Other than that, it shares the same kind of port and cable as Thunderbolt and is also backward-compatible with existing Thunderbolt devices. Note that Thunderbolt 2 is the next generation of Thunderbolt, which offers a 20Gbps connection speed (twice that of Thunderbolt). Other than the black color and the support for Thunderbolt 2, the new Pegasus2 lineup is almost exactly the same as the previous generation. I tested the R8 model, which is very representative of all three. The more drives generally means more storage space and RAID options. The number of drives is the only difference among the three models.

Housing standard SATA desktop hard drives of 2TB, 3TB, or 4TB, the Pegasus2 offers somewhere between 8TB and 32TB, depending on the models. The Pegasus2 family includes three models - the R4, the R6, and the R8 - that can house four, six, and eight internal drives, respectively. The all new Pegasus2 R8 (left) next to the previous generation, the Pegasus R6. It's not perfect, though, since it's very expensive and, in my trial, would take a relatively long time to resume from sleep mode, making it a little inconvenient to use with a laptop.īut the Pegasus2 is definitely a desktop storage solution, and while for most consumers it's overkill, for professionals who need super-fast speed or archiving or real-time 4K video editing, its incredible performance is worth the hefty investment, which is between $1,500 and $4,600, depending on the model and capacities. It almost doubled the performance of its predecessor, as you'd expect from the move to Thunderbolt to Thunderbolt 2. In my testing, the Pegasus2 R8 proved to be the fastest consumer-grade direct-attached storage solution to date. Other than that it's very similar to the previous-generation models.Īs a hardware RAID system, the Pegasus2 supports all RAID configurations available for the number of internal drives it houses, be it four drives (the R4 model), six drives (the R6), or eight (the R8).
Pegasus2 r6 upgrade#
Check back soon for more performance tests using the Mac Pro, Final Cut Pro X, and some competing drives.The Pegasus2 line is Promise's upgrade to the previous Pegasus lineup (including the Pegasus R6 and the Pegasus R4) it adds support for Thunderbolt 2 and an all new R8 model - used in this review - that includes eight internal drives to offer up to 32TB of storage space. We didn’t have time to fully test the Pegasus2 with the new Mac Pro. Blackmagic Disk tests showed 1145 MBps write speeds vs 756 MBps for the first Pegasus and 695 read speeds, a 24 percent faster than the original Pegasus drive. AJA read tests came in at 957 MBps, 45 percent faster than the 659 MBps that the first Pegasus posted. With striped hard drives, the AJA 4K read test showed the Pegasus2 at 1142 MBps, 41 percent faster than the original Pegasus in RAID 0 mode. We then reformatted the six 2TB Toshiba DT01ACA200 drives into a faster RAID 0 configuration and we ran the tests again. Our 6GB large file transfer tests results were throttled by the internal drive in the MacBook Pro, with write tests topping out at 775MBps. Blackmagic’s read result for the Pegasus2 was 698, 19 percent faster than the result posted by the first Pegasus. The Pegasus2 was 31 percent faster than the Pegasus in the AJA Write test and 21 percent faster in the AJA Read test.īlack Magic Disk Test Write results were similar to the AJA results, with the Pegasus2 moving data at a rate of 851 MBps, 25 percent faster than the Pegasus’s 680 MBps result. We moved the drives into a first-generation Pegasus R6 with Thunderbolt and ran the same tests. The amount of data able to move through a Thunderbolt connection hasn’t increased, but the throughput of a single channel has been doubled.
Pegasus2 r6 update#
Thunderbolt 2 is an update to the Thunderbolt specification and takes the original’s two 10 Gbps bi-directional channels and combines them into a single 20 Gbps bi-directional channel.

Thunderbolt first appeared in the early 2011 MacBook Pro, but is now included on all shipping Macs. Thunderbolt combines PCI Express and DisplayPort into a single connection, allowing for a combination of up to six peripherals, like storage devices, and monitors, to be daisy-chained together. Thunderbolt is an interconnect technology developed by Intel in cooperation with Apple. Our initial performance tests show that a single Pegasus2 R6 with 6 standard rotational hard drives can hit speeds higher than Thunderbolt can support, but does not fully saturate the 20 Gbps bandwidth of Thunderbolt 2. The Pegasus2 has a black aluminum case to better match the design of the just-released
