Thank you, everyone!

Post #296,485 by slugbug 11/27/07 1:23:32 PM Reply	Thank you, everyone! Really appreciate the input. One other question: what level of RAID protection is best if my goal is to split the drive space for backup purposes? RAID 0,1,5? Still researching.... My thanks, Slugbug

[link\|http://www.acnc.com/04_01_00.html\|RAID 0] is striping. No redundancy, but higher performance than a single drive. [link\|http://www.acnc.com/04_01_01.html\|RAID 1] is mirroring and duplexing. 100% redundancy, but 50% of disks are effectively lost. [link\|http://www.acnc.com/04_01_05.html\|RAID 5] is a good compromise of performance and reliability. It has the most complex controller, and requires at least 3 drives to implement. If you're doing on-line live backups, RAID 1 is a simple choice. You don't have to think about it. There's a lot more at ACNC. HTH a bit. Good luck! Cheers, Scott.

Post #296,495 by slugbug 11/27/07 7:16:35 PM Reply	Probably 1TB x 2 (RAID1), if possible... otherwise, can survive with 500GB x 2 (RAID 1) and do multiple configs. My $0.02. -Slugbug

Post #296,505 by crazy 11/27/07 10:28:05 PM Reply	Assuming 3 disks Yup, you lose 1 disk out of however many disks you have in the raid set. As you add disks, you gain speed because you have more spindles, and both streaming reads / writes get faster. But rewrites get dramatically slower as you add disks. So it really depends on your usage pattern of whether more disks are better or worse for you. Of course, there are many other variables to think about if you were really pushing for performance.
