You can get them in cat5, usb 3.0 and thunderbolt. Lighting fast data transfer rates.
Witht e Drobo's you do not have to match all the drives unlike the older NAS systems.
You can load 1 TB, 500GB, 2TB, 1.5TB, 3TB its just great!

The old NAS systems are single drive redundancy, not as good nor the data transfer rates.
