Pegasus2 lives up to the Thunderbolt 2 hype. As such, we'd also like to thank B&H Photo for its help in securing one. We were fortunate enough to test the 8TB Pegasus2 R4 for several weeks, but the drives were initially hard to secure.

You can also check prices daily in AppleInsider's Mac Storage Price Guide. This will account for an additional $115 to $350 in savings, depending on the model. These are currently the lowest prices we could find for these drives, with the added benefit of no sales tax outside of NY. Promise's larger R6 comes in 12TB and 18TB configurations and sells for $2,230 and $2,900, respectively. The 8TB Pegasus2 R4 retails for $1499 and is currently available for $1,454 complete with drives pre-installed.

With Thunderbolt 2, accessing mass storage is no longer the bottleneck for professional workflows.

Those with a Mac Pro have little to worry about here, but MacBook Pro owners may find diminished bandwidth depending on setup and workflow.įor many users, the Pegasus2 can be a completely plug-and-play machine for file backups, Time Machine saves and multimedia storage, though the product's real power lies in its ability to access huge amounts of data at high speeds. When using a 4K monitor, however, the story changes somewhat considering the available pipeline will be mostly reserved for pushing pixels. Read and write speeds did not come close to hitting Thunderbolt 2's 20Gbps barrier. Thanks to the Mac Pro's six Thunderbolt 2 ports and three buses, we were able to drive Sharp's gorgeous 4K monitor on one bus while keeping the Pegasus2 routed separately for maximum throughput. The biggest of the bunch, the eight-drive Pegasus2 R8, is capable of RAID 60, otherwise known as RAID 6 + 0. The R4 can handle RAID 0, 1, 1E, 5, 6 and 10 (1 + 0), while the larger R6 and R8 support RAID 50 (5 + 0). Promise pre-configures its Pegasus2 arrays from the factory in RAID 5, a "best of both worlds" level that offers good speeds and redundancy across the four physical drives. On the Mac Pro, we left the "put hard drives to sleep" option unchecked, thus defaulting the R4 to the Promise Utility software's settings. For example, when we left the array attached to our 2013 MacBook Pro with Retina Display, Mavericks would spin the drives up when Power Nap was enabled. It should be noted that OS X will recognize the R4 as a single logical drive, meaning the global Energy Saver settings in System Settings apply. The process takes quite some time to complete - in our case a little under five hours - and mileage will vary depending on storage size. Not a huge difference, but the change is a nice touch that keeps with Apple's new all-black aesthetic seen with the Mac Pro.Ī warning note comes with the unit, instructing users that their new array must be plugged in and attached to a host computer in order to properly build the logical drive. The Pegasus2 is identical to the previous generation Pegasus save for a color swap from silver to matte black. Pegasus2 also comes in 6- and 8-drive configurations with support for 2.5-inch SSDs as well as 2.5-inch and 3.5-inch Hybrid HDDs. The version we tested, dubbed the R4, comes with four 2TB 3.5-inch 7200RPM SATA drives preinstalled in our case units from Toshiba. Promise changed that in December when it launched the world's first Thunderbolt 2 RAID array.īuilt around the PMC Sierra 8011 RAID-on-chip processor, Promise's Pegasus2 controller comes with 512MB of DDR2 SDRAM to push data through Thunderbolt 2's bi-directional 20Gbps channel. Apple's late-2013 MacBook Pro with Retina Display was the first computer to incorporate Thunderbolt 2, but at the time there were few accessories that supported the technology. Following Intel's announcement of Thunderbolt 2 in January 2013, products harnessing the super-fast transfer protocol are finally coming to market.
