Linux testing disk speed with dd

Best way is to use dd and try the following:

dd bs=1M count=256 if=/dev/zero of=test conv=fdatasync

“fdatasync” tells dd to write physically to disk before providing the output. Increase to 1024, 2048 if you want 1G or 2G file size. Bigger sizing will produce a more normalized speed.
