[QUOTE="cwa107, post: 1163152, member: 24098"] I have 2 500GB Black Edition drives. In hindsight, I probably should have gone with the Blue series. In theory, the Green series drives should be fine, but I've heard they have some issues. NewEgg ratings are extremely low across the board. So, I think I'd recommend going with the Blue series, which are a good balance of performance and thermal efficiency. Yes, RAID 1 provides mirroring. So, if one drive fails, you don't lose your data. And you can rebuild the set by replacing the drive. Well, RAID1 provides redundancy, but that doesn't mean your data is backed up. It just means that a mechanical failure of one drive doesn't take all of the data. But if you were to delete something from the NAS, it's not like you're going to get it back. So, it might not be a bad idea to back it up occasionally. In fact, I have a single 500GB external that I run quarterly backups of the NAS to. You could theoretically do that, but it won't be fast. Rebuilding RAID sets on this device can take quite awhile, during which your data is unprotected. [/QUOTE]
