SANLink2, a Thunderbolt 2 to 8Gb Fibre Channel bridge, alleviates storage bottlenecks for desktop and portable computing systems by providing direct connectivity to an external Fibre Channel Storage Area Network (SAN) such as a VTrak x30 RAID storage system or a shared SAN filesystem for rich media video ingest and editing such as a VTrak A-Class.Īs one of the storage industry’s global leaders, PROMISE is the developer of high-performance solutions optimised for the video bandwidth requirements of the media and entertainment market and is the leader in developing cutting-edge Thunderbolt enabled devices. The Pegasus2 line of hardware RAID solutions provides blistering-fast transfer speeds that dramatically accelerate and simplify 4K workflows and offers industry-leading RAID protection in a sleek, compact, and portable enclosure at maximum Thunderbolt 2 data transfer rates. today announced Pegasus2 and SANLink2, the world’s first storage solutions with Thunderbolt™ 2, the revolutionary technology from Intel® that delivers blazing speeds of 20Gbps and allows for exceptional performance for creative workflows and 4K streaming and display environments. dmg from an external DVD reader at the same time to another external drives attached to a different USB3 IO, I could not be bothered to wait for it to finish but it doesn't seem to have caused any slowdown on the RAID.įor TB 1 there is a nice dock here but a lot more $s than a USB3 dual dock mentioned above, if you don't need the extra speed USB3 is pretty nice.īut of course you can't have RAID 5 with two drives but you can have a RAID 0 for non critical work such as capturing HD video etc.New Thunderbolt 2 Solutions Deliver Unprecedented Performance and Flexibility to Creative Professionals and 4K Workflows.

By the way the Mac Pro (a 6 Core 2013) was also creating a. Not much use for editing 4K maybe but pretty snappy I think you would agree. This all took about two minutes start to finish. In the meantime, to answer your question, I bought a $35 EZ Dock dual bay USB3 dock on Amason, used a couple of SATA 3, 7200, 2 TB drives I had lying around and used Apple Disk Utilities to create a 4 TB RAID 0. I am waiting for prices to come down and more options to go TB2 RAID. This doesn't have much to do with USB 3 vs Thunderbolt, there are cheaper Thunderbolt drives too: A single SSD over USB 3 is actually faster than this HDD Pegasus over Thunderbolt. USB 3 is fine for single drives as it is roughly as fast as the SATA connector and especially HDDs as they are about 1/5th that speed. Sure, TB is much faster than USB, but both are MUCH faster than any single HD, right? But will I notice any performance difference at all? USB has the advantage to working with practically any computer, as well as being far less expensive. So for those of us who simply want to add some external storage, say a single 3.5" 2TB 7200RPM, do we need Thunderbolt? Or is USB3 fine? 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.
