Hi AJ ONeal,
Very interesting benchmark about microSDHC speed. I have tested in my Overo with a Kingston 8 GB class 4, booting from NAND (Kernel 2.6.33) :
root@overo:~# dd if=/dev/urandom of=/media/mmcblk0p1/rand.dd bs=1M count=100
100+0 records in
100+0 records out
104857600 bytes (105 MB) copied, 189.881 s, 552 kB/s
552 kB/s writing over it  seems to be a little bit slow, right? (I'm not sure if I have run 'dd' correctly)

Subject: [Gumstix-users] microSDHC write speed comparison

I'm testing out various brands and classes of microSDHC to see which actually perform as they should and whether the microSDHC or the gumstix data bus is my write speed bottleneck.


So far I would recommend Kingston. It's more expensive, but it performs well. I should have a class 10 of theirs soon to test against.
