    Worked fine for a while then keeps killing the internal drives and now just keeps shutting down at random. Big expensive brick!! Save your money and buy a LaCie or Drobbo.

    Horrible reliability and customer service.

    • Written by Tania H from Lake Balboa

    Individual drives continually fail, even though each "failed" drive works perfectly fine in any other enclosure. My last firmware update from Promise corrupted my file directory leaving my Pegasus visible in Disc Utility but unable to see or access in the Finder, leaving 3tb of data backed up with a raid 5 useless. Promise was useless with assistance, even telling me my Promise Raid was not compatible with 10.10.5. I was able to fix the problem spending $120.00 purchasing DiskWarrior 5 that instantly repaired my file directory. I cringe waiting for the next firmware "update". I would steer clear of these overpriced trouble making bricks.

    It died.

    • Written by Janet M P from Bellevue

    I purchased this with my mac pro desk top thinking that I would store all of my photography on this and just let my mac do the heavy lifting with the lightroom catalog and photoshop ad nauseam. But that software does me no good without the images which have disappeared conveniently, or not so much in my case, during my efforts to consolidate and make copies of several years worth of my images. This has not been a happy day. So beware, perhaps there are more dependable options out there. I am searching for them.

    Not Reliable.

    • Written by Tania H from Van Nuys

    The Chassis fails like clockwork, always the 4th drive bay. I've just replaced my 4th bay drive again for the 6th time since purchase and Pegasus would not exchange the unit while under warranty. I would not pawn this problem onto someone else by selling it when working, Just want to share my problem and let others know buyer beware.

    Works great, but no longer diskless

    • Written by David P from BEAVERCREEK

    This is a great enclosure so far (I have 2 enclosures with 4 arrays) but I was able to buy them diskless. My only complaint would be the thunderbolt cables included were way too short. Also, now they are no longer available in the Apple Store in the diskless form and the others are a total rip-off due to hyper-inflated drive prices. BRING THESE ENCLOSURES BACK DISKLESS, APPLE!!

    Excellent storage, but at a premium price

    • Written by Jukka L from SAVONLINNA

    My Pegasus 8 TB drive is close to a perfect storage solution: very fast, reliable and safe. One of the very few problems (besides the high price) is the annoying running noise that it makes, so I have placed it on a low shelf, out of sight, with a long cable. The other big problem is that the unit loses data connection with the Mac, whenever a cell phone is placed in close vicinity. Of course, this also makes OS X go berserk, accusing me of ejecting the drive in the wrong way (which I didn´t). Now I have learned, the hard way, to keep my iPhone at a distance of at least one metre from the Pegasus at all times. With this in mind, everything is honky-dory!

    Great match with the new Mac Pro

    • Written by James H from Merritt Island

    It did a lot of research and soul searching before diving in with this device. It's a great match with a new Mac Pro. The Thunderbolt 2 interface between the two devices is seamless. The Pegasus is configured at the factory for RAID 5, which is what I intended, so I really didn't have to do any configuration on it, except change the default device name for my own purposes. It took about 4 hours to do the initial RAID 5 sync and the system is still available for use during that time. I delayed heavy data transfer from old devices until the sync finished because using the system slows down the syncing process. After plugging in, the Pegasus does need to be attached to the Mac via the Thunderbolt 2 cable (included with the Pegasus). The Pegasus doesn't really come alive until it's attached to the Mac. The configuration utility (downloadable) has gobs of configurables and readouts. Once running, it's very fast. I'm using it for video rendering and this device certainly is not a bottleneck. I'm a happy camper so far!

    Very good, but not perfect

    • Written by Shaun P from FELTHAM

    The build quality is excellent, as it should be at this price for desktop storage.

    Performance is very good - over 500MB/s stained on sequential workloads, and reasonable performance on random I/O too. To be fair the random I/O is never going to be a match for SSD with SATA HDD's, but if you want to the drives can be replaced with SSD's.

    My only real gripe with this unit is the noise. It's not terrible in a way that Drobo's are sometimes, but it's definitely noticeable. On my desk I also have a Synology NAS located approximately the same distance away on the other side of the desk. I can't barely hear this, even in a very quiet room (late on a night with the clock ticking in the background). I guess I'll just have to buy a longer cable and move the Pegasus further away from me.
