Related story .... Why RAID 5 stops working in 2009 | ZDNet http://www.zdnet.com/blog/storage/why-raid-5-stops-working-in-2009/162 Due to the size of modern drives, one can apparently EXPECT a read-failure during a RAID-5 rebuild, so RAID 5 is no longer reliable enough. With 120GB drives it was fine. With terabyte drives it isn't. RAID5 versus RAID10 (or even RAID3 or RAID4) "To put things into perspective: If a drive costs $1000US (and most are far less expensive than that) then switching from a 4 pair RAID10 array to a 5 drive RAID5 array will save 3 drives or $3000US. What is the cost of overtime, wear and tear on the technicians, DBAs, managers, and customers of even a recovery scare? What is the cost of reduced performance and possibly reduced customer satisfaction? Finally what is the cost of lost business if data is unrecoverable? I maintain that the drives are FAR cheaper! Hence my mantra: NO RAID5! NO RAID5! NO RAID5! NO RAID5! NO RAID5! NO RAID5! NO RAID5!" http://miracleas.com/BAARF/RAID5_versus_RAID10.txt -- Angus Scott-Fleming GeoApps, Tucson, Arizona 1-520-290-5038 Security Blog: http://geoapps.com/ ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin
