The Pegasus' on-board RAID controller doesn't care about the order in which you install drives for a single array (e.g. Blue indicates proper operation while red indicates a problem. There's surprisingly little resistance to inserting the drives completely, the entire motion is just very fluid.Įach carrier has two LEDs - status and activity. Pull on the handle and the drives slide out perfectly. There's a large square eject button on the front of each drive carrier - depress it and the handle pops out. The screws Promise provides with the Pegasus are too large for SSDs so you'll have to supply your own if you want to replace the HDDs with SSDs down the road.Įjecting and inserting the Pegasus' drives is incredibly smooth. The R6 has six removable 3.5" drive bays that accept 2.5" drives as well. Powering down the Pegasus requires that you hold the power button for ~10 seconds until the button glows red then release in order to avoid any accidental shutdowns. The power button burns blue when everything is functional, orange during startup and red if there's a problem with the array. Occupy a single port and one indicator lights up, occupy both and you get two:

There are two Thunderbolt ports on the Pegasus, one connects to your Mac while the other connects to any other DisplayPort/Thunderbolt devices in the chain. The glossy black strip on the left of the unit is home to the power button and the two Thunderbolt indicators. The front of the chassis is pretty clean. The metal construction combined with the six 3.5" drives gives the Pegasus R6 its 20.4 lbs weight (the R4 weighs in at around 15 lbs).
The color is a bit lighter with a more coarse grain.

The Pegasus chassis is made out of aluminum, similar to the unibody MacBook Pro and iMac but not quite identical. The PM8011 has an embedded 600MHz MIPS processor and is paired with 512MB of DDR2-533. On the R6 obviously only six of those ports are functional. This is an 8-lane PCIe Gen 2 controller with eight SAS/SATA 6Gbps ports. Internally Promise uses a PMC Sierra PM8011 8-port SAS-2 RAID controller. I did run into some reliability issues with the Pegasus R6 configured with 4 x SF-2281 SSDs, however it's unclear whether they were caused by the drives themselves, the Pegasus or a combination of the two. I did try installing Seagate 3TB drives and SandForce SF-2281 SSDs in the system, both of which worked. These are four platter drives with 64MB buffers. The 12TB Pegasus R6 we received for review came with 6 x 2TB Hitachi Deskstar 7K3000 drives. Through Apple you can buy any of four configurations: Promise Pegasus LineupĪll of the configs ship with 3.5" 7200RPM hard drives and are configured as a single RAID-5 array by default, although Pegasus supports most of the common RAID formats (RAID 0/1/5/50/6/10). The names are easy enough to understand, they simply refer to the number of drive bays. Promise offers two versions of the Pegasus: the R4 and R6.
