Promise debuts first internal hard drive sleds for new Mac Pro

Promise Pegasus R4i for new Mac Pro

The Pegasus R4i is a RAID module for the MPX Expansion slot, used within the Mac Pro. It contains four swappable modules that contain four 7200 RPM hard drives from Promise, pre-formatted. The unit is powered by the MPX bay power header.

The Pegasus J2i is a more conventional drive sled. Promise calls it a "direct-attach internal storage enclosure" and will ship with one SATA hard dive pre-formatted, with the ability to add a second drive. It appears at present that the J2i will connect with SATA cables to the internal header in the new Mac Pro, with what Promise calls a "custom internal cable assembly."

Both the drives and the sleds are covered by Promise's three-year warranty.

AppleInsider has requested pricing, with none presently available. The company says that both the modules will be available later in 2019 at the Apple Store, resellers, and Promise's distributors.
