Is there any simple command (or tool) to test the speed (MB/sec) of disk access?

I've found hdparm but It look it only works for local disk. I need to evaluate the speed of remote NFS-mounted disk.

Thanks in advance!

Try IOzone. Or just time how long it takes to dd from your filesystem to /dev/null, or from /dev/zero to your filesystem.

It looks the hdparm uses dd in underlying too. Thanks! – ahmad Nov 13 '12 at 8:16
