[QUOTE="pigoo3, post: 1808796, member: 56379"] [U]Two things to be careful of before purchasing drives: [/U] - drive size (footprint) - drive speed (rpm's) There are 3.5" "desktop" hard drives and 2.5" "laptop" hard drives. The 2.5" are obviously smaller & lighter (great for mobility/portability)...but sometimes cost more. Since the drives I purchased were for backups only (no portability needed)...I purchased two 3.5" drives. I feel 3.5" drives are more durable than 2.5" drives...but haven't really looked at any recent data. Also pay attention to hard drive speed (rpm's). When I was shopping I needed two separate HD's for redundant backups. I was choosing between two 2TB drives...or two 4TB drives. Drive cost was linear (basically same cost/TB of storage). I decided to go with the two 2TB drives...since drive speed was 7200rpm...compared to the 5900rpm of the 4TB drives. HTH, - Nick [/QUOTE]
