class 4 but its worth having a class 10 in it.
the R&W speeds when transfering data to pc is alot better and when taking pictures.
read 19.6mbs / write 13.2mbs with sdtools,had the same brand sd card before and was happy about the performance.
always use H2testw v1.4 just to be sure,it was the cheapest brand for its class locally.

I have a Kingmax microSDHC 32GB Class10 and I am very satisfied.
I tested it with SD Tools and got 9.1 MB/s writing speed, but in practice, it can go over 10 sometimes, but also can go lower to 3 MB/s and such.
I recommend this card, as is not very expensive either.

Good choice! I also bought a class10 32GB SDHC from Samsung. It runs like hell! :victory:
I've got sandisk 16 gb SDHC class 4
and it runs like hell, so i cant imagine what class 10 is doing ....
but if you dont care spending another 10-20 bucks, then go for the class 10!
I have a 16GB Sandisk Micro SD Card. Its been working just great!
I paid 12USD.
Is it a big difference between @4 and @10? Worthy to pay more?

It's Big difference. 4MB/s vs 10MB/s write speed is big diff.
