Product Information

  • Overview

    The premier storage choice for creative audio/video professionals and multimedia enthusiasts around the globe, the PROMISE Pegasus2 now can deliver even faster performance with the new 20 Gb/s Thunderbolt 2 technology, while assuring enterprise-class reliability and ease of use.

    Use your hard drives from your old Mac Pro

    The Pegasus2 R4 Diskless System allows existing Mac Pro users upgrading to the newest Mac Pro model to migrate current storage seamlessly. Simply remove your drives from your current Mac Pro and reinstall into the drive trays of the Pegasus2 R4 Diskless system to get instant access to all of your data. Most drive models shipped with the Mac Pro line are qualified with Pegasus2. (Please refer to the Promise compatibility list for supported drive models.)

    Blazing speed for 4K workflows

    The Pegasus2 is the fastest Thunderbolt 2 storage solution available, delivering raw power for audio/video/graphics amateurs and professionals alike to manage and edit multiple compressed 4K streams.

    Simple, flexible, and cost-effective backup solution for home use

    Fast, safe, and reliable external storage is essential when protecting your valuable files such as music, photos, and videos. The hardware RAID capabilities of the Pegasus2 family protects all of the memories that were meant to last a lifetime that could be impacted from single drive failures, while simultaneously providing data protection and high reliability. The Pegasus2 family provides fast performance for popular applications such as iTunes, iPhoto, iMovie, GarageBand, Photoshop, and media center applications. Backup your irreplaceable digital media, documents, and also your entire computer or workstation to Pegasus2 with Time Machine in OS X.

    Enterprise-class RAID protection

    Once your data is cleanly backed up elsewhere, the drives in your Pegasus R4 Diskless System can be reconfigured as a RAID volume. Pegasus2 features enterprise-level RAID storage protection for your data, supporting a broad range of RAID levels as well as automatic error handling.

    About Thunderbolt 2

    Thunderbolt is a revolutionary I/O technology that supports high-resolution displays and high-performance data devices via one simple port and a cable that carries both DisplayPort and PCI Express data. And it’s standard on every Mac.

    PCI Express is the technology that links all the high-performance components in a Mac. And it’s built into Thunderbolt, which means you can get PCI Express speed outside the box.

    With Thunderbolt 2 now built into the new Mac Pro and MacBook Pro with Retina display, you can connect up to three 4K displays at once. Thunderbolt 2 gives you up to 20 Gbps in both directions, allowing for super-fast data transfer between peripherals. You also have enough bandwidth to daisy-chain multiple high-speed devices without using a hub or switch.

    Thunderbolt also provides double the power of USB 3.0, delivering 10 watts to peripherals for improved performance on the go.

    The Promise Pegasus2 R4 is a great device. It's not the smallest or quietest Thunderbolt RAID enclosure (though it's by no means l The Promise Pegasus2 R4 is a great device. It's not the smallest or quietest Thunderbolt RAID enclosure (though it's by no means large or loud), but it's definitely among the fastest. It's also highly versatile - each disk can either be used independently or as part of a disk array (RAID 0, 1, 5, 6, or 10) and easily handles I/O that brought my old Drobo to its knees.

    That said, I suspect that the "diskless" Pegasus2 was probably somewhat rushed out, which led to some annoyances setting the device up. The process of adding hard drives is quite easy: just put the drive in the sled, secure the four screws, then slide into the Pegasus2 and latch into place.

    However, all four drives show up as separate drives attached to the system. To combine them into an array, the Quick Start Guide says to consult the Product Manual, which is not included in the box. You can find it online if you're interested, but the short of it is that you need to use the Promise Utility. Normally this is included on the drive, but since this is the diskless model, it, too, must be found online. I can't provide a link here, but just search the internet for Promise Utility 3.18.0000.18 and you should find it in Promise's Download Center.

    Once the Promise Utility is installed the fastest way to get started is to use the Wizard. After the array is set up you should be good to go.

Just as advertised, plugging in the four disks from my old Mac Pro worked well using the Thunderbolt port on my Mac Book Pro. I haven't used it long enough for an in depth review but so far I'm very pleased. It's fast and very quiet. The fact that it was diskless was a big bonus.

    I've been using it for about a week now with a pair of 3TB Hitachi Deskstars (HDS72303) in JBOD mode (called "Pass Thru" by Promis I've been using it for about a week now with a pair of 3TB Hitachi Deskstars (HDS72303) in JBOD mode (called "Pass Thru" by Promise) transferred directly from an old Mac Pro. No problems at all, except that Promise doesn't include mounting screws for the hard drive sleds; the big head screws from the Mac Pro protrude from the side of the sled and prevent it from sliding back into the unit, so be sure you have small/flat head mounting screws. I'd read about power management issues with this unit, but it's been perfect through multiple sleep/wake and on/off cycles. Very pleased so far.

The performance goes up when you stripe them, but you don't have redundancy in that configuration. I'm very pleased with this product and highly recommend it. Did I mention its whisper quiet and goes to sleep/shutdown when the computer attached is in either states? the mac osx utility is also elegant and works seamless with a wizard and monitoring tool.

I had spent a great deal of time researching enclosures and it seemed the best. I backed up all my data and put 4 4TB drives in and migrated my data from my old Mac Pro. I am very pleased. I use this with my 6 core Mac Pro. It is very fast. I had been using an external drive with USB3. There is no comparison.

    Be sure to download the utility from Promise. It has nice features and is straight forward. I read the manual cover to cover so I felt comfortable with the device. It has performed perfectly. It is thrilling to have my 120K images so easily accessible. The fan is audible on the scale of my old 2006 Mac Pro. I will put the enclosure in a sound proof ventilated case.

    It makes the Mac Pro a real thing of beauty.

They work great when you first get them. Then a drive bay will keep failing a drive every 3 months or so. I have changed 4 drives in the same bay and Pegasus refuses to acknowledge it is the housing with the issue. Look elsewhere. You have been warned.

    I will gladly unload this thing for half what I bought it for.
