From 1999 until about 2003 I had a system that was maxed out with 4 IDE hard drives, so I installed 4 more drives in a second computer case and powered them from the power supply in that PC case, but connected their data cables to an IDE controller card installed in my main PC, giving me a total of 8 (smallish) drives. Before that, I did essentially the same thing with some SCSI drives, (the controller was internal but the drives were external), so the concept of "external drives that think they're internal" has been around for a long time, including a long time before I stumbled upon it.

The purpose of these drives is not for full-time storage needs, they are only for backup and archival requirements. Think of them as fulfilling the same purpose as tape drives. So connecting them to an internal SATA/RAID controller is totally out of the question, the drives in question may be powered down and put away in a closet after backups. Yousuf Khan

Considering the price of the rackmount unit you linked to ($1652), I'm not doing too badly with what I put together at 3TB, and a cost of less than $250. I might also have trouble putting that rackmount into a closet or cupboard later. :) Yousuf Khan |
