If you were to get SSDs separately, you can get 1TB drives for about $500 for 1TB so say you get an 8-bay enclosure for $1500 with no drives and 8x $500 1TB SSDs, that's $5500 vs $1500, then SSD is 3.5x more.

Two of them on a chain in RAID0 runs at 2GB/s write, 2.5GB/s reads. Lacie's Thunderbolt 2 drive shows the performance possible:Ī single drive with dual SSD blades up to 1TB runs at 1.1GB/s write, 1.3GB/s reads. It's only SSD drives that get the benefit of Thunderbolt 2 so the Pegasus would have to be filled with those. But it wouldn't be necessary to do this even on a MBP as they have two Thunderbolt 2 ports.

A 4K display would need 3840 x 2160 x 60Hz x 24-bits = 11.9Gbits/s or 1.5GBytes/s.

Thunderbolt 2 is not really needed for a drive like this but it does mean you'd be able to put a 4K display on the same chain. Those with a Mac Pro have little to worry about here, but MacBook Pro owners may find diminished bandwidth depending on setup and workflow. 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. This is more than enough bandwidth to edit full resolution 4K video in real time. In our tests the logical drive clocked in with speeds up to 540MB/s read and 454MB/s write, while real-world sustained speeds came in at just below 300MB/s. Pegasus2 lives up to the Thunderbolt 2 hype.
