Hi I think if you use raid1 with at least 1 hotspare, you're pretty secure with a high datatransfer.. If one disk fails then the hotspare takes it place and gives the time to replace the broken disk..
Recently I put an old server from raid5 to raid1, because of the progresql. they recommended the raid 1 or raid 10 for performance. Although I never had serious problems with raid 5 ( always used combination of at least 3 disks and minimal of 1 hotspare.). No hardware problems, nor performance issues. But I mostly work with quite small workgroups (max 50 workstations). regards, Arno Op donderdag 11-03-2010 om 12:09 uur [tijdzone -0600], schreef Preston Hagar: > On Thu, Mar 11, 2010 at 11:26 AM, J.
