Re: Recomended FS

I'm not a HD specialist but I know scsi can handle load much better the IDE.

I read a benchmark lately ( don't really remember where ) checking SATA
against U160, the result show that SATA give better performance at start.

but later on the SCSI take it while HD cpu load is 30% and the SATA is 100%
load for the same task.

So I see its kinda obvious for me, if its a server serve lots of files and
the HD will work against lots of users ill go for the SCSI.
For a workstation or backup server ill go for IDE.

But still the greatest question is what FS to put on ?

I heard Reiesref can handle small files very quickly.
