About Thunderbolt 2
Thunderbolt is a revolutionary I/O technology that supports high-resolution displays and high-performance data devices via one simple port and a cable that carries both DisplayPort and PCI Express data. And it’s standard on every Mac.
PCI Express is the technology that links all the high-performance components in a Mac. And it’s built into Thunderbolt, which means you can get PCI Express speed outside the box.
With Thunderbolt 2 now built into the new Mac Pro and MacBook Pro with Retina display, you can connect up to three 4K displays at once. Thunderbolt 2 gives you up to 20 Gbps in both directions, allowing for super-fast data transfer between peripherals. You also have enough bandwidth to daisy-chain multiple high-speed devices without using a hub or switch.
Thunderbolt also provides double the power of USB 3.0, delivering 10 watts to peripherals for improved performance on the go.

Great match with the new Mac Pro
It did a lot of research and soul searching before diving in with this device. It's a great match with a new Mac Pro. The Thunderb It did a lot of research and soul searching before diving in with this device. It's a great match with a new Mac Pro. The Thunderbolt 2 interface between the two devices is seamless. The Pegasus is configured at the factory for RAID 5, which is what I intended, so I really didn't have to do any configuration on it, except change the default device name for my own purposes. It took about 4 hours to do the initial RAID 5 sync and the system is still available for use during that time. I delayed heavy data transfer from old devices until the sync finished because using the system slows down the syncing process. After plugging in, the Pegasus does need to be attached to the Mac via the Thunderbolt 2 cable (included with the Pegasus). The Pegasus doesn't really come alive until it's attached to the Mac. The configuration utility (downloadable) has gobs of configurables and readouts. Once running, it's very fast. I'm using it for video rendering and this device certainly is not a bottleneck. I'm a happy camper so far! …

Very good, but not perfect
The build quality is excellent, as it should be at this price for desktop storage.
Performance is very good - over 500MB/s stai The build quality is excellent, as it should be at this price for desktop storage.
Performance is very good - over 500MB/s stained on sequential workloads, and reasonable performance on random I/O too. To be fair the random I/O is never going to be a match for SSD with SATA HDD's, but if you want to the drives can be replaced with SSD's.
My only real gripe with this unit is the noise. It's not terrible in a way that Drobo's are sometimes, but it's definitely noticeable. On my desk I also have a Synology NAS located approximately the same distance away on the other side of the desk. I can't barely hear this, even in a very quiet room (late on a night with the clock ticking in the background). I guess I'll just have to buy a longer cable and move the Pegasus further away from me. …

Isn't disk performance, ultimately, the gating factor and not Thunderbolt 2 performance?
- Asked by Carl B from Denver
Technically, in traditional hard drives yes. The reason for this price isn't the thunderbolt 2 alone Technically, in traditional hard drives yes. The reason for this price isn't the thunderbolt 2 alone. It's the many different raid configurations. If you use striping you can effectively pull data close to 600mb/s by pulling the average hdd at 150mb/s across four. The raid enables much higher speed. I'll be utilizing raid 10 which is a nested raid system comprising of raid 1 and raid 0. This will enable about 310mb/s and give me a back up.
The reason this drive system is also very impressive is due to the fact it will allow for 4k video passthrough for daisy chaining while being able to transmit such a high signal. If you want a mac pro and a fast 4k monitor set up with fast data/data back up. This is the way to go.
but once again, if you bought a drive for thunderbolt two, that was a simple single drive system, you would have been correct. …

Are we limited to 2TB HDs, or can 4TB HDs be used
- Asked by Gary S from Chula Vista
Yes, you can use 4*3TB drives or 4*4TB drives. You could, for example, put the installed 2TB drives Yes, you can use 4*3TB drives or 4*4TB drives. You could, for example, put the installed 2TB drives in "transport" mode, pull them out, and then set up a new set of physical drives and then create a new logical set. Please don't, however, take the advice of the user who commented that they installed 5400RPM drives. That would be a waste of the potential speed of this machine. …
