The Promise Technology 8TB Pegasus2 R4 is a Thunderbolt 2 RAID storage array designed for simultaneous streaming, editing, and backup of high-resolution videos and large multimedia files. This storage array's Thunderbolt 2 interface offers high-speed connectivity. The Pegasus2 R4 stores up to 8TB of data and consists of four 2TB 7200 rpm SATA drives. Actual storage capacity will differ according to the RAID configuration. These drives are hot-swappable for easy access and come pre-configured in RAID 5 mode, which is optimized for data protection, capacity, and performance. RAID levels 0, 1, 5, 6, and 10 are also supported; each level offers configuration options for capacity, data protection, redundancy, and speed.

The Pegasus2 R4 storage array has dual Thunderbolt 2 ports, one port for direct system attachment and another port for daisy-chaining up to 6 Thunderbolt 2 devices. This storage is formatted in the HFS+ file system for Mac and is compatible with Time Machine in OS X, which automatically backs up your entire Mac system.

Thunderbolt 2
The Pegasus2's Thunderbolt 2 interface is sufficient for handling and accelerating 3D or 4K (UHD) workflows. Thunderbolt 2 uses the same cable as the previous generation but has double the available bandwidth for a maximum throughput of 20Gb/s.
4K Workflows
The bandwidth of Thunderbolt 2 and the Pegasus2 is designed to give professionals the ability to edit and view live 4K streams while backing up the same file to a single or daisy-chained Pegasus2 storage array system.

      I bought the Pegasus2 R4 to use as primary image and data storage for my new 2013 Mac Pro. As a semi-professional photographer who uses a Nikon D800, I need storage that is fast and vast.
      My Mac Pro has not been delivered yet so I have been testing the Pegasus on my 2012 15" Retina MacBook Pro. Blackmagic speed tests show the Pegasus2 R4 is as fast or faster than the internal SSD in my MacBook Pro. Wow!
      It's too early to say anything about reliability and durability but, so far everything looks great.

      bought two units, one unit worked as advertised, the other unit had problems with shutting down. emailed technical support at Promise. Their response would be great for a programmer or an IT professional but not for me. Time is money and I don't have time to fix Promise's problems. If it doesn't work out of the box send me one that does.

          Plug and Play set up as it's configured (RAID 5), albeit with a wait time for the raid to sync with my computer. The raid goes to sleep with my Mac. The fan isn't as noisy to me as others claim. I went a step further and tucked it into my desk drawer with an open back and I don't hear a thing, and my desktop is not cluttered. I'm really happy with the ease of set up and use, looks to be well built, and works well so far. The lightning bolt cable that comes with it is meant for desktop use, and you'll need a longer cable if you wish to store it elsewhere. Overall, I'm very happy with my purchase. Thanks BH for the great service!

            I've been using this for 3 months as the external drive for my MacPro and it has performed flawlessly connected using Thunderbolt 2. It is quiet, manages power well, and was completely seamless . It did not require formatting or fussing at all. Data speeds are also very good. I use it for storing all my data files as well as the referenced photos for Aperture. After 3 months the reliability is good. There is no downside.

            It does the job. It works as advertise. It's fast and a must for any New 2013 Mac Pro user. Using the software is ok. I'm new to setting up my own RAID so the software was tricky. I called Promise and their technical support is a joke. They are rude and are of no help. I had to beg them to help walk me through the steps. (I wanted the unit in a RAID 0. it ships as a RAID5)
            I have a corner desk so the unit is off to my left. I wouldn't call it quiet or loud. You can definitely hear the fan going.

              I purchased this unit in anticipation of my new Mac Pro. I have already transferred my data to it and first impressions suggest it is a superb performer. It is very quiet and very fast. The build is solid and look sleek. It is heavier than I imagined. It is to be seen how it performs over the longer haul.

                I use this for media storage for working video projects and as storage for other mission critical data. The speed is impressive with TB2 averaging over 700MB/sec write and 500MB/sec read. My internal SSD in the MacBook runs around 900MB/sec, so this RAID array is very close to the PCIe SSD. At RAID 5 redundancy is good, but I still backup anyway. Highly recommended.

                  I'm understanding Thunderbolt more now and I wanted a large raid 5 drive to store and back up my projects. The more Thunderbolt drives you add to the chain, the faster your computer goes and hence your workflow. I have a small Thunderbolt drive and I added this one to it. I can really see the difference. I think this is the only option available for editing video right now. Just plug it in and go (on an iMac). Actually, you have to wait about an hour or so for the drives to sync up or somthing, but then you're ready to go. I also just added a 12 TB Pegasus 2 to the chain and now I'm really whizzing along. I don't even hear it at all. Of course, I'm a little deaf in the high ends. Yes, I recommend it.

                    This is now attached to a 15" MB pro with retina screen whilst awaiting a new Mac Pro.

                    On first installing everything worked just fine in its default RAID 5 format. However on subsequent restarts the computer no longer recognised the drive - big problem. Not very much help from Promise!

                    I figured out the best was to reformat the array using Mac's Disk Utility (lost all the data that I had taken hours to transfer to the array). I then changed the array to a RAID 0 set up (which I wanted anyhow) and everything has been OK since.

                    On shut down and restart the drive behaves as it should. It is lightning fast but not as quiet as hoped - high pitched hum (probably fan noise)

                    I use this as my main storage for my images on a 2013 Mac Pro. The speed is nothing short of fantastic. It was a snap to set up. And it is just as quiet as the new Mac Pro -- really enjoying the silence. Definitely worth it.

                    Service from B&H was excellent as always.

                    (This replaced a Drobo that would not wake up properly when it went to sleep. It is now back on the iMac and works fine on that platform.)

                      We own a digital media company and produce video projects that require us to work with huge files, full HD footage (and up). We needed a super fast, reliable, RAID storage solution - something that would allow us to work with our files through an external drive, but offered thunderbolt speeds for a seamless editing/post production experience. We found it! The Pegasus2 R4 is a winner. Easy to set up and get working. Amazing speed, sometimes we forget we're editing from an external drive. Extremely quiet, two (10Gb/s) thunderbolt ports on the back - we're thrilled. Solid, well built. Sits on the desktop as 'low profile/out of the way' as you desire. We've been working with the Pegasus2 round the clock for several weeks now and think it'll continue to be a top performer for the long haul.

                          bought two units, one unit worked as advertised, the other unit had problems with shutting down. emailed technical support at Promise. Their response would be great for a programmer or an IT professional but not for me. Time is money and I don't have time to fix Promise's problems. If it doesn't work out of the box send me one that does.

                                I purchased the R4 as a diskless unit and loaded it with 4 one TB Velociraptor drives. Hooked up to my MacBook Pro as a RAID 0 array, Blackmagic tests it at around 800MB/sec. It will eventually be hooked up to my new Mac Pro whenever it comes in, and will be used to store my iTunes movies and music.

                                I've owned an old R6 (Thunderbolt 1) for over a year now, and have yet to have a single problem with it hooked up to my old iMac, so I am very confident in the reliability of these machines. They are expensive, but if you want/need the speed and capacity, it's worth it. They are also very quiet considering the performance.

                                  Bought the Pegasus2 R4 by Promise Technologies. This unit has thunderbolt 2 connection. one word - AMAZING! so far. it's has 4 - 2 TB's drives for a total of 8TB's . I was able to raid 0 two drives for speed and the other 2 drives I left them as independent pass through drives. The raid shows up on my desktop as one drive and the other 2 as single drives. those single drives are hot swappable which is perfect for my lightroom workflow and back up system.

                                  I also purchased the Lacie thunderbolt/USB3 Rugged 256GB SSD bus powered. This drive screams speed. I use this as the work drive for my catalog and files i'm working on at the moment in lightroom. Once I ingest the work I back up the whole file into one of the drives in the pegasus2 system. After several hours of work on the job I back it up again. Great system but it's a bit expensive. All together close to $2000 including tax.

                                    I bought the Pegasus2 R4 to use as primary image and data storage for my new 2013 Mac Pro. As a semi-professional photographer who uses a Nikon D800, I need storage that is fast and vast.
                                    My Mac Pro has not been delivered yet so I have been testing the Pegasus on my 2012 15" Retina MacBook Pro. Blackmagic speed tests show the Pegasus2 R4 is as fast or faster than the internal SSD in my MacBook Pro. Wow!
                                    It's too early to say anything about reliability and durability but, so far everything looks great.

                                      Purchased as storage for a yet to be delivered Mac Pro. Utilizing MacBook Pro now to move all data from old PC's drives. Set-up was a breeze--plug and go. Small utility installation, although no immediate adjustments needed. Box came pre-configured to run RAID 5. Very quiet and fast. Sleeps/wakes well.
