The MobileRAID MR4UT series is the latest addition that utilizes 400MB/s I/O processor and 128 ECC memory hardware RAID engine, providing over 210MB/s read and 170 MB/s write RAID 5 performance via eSATA interface. The built-in RAID engine also allows the MR4UT to operate on alternative USB or eSATA connections without OS compatibility issues or the need to install drivers.

The MR4UT is a cost-effective solution that utilizes enterprise-level features derived from Sans Digital 16-bay rackmounts. Advance features such as online capacity expansion and RAID migration allows flexible capacity expansion, while minimizing data access downtime during the process. RAID configurations can be configured via the built-in LCD panel or via the embedded IP-based web interface, allowing convenient administration of the MR4UT remotely or locally. In additional to high performance, the MR4UT overcomes the 2TB per volume limitation, fully utilizing the capacity benefit of latest 3TB hard drives. For OS with 2TB limitation, the MR4UT is capable of achieving multi-volume RAID, dividing the hard drives into four sets of RAID volumes, bypassing the capacity limitation.

4 out of 5 eggsGood external RAID

Pros: REAL RAID.. not raid via controller card on your pc.. Works well on esata w/o need of port multiplier. Supports large volumes (over 2TB).. (under windows convert/create partition to GDT to support). Can create 1 RAID5 or 1 RAID 10 then create several volumes (each showing up as a separate lun/physicaldisk.. to support it requires port multiplier or under usb only).
On esata 1.5GB.. performance using crystaldisk is:
RAID5 (using 4x WD 640GB)
SEQ R/W (110/100)
Rand R/W (100/70)
4k Rand R/W (8M/8M (normal single hdd usually .8/4))

Cons: No way to change fan or add memory w/o voiding warranty.

3 out of 5 eggs

Pros: looks good, compact, multiple interface formats, easy set-up, probably the best unit on the market right now.

Cons: high price, power supply is somewhat noisy (high-pitched electronic whine + fan).
