There are various disk benchmarking tools (bonnie++ is the one that comes to mind, I think also postmark or postbench), but for this use case, just do this:

for boo in  `seq 1 10`
do
time dd if=/dev/zero of=/some/file bs=1M count=100
done

Do a little math, average the values, and this will give you a pretty reasonable estimate of raw write speed to the filesystem.
