Despite its small size and unassuming design, the two-bay Iomega StorCenter ix2 packs in business features as well as performance. You can buy models with a range of capacities (from diskless to 6TB); we looked at the two-disk 2TB version with RAID 1 mirroring, connected to a gigabit Ethernet network. If you're fitting drives yourself the front panel snaps on and off easily and you don't need tools to pop a disk out or snap the drive rails onto a SATA II disk. You can also plug in an external USB drive as extra storage €“ or use the USB port to connect to a UPS that will shut down the StorCenter cleanly if you have a power failure.
