>It seems I had several bad cards
Let me repeat this, it's not worth buying crappy cards
the best test
sudo iozone -e -I -a -s 100M -r 4k -r 16k -r 512k -r 1024k -r 16384k -i 0 -i 1 -i 2
This may give bogus high speed results, what you really care about
is the 4&16k rewrite speeds, most right column
Is it bad or terrible? It will never be good
10-12x is my cutoff (floppy speed=150k/s)

Never came across iozone before, so much obliged!
