Promise Pegasus J4 — Overview

Last updated 2013-07-03 - Send Feedback
Related: SSD, storage, Thunderbolt

Update: see issues.

One piece of the puzzle for me to solve with the new 2013 Mac Pro is how to use my four existing OWC 480GB Mercury Elite Pro 6G SSDs (these are 2.5-inch SATA SSDs).

Enter the Promise Pegasus J4 Thunderbolt case which houses four 2.5-inch SSDs or hard drives, about $390. It works as JBOD or RAID-0 striping or RAID-1 mirroring (software based).

OWC sent on loan a Promise Pegasus J4 (Thunderbolt) along with four OWC Mercury Extreme Pro 6G SSDs and four hard drives as well.

The 4-bay Promise Pegasus J4 is available as 0GB solution (you supply the drives) or a 2TB (4 X 500GB) solution at OWC. Drives apparently need to be 9.5mm or less thick (not 12.5mm).
