I bought a Patriot 4GB class 10th micro SD card for my Hero. I was transfering music to my phone and I noticed it was only going a little above 2 MB/s. I thought that was a little slow so I ran CrystalMark benchmark and got the same result write speed.
To make sure it wasn't my phone, I put the class 10 card in my girlfriends completely stock hero and got the
same exact results. The stock card gets more than double write speed.
Now, taking these cards out of the hero and using a adapter and inserting it into my laptop, results are much better. The class 10 card is outperforming the stock card by nearly double.
Anyone know what's going on?

This would be my guess. I'm assuming your stock was a class 6?

I'm not sure what my stock SD card is but people claim the stock card is class 2, though mines performs like a class 6.
if the Hero only supports up to class 6, does that mean a class 10 will perform slower than a 6.
I rooted and installed nfinite's .7 ROM on my girlfriends hero. Our phones are now identical except for the SD card. While transferring music back to her phone, I noticed it was going even slower than mines, around 1.85 MB/s. Looks like it's the ROM causing the speed issue, hmm.

The stock 2gb card that came in my hero was a class 2, and my hero was purchased a week before the evo came out. I put a class 4 8gb card in the phone and it runs fine... I was going to purchase a class 10, but I'm glad I didn't now.

Just to be clear, it was the ROM which was causing slow SD card performance. I'm now using aospMod and I'm getting nearly 6 MB/s write speed.

Right now i have a 4gb Class 6 SD card and am looking at getting a 8gb Class 6 card for my G1 any ideas on a good brand to go with. I was thinking of getting a adata one but wasn't sure if there is something better to use. I plan on using this card mainly with Hero.

I've been using a Transcend 8GB class 6 for a couple of months, and it has never failed me. The cards has never shown up as "damaged" and app2sd is always reliable. The card can be found on amazon here
Just wanted to drop in and tell everyone about the sd card I bought.
http://cgi.ebay.com/ws/eBayISAPI.dl...zFgKt7nRXQb%2Bai8%3D&viewitem=#ht_1136wt_1139
Speed is awesome. I can restore an image from recovery almost 5x faster than the stock card. My hero seems twice as fast just doing day to day stuff. I can't believe I didn't do this sooner. I had no idea that the system depends so much on the sd card.
FYI, stock card is class 2 (read 2MB/s). This is class 10 (10MB/s). 8GB is platy for me and you can't beat $17.99 free shipping. I'm getting one more for my wife's intercept.
BTW, incase the listing is gone in the future this was:
Patriot LX (Class 10) 8GB MicroSDHC Flash Memory Card

Nice find, I paid $23 for a 8 gig class 6 just last week. You are right about the speed improvement, I was running a 4 gig class 4 before and I can tell the difference!

This card is amazing! I finally found out why it took so long for the phone to start ringing when the call was coming through. Guess what... I had the ringtone downloaded on the damn stock slow-ass class 2 sd card which took forever to load the sound LOL.
I wonder how many people are having lag issues with their hero not realizing this sd card limit problem.
Hmm I'm debating getting a Class 10 16GB but I might just disable A2SD since I'm pretty sure that the internal memory is faster than a class 2 microSD card.

Yeah, for sure it is. But I don't run apps2sd even on this new class 10 card simply because cm6 has plenty of room for me and it's froyo 2.2 so I can move each app to sd individually. However, ringtones are downloaded to sd (wherever you get them from) and when selected as a ringtone in the main system they are not moved to memory anywhere. They still are executed from the sd card.
Just bought this card from newegg. It was a bit more money but I couldn't find it listed on eBay.

The higher the class, the higher the speed.
The Hero only recognizes up to class 6. If you buy a class 10 sd, it will work, but you'll have the same speeds as a class6.

When I'm hooked up to the PC and writing to the card it barely gets over 4 mega bytes/s but when I read from it it caps out at exactly 10 mega bytes/s.
I'm not sure where you are getting your info from but all I'm saying this is what's happening as far as I can tell.
Hmmm... I just thought about that. Between the PC and the hero it should read whatever the class is but not necessarily between the SD and hero itself. I'll have to download the app to test sd speed and see.
Tried 'sd card speed tester' from the market?

Cool I just got a 8GB class 6 with Deca's stable #6 kernel and its so fast
Well... it just died on me!!! Along with all my data on it.
The thing will not respond at all. I might as well be putting my fingernail in the slot. I tried other cards, they mount just fine. I also tried my laptop and still no go.
Patriot memory sucks
Now that I was forced to switch back to the old card I'm getting awesome battery on my phone. I think that card may have been going bad for a while and maybe the phone never went to sleep because it kept trying to mount it. I know the few days before if died it kept dismounting it and I had to rensert it to mount.
Just an observation that battery life could be also related to your card.

Saw this card on Newegg today. Pretty cheap for a Class 10 16GB card and reviewers state it meets Class 10 standards, and that it appears to be a rebranded Samsung card, so it is a quality product.
Android only supports Class 6, meaning this card should be plenty quick, and will utilize full Class 10 potential during file transfers over USB.

Wintec 16gb CL10
Just got the Wintec 16gb CL10 from Newegg, put it in my Sprint Hero to format and as soon as it finish saying setting SD card the screen locked up. removed battery/ installed and saw installed apps icons were gone in its places gear icon. Installed original 8gb and app icons were back but apps came up with FC. removed each app and reinstalled and they work fine now. I'm afraid to put the 16gb back in, it seems fine in my laptop. I have no idea whats wrong!
I got one of these around Christmas. Formatted, partitioned and transferred my stuff. I thought all was well until I had to restore a nandroid and it bootlooped. I put my old 8G Sandisk back in and haven't tried again. So my experience was it worked about a week. I guess it's a write/read issue. I had trouble with recovery mounting the card to even see my backups. I had read reviews of spotty quality and I guess I had the bad luck of the draw.
hmmm ok then I guess i'll pass on this one. I want to get one that'll last so i can transfer it to a new phone when i upgrade.
on htc website, it says microSD 2.0 compatable, & i know some phones can only support so much extra storage, ie: some say microSD up to 16gb, so maybe the hero doesnt support high capasity cards.
anybody got a conformation on how big a microsd card we can go, that wont cause issues.
i was looking @ this card in the OP, but now im double thinking.

I bought the wintech 16 gig card back in january and 15 days later I woke up and my phone said the sd card was not formatted. Both windows 7 and ubuntu 10.10 only saw the card as 1 gig but neither could format it nor create new partition tables. I lost all the data but luckily had a semi recent backup on my computer. RMA'ed it back to newegg and got a 16 gig class 6 card from a more reliable manufacturer.

I very recently got a NC, and I've tried running both Froyo and Gingerbread from the microSDHC card. I'm using a Class 4 card, and I noticed that both seemed to lag quite a bit. Do you guys think I'd see a difference if I used a Class 6 or Class 10 card? Thanks!
--Adam
I think the most important question, is what brand are you using? The class ratings might mean something if they were enforced, but the sad fact is that they are not, which leads to lots of cheap, crappy cards out there.
I have a Kingston class 4 that barely makes class 2 speeds, and an 8GB Sandisk class 2 that falls between class 6 and 10 (in real world speed). If you get a GOOD card, running Froyo/GB from it will be smooth as butter (Running the posted custom Froyo on my Sandisk, and it is as fast as the stock ROM on the eMMC).
I believe the class number corresponds to the cards base transfer rate. For example class 4 is 4 mb/s, where class 10 is 10mb/s. Depending on the brand and how much you spend, class 10s can go even faster than 10mb/s. This is a significant difference, but I don't know how much it will actually affect the real performance of NF and HC on SD.
I just ordered a class 10 to see this for myself because I originally tried it on a class 4 card as well, and wasn't happy with it. I will post again when I try it.

Is there a utility that people are using to TEST the speed of their micorSD cards, or are you just monitoring the transfer rate when moving files?

There are plenty of free drive benchmarks out there, but my real world tests are good enough for me. When i use either dd (linux) or the windows image burner for creating/backing up my Froyo images, i get a very solid indication of my transfers.

In market there is a benchmark for sd thats free (can't think of the name) but I believe the nook only manages 3-6mbs r/w no matter the SD.

Among the many cards I've tried I had the 16GB version of that (class 4) card. The Sandisk 16GB (class 4) I got bested the Patriot and oddly some others that were supposed to be Class 10. It was the only way I got Froyo and especially HoneyComb to run reasonably.
I just downloaded the app System Benchmark on my Evo and tested the Class 4 Sandisk in there:
Write: 7.1 MB/s
Read: 10.6 MB/s
Not too shabby at all, I think when I get home this baby is going in the NC.

It should run it amazingly. My SD gets 7.4 write, and 12.x read, and Froyo on it runs as smooth as elcair does. It has really become my daily driver.
On my Kingston class 6 I get 9mb/s write, on my Sandisk class 4 I get 3mb/s
I just installed System Benchmark from AnTutu also to have a dollars to dollars comparison and on my KingMax 4GB Class-10 in the NC running HC I get 9.9MB/s write and 18.5MB/s read... running the complete test takes forever though it seems...

Well, at least that's the expected outcome considering the Kingston class is higher. The sandisk class 4 card I have gives me ~ 5-6 Mb. If it's true that the NC can't benefit from more than 6 Mb then I won't ever need anything better.
I found with both my Kingston 4GB class 4 microSD and Kingmax 8GB class 10 microSD that the nook runs laggy. When I run Froyo off of the internal memory, it runs fabulously.
For reference, I got about 6MB/s on my Kingston Class 4 and 11MB/s on my Kingmax class 10. This was on my PC of course, I didn't test the speeds from then nook, but only noticed it lag and crash more often (compared with internal memory).
I just put one of the CM nightly builds (build38) on a uSD card (sandisk 16gb class 2) and there is a major lag to even enjoy the device. I have been reading about that sometimes class numbers on the cards don't mean too much.
Which card would you recommend to run CM from (Brand/class/where to buy) from your experience?
any class 6 card should be plenty enough (as long as it has enough room for the ROM and stuff) even class 4 should work much better (but still some lag i beleive, idk ive never tried it)
newegg is a pretty good place to shop for them. Heres one such card - newegg.com/Product/Product.aspx?Item=N82E16820211341&cm_re=8gb_micro_sd_card-_-20-211-341-_-Product
There is a long thread about this on here and the class 6 Transcend 8GB card got the most mentions for good perfomance. The probability for issues to arise increases when using cards over 8GB.
I have a class 2 Sandisk 8GB and class 6 Transcend 8GB card. They both work well.

I used that card for HC v4 and it was fine.
I've got 4 uSD card: one Dane-Elec 2G no class, one Kingston 2G no-class, one Transend 4GB class 6 and one PNY 8GB class 4. All run CM7 very well, maybe I didn't pay attention but didn't notice much different in performance. In benchmark, the write speed is about 5-7 MB/s.
The higher capactity 16GB card seems to have more problems, other than that every card will do.
You should check into the random read/write performance of small files on these cards. sometimes the class 6 or 10 aren't all they are cracked up to be. Fast transfers of large file yes, but general performance can suck.
sandisk class 2 or 4 cards can have excellent perf. I have a class 10 that is outperformed by class 2/4 and 6 cards.
if you are having problems with crashing, etc. try a basic sandisk and see if perf. is better.
there is a thread about it but i can never find it.
