Ratings & Reviews
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. …
