Several readers have emailed to ask whether RAID-5 or RAID-4 can be partitioned into multiple volumes. Indeed it can:

Note that OWC offers a RAID-5 edition of the Thunderbay, which comes with SoftRAID 5 included. The MPG recommendation for most users is to NOT use one large 12/15/18TB volume, but to “chunk” it (partition it) into 4/5/6TB volumes that thus match the 4/5/6TB capacity of single-drive external backup volumes. This has the operational advantage of simplicity when cloning.
