The SS4000-E supports up to four hot-swappable SATA drives. Since the largest drives available are now up to 750 GB, the total maximum capacity of the SS4000-E is a whopping 3 TB. We loaded our test device up with four Western Digital Caviar WD2500YD, 250 GB, RAID Edition drives, for a full terabyte of networked storage.

The SS4000-E can be configured to use its four drives in RAID 0, 1, 1+0 and 5 configurations. There is also an "Alternative RAID 5 + Hot Spare" option available where the "spare" drive is ready to take over instantly for any of the other three drives in the array, should one of them fail.
