Pegasus J4: One Part of the Switchover Solution for the new Mac Pro?

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

I don’t really want four separate cases; and neither eSATA nor USB3 are options (four cables and not enough ports for one thing). So these SSDs must be re-housed in a 4-drive case.

Enter the Promise Pegasus J4 Thunderbolt case which houses four 2.5-inch SSDs or hard drives. It became available for sale today at about $390. It has fans, so I have to reserve judgment on noise level, but it looks like a high quality solution, albeit at a premium price (though at the current juncture, mighty welcome).

It works as JBOD or RAID-0 striping or RAID-1 mirroring (software based).

I hope to review a unit in a few weeks. I confirmed with Promise chat support that RAID is done via software (Apple’s Disk Utility), which rules out RAID-5 (one parity drive), but striping or mirroring can be done.

Promise says that if the unit is purchased with drives that it comes preconfigured with RAID-0 striping. Remember that if RAID-0 striping is used, failure of one drive kills the RAID entirely. Keep backups (clone) or use a RAID-1 mirror of a pair of these units.
