The A-Data 4GB Class 6 SDHC sucks.

Get Transcend or Kingston.

 

Check out this page, it is for cameras... but for our purposes, look at the read speeds: SDHC Benchmarks

Some I found interesting were: Read Speed (Kb/s) (64k data)

Transcend MicroSD Class6, 2GB (FAT16) 6045
Transcend MicroSDHC Class6, 4GB (FAT32) 7764
Toshiba MicroSD SD-C02G MIJ (fat16), 2GB 6062
SanDisk MicroSD, 1GB (FAT16) 7621
Kingston microSD, 512Mb 5093

Edit: ROFL.. i almost wanna try one of these cards for my EDGE... just for the brand name

 

Too many issues on A-DATAs

I heard that it slowed down the enhanced menu, and that there were a lot of faulty units.

I decided on the Transcend. No problems as of yet.

I've had the card for half a year.

 

I bought a 4gb class 4 Toshiba and am pretty happy with it.

 

The A-Data Cards are one of the fastet cards on the market.

 

I'd stick to kingston no matter what they say.

 

I'll tell ya. I have a Transcend Class4 8gig in my Cyclo. My bro has a A-Data Class6 8gig in his cell phone. My Transcend seemed to transfer files MUCH faster to the card than his A-Data did when hooked up via the Cyclo's little USB microSD reader. Read speed seemed comparable, but write speed was drastically different and MUCH better on the Transcend.

Castlevania PoR still tends to lock up on my Transcend though. I tried his A-Data in my Cyclo with PoR and it didn't appear to lock, but I only spammed the transport thingy's for a couple minutes as a test, so I can't say it was actually any better. I can sometimes do that on my Transcend too.....

I CAN say that the A-Data card seemed to take slightly longer to load up the menus in the Cyclo though.

I don't really have any data on transfer speeds for the 2 cards. I did do some tests on the Transcend when I first got it, but I don't really remember the results anymore. But by direct comparison in usage tests, the Transcend Class4 seemed actually faster than the A-Data Class6.

 

Who cares about write times? Like PharaohsVizier said it's all about the Random Access Times lol
I use the A-Data 4GB class 6 and have had no problems in my cyclo ever.
