The probability of a soft error during RAID-5 rebuild (which takes a long time for large HDDs) after a disk failure is statically significant for larger HDDs. Most RAID system will abort the RAID rebuild if an (soft) error occur (and then you have to recover from your backups ? you do have backups, right? :) I?ve gone to RAID-1 for my own personal NAS at home (and I use ZFS to ensure data integrity for you geeks). I only get 50% utilization but at least I can be sure that at least one copy will be usable after an HDD failure. I?ve had at least 1 HDD fail and 2 HDD go flakey on me over the last year or 2. Always just past the end of the warranty period. My back up media is a single external HDD that is big enough to hold a copy of everything on my NAS. It?s a bit cumbersome but I don?t have the budget for a robotic tape library. :-( Regards, Spencer > On Nov 14, 2016, at 0:26, Jayanand Govindaraj <jayanand at gmail.com> > wrote: > > So do I. 4TB x4 in a Synology NAS in Raid 5 array.
