Andre, how are you benchmarking drives ?

In context you wrote, I've got rather curious results (maybe due to
daulty measurement routines in tar).
I've made
tar clvf /dev/null --totals
and got as follows:

for ReiserFS: 53MB/s
for ext2fs 27-28 MB/s

Hardware used:
ASUS P2B, 80MB RAM, P III 500MHz, ASUS PCI Ultra66C card
(based on CMD 648U) and 15GB WD153BA 7200rpm drive.

Have you any idea did such results are really possible ?
Could you sugest me better methods ?

Another question: looking through ide driver code I've found
that there exists bad drive list with comment saying that
it's updated when somebody emails bad words about drive.
What you think about preparing test utility and let people
around the world check and fill database of drives real "capabilities".
This way list will be almost completed now, not after few years.
