4TB Drives Not Supported
I added 4x4TB Hitachi drives. Worked well in two Raid-1 arrays. Then I migrated all 4 to RAID-5. Promise Utility converted all 4 t I added 4x4TB Hitachi drives. Worked well in two Raid-1 arrays. Then I migrated all 4 to RAID-5. Promise Utility converted all 4 to a RAID-5 and correctly found 12TB/16TB to be usable.
HOWEVER, OSX Mtn Lion does not recognize this size of RAID and gives back a 4TB limit. Frankly, this looks like an OSX glitch more than a hardware problem--but it is a major impediment to maxing out storage.
Contact with Promise Customer support was desultory and unhappy. Web support just said 4TB drives are not supported. No offer of workaround, nor prospect of firmware revision. …

Looking forward for spectacular Unit!!
I picked mine up the 2Tb version and it takes full advantage of the new Thunderbolt technology. I am a film-maker using the latest I picked mine up the 2Tb version and it takes full advantage of the new Thunderbolt technology. I am a film-maker using the latest D-SLR technology to produce high definition videos, which can occupy a lot of hard disk space very quickly, and this device is perfect for me, especially when it is also available with 3Tb!!
I use this directly with Final Cut X and Final Cut 7 and it reads and writes files very quickly. Your attached storage is no longer a bottleneck. Just Perfect - Thank you Pegasus - Flying data with the fastest speed! …

Have the 12tb version which went through two separate drive bay failures before Pegasus software updates fixed overheating problem Have the 12tb version which went through two separate drive bay failures before Pegasus software updates fixed overheating problem. Drives replaced without charge as under three year warrantee . But after warrantee ...yikes, expensive. Tech support good and no problems since then. Working on at 2011 iMac with Mtn Lion. Crazy prices though for these boxes! Daisy chaining separate 4tb boxes seems only other option for normal folks sadly …

Works but the drives are flakey
I've had this running for 2 months now, no errors and a drive just died on me today. Not a big deal when you configure RAID 5 with I've had this running for 2 months now, no errors and a drive just died on me today. Not a big deal when you configure RAID 5 with a spare but still a pain and a little sad considering I have other RAIDS that have run 2+ years without a dead HD.
Just be warned that the Seagate drives they ship are consumer grade and aren't the most reliable. …

I have two running just fine 24/7.
We have two units both working just fine after being online now 24/7 for nearly 4 months. You must set these things up right howev We have two units both working just fine after being online now 24/7 for nearly 4 months. You must set these things up right however. I experimented with them a bit first. I was able to software RAID two units together into one 30 TB volume. That was cool, but it got me a bit worried about losing data. So I reset them up as two logical drives, each using 5 drives for the RAID and allowing one to remain as a hot spare. This yields two 12 TB volumes. I lost a bit of storage potential, but it's rock solid safe now. Easy to daisy chain these together too, but there is no thunderbolt cable included. That's pretty unbelievable actually. Other than that though, a nice product. …

Can I partition this into 3 volumes - storage, backup and time machine?
- Asked by Richard C
On the older 12TB model, once the Pegasus was up and running, I made an active Time Machine partitio On the older 12TB model, once the Pegasus was up and running, I made an active Time Machine partition, a partition for a Carbon Copy Cloner (CCC) backup of my iMac 12,2, and a file storage partition with a folder containing Virtual Machines (VM's) of other machines in Parallels using the OS X Disk Utility. Another partition could be made for a backup of the storage partition, although I use an older eSATA RAID storage device off of the second iMac Thunderbolt port (with adapter) for backup storage so it's on another physical device in case of a device hardware failure. I don't own the 18TB model, so I can only infer it would work. I can say my VM's of Linux, Windows, and Windows Servers running off the Pegasus R6 12TB RAID device on a gigabit Ethernet work well. Thunderbolt delivers where speed is concerned. Having a RAID Array and knowing that a hard drive failure won't shut down the system adds peace of mind when traveling. I have had remote (offsite) reboots of the operating system using the OS X built-in VNC screen sharing randomly freeze on either the light blue or gray start-up screen. Random in this case means 1-2 times out of every 10 reboots. I added an Ethernet camera for viewing and multi-outlet Ethernet web power switch so that if overseas I can view and reboot the iMac or Pegasus R6 (or any other device) remotely by cycling the power at the outlet level if needed. My R6 is quite quiet as well. Overall, I am satisfied with my PROMISE Pegasus R6 12TB Array, and would recommend it to a friend. …
