Promise Technology R8 overview

  • 1Description

The Promise Technology 24TB Pegasus2 R8 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 R8 stores up to 24TB of data spread across eight 3TB 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, 10, 50, and 60 are also supported; each level offers configuration options for capacity, data protection, redundancy, and speed.

The Pegasus2 R8 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.

    Promise Technology R8 reviews

    24TB Pegasus2 R8 Thunderbolt 2 RAID Storage Array is rated 4.8 out of 5 by 11.
    Rated 5 out of 5 by from Big storage, fast speed, great price I was moving from a 2007 Mac Pro to the new 12 core Mac Pro and the Promise 24TB is the best choice for my working RAID. The unit comes set as Raid 5 which is great and all I had to do was plug in the thunderbolt 2 cable and let it run through its scan. The scan takes a while but once done you are ready to work at flying speeds on the new Mac Pro with thunderbolt 2. You won't find a better Raid with thunderbolt 2 for the price.

    Rated 5 out of 5 by from Fast, Fast, FAST!!! Right out of the box we're getting 790 write and 980 read. Amazing. Remember when a RAID system cost 10k and was only 1/4 the speed? 3 4K streams at 1/2 res in realtime through FCP. Love it.

    Rated 5 out of 5 by from Awesome It boots out of the box and read-writes 3x as fast as my other RAIDS.

    Rated 5 out of 5 by from Great performance I work as a Post-Production Supervisor at a production company where we are constantly having to expand our storage as new project fill up our drives. This is the third Pegasus RAID we've purchased this year and just like the other two it performs better than anything else we've tried before. The speed from Thunderbolt 2 is amazing, and it's silent operation makes it perfect in almost any situation. I would highly recommend this for anyone looking for a professional RAID for a 4k workflow.

    Rated 5 out of 5 by from Great product I use it mostly for my photography. I have over 300,000 RAW photos and the response is great and easy.

    Rated 5 out of 5 by from Perfect: 24TB Pegasus2 R8 Thunderbolt 2 RAID Storage Array This is my third Pegasus RAID I've purchased. I've had good luck with these RAIDs. Although, this particular R8 RAID had Disk #1 die only after 30 hours of use. Luckily, I used RAID 5, so I did not loose my data. I have to admit that Promise Technology's support was absolutely perfect! The agent took over my computer, did his magic, filled out a replacement order, and put my simple mind at ease. Next-day shipping delivered another Disk #1 to my door. Installation and rebuild was a snap. I know it sounds shakey for a drive to die so soon after purchase. But if you need, this caliber of RAID, you already understand that stuff happens. I have no complaints about this RAID, and only praise for the support team! Plus, it doesn't get any better than B&H!

    Rated 3 out of 5 by from Mixed feelings but we'll see I researched a lot of different options over the span of several weeks before going with this model. At this point I think it should be a requirement that all preconfigured RAID storage devices indicate exactly which hard drives they come with (brand, model name and model number). The drives that came with this turned out to be some of the cheapest on the market and are known for failing sometimes with very limited use. I wasn't able to compare to a diskless model since they only come pre-configured with drives. Each of the drives in this run a little over $100 USD if purchased separately for these 3TB Toshiba drives. Subtract that $800 to $900 from the total price of this 8-bay RAID box and that is the base for the diskless RAID box. Compare that to other diskless RAID boxes on the market with all other specs being the same or similar and this one costs WAY more. The one feature that the others didn't have, however, is comparable RAID utility app. Most are clunky servers and browser or command line based. I haven't seen a utility app for any other RAID storage (NAS or Direct connect) that comes close in usability / simplicity / clean GUI.

    Rated 5 out of 5 by from Worked out of the box as described I find the Pegasus a very easy to configure device. We've had the R6 for a number of years, and needed the extra storage that the R8 offered (along with its ability to double the drive size if we need to do so in the future).
