It Definitely Has the Speed, But ...
Drive is installed on a 2011 17" MacBook Pro (8,3) Core I7 2.3 GHz 8 GB.
IMHO, $50 is a little much for a 6 foot cable that oug ht to be included with the drive.
Out of the box, it comes set up for a RAID 5 configuration which gives you 3 TB. Here are QuickBench results with 1.093 TB free:
Transfer Size Large Read Large Write
2 MBytes 620.975 MB/Sec 554.112 MB/Sec
3 MBytes 698.929 MB/Sec 610.119 MB/Sec
4 MBytes 724.439 MB/Sec 610.904 MB/Sec
5 MBytes 766.055 MB/Sec 625.012 MB/Sec
6 MBytes 774.070 MB/Sec 590.093 MB/Sec
7 MBytes 788.594 MB/Sec 613.141 MB/Sec
8 MBytes 808.657 MB/Sec 657.099 MB/Sec
9 MBytes 818.175 MB/Sec 707.836 MB/Sec
10 MBytes 801.079 MB/Sec 622.765 MB/Sec
Large Ave 755.664 MB/Sec 621.231 MB/Sec
... Which is almost 3 times faster than my 3 Gbs SSD.
But first you have to wait 10 hours while it sets up the RAID 5 configuration. Backups from my SSD to the Pegasus are lightening fast. However, I've noticed two problems with this drive. The first and most serious is that when I tried to transfer large folders (> 1 TB) to the R4 from a G Raid drive connected via an esata card, the copy would halt after a few hundred GB and my G Raid drive would be trashed. It did this twice in a row. I was finally able to transfer the files by connecting the G Raid with a FW 800 connection. This is probably an Apple rather than a Promise prroblem.
The second problem is that when using the Pegasus as a boot drive, it's no faster or even slower booting than a regular HDD. My SSD is much faster on boot, but at least you can boot from the Pegasus. I'm going to reconfigure it as a RAID 0 and get 33% more storage than I have now and hopefully a speed increase. …- Written by JOHN M from Tetonia

Pegasus RAID R4
I use this system with my MacBook Pro 17 in 2.3 GHz.
As mentioned in another review it takes over 10 hours of setup time after taking it out of the box and is configured for RAID 5. This leaves 3TB of storage. After testing transfer speeds, it averages around 380 MB/s read/write using the AJA system test.
I have my Apple Cinema Display 30 in monitor via dual link mini-display port attached to the Thunderbolt port on the Pegasus. It does not allow passive transfer via the Thunderbolt port so you must keep the Pegasus on in order to use the external display.
The OWC 3g SSD inside the MBP boots much faster than the Pegasus, even though data transfer is around 240 MB/s by AJA system test.
The OS was updated to 10.7 and seems to run fine on the Pegasus system.
Overall, the system is a little pricey but offers a reliable fast external storage system. …- Written by Adam A from Las Vegas

Fastest Storage Ever Made!!!
This is the fastest external storage device ever made available to consumers period! I transferred my entire iTunes library (182 G B) from my MacBook air (2011) to the promise Pegasus R4 model in 14 min which is crazy fast. Though the Pegasus did not heat up during the process thanks to the duel fans and remained quiet. Also promise kept Mac user in mind with a simple set up and a application to manage Pegasus Which is done for you. This application basically runs Ccheck ups on space, temperature, power, etc. With great power comes great cost, though its worth the money if your going to use pegasus to its full potentioal. Promise also announced they would eventually sell precofigured drives for pegasus- which makes upgrading an option down the road. Being a consumer who is using the Promise Pegasus to store my iTunes library and stream movies from it, it works great. I can watch an HD movie from the Pegasus without any lag, even when skipping around. Buyers be aware that it will take 10 hours to automatically set up/configure the pegasus drives. I just sat back and let it do its thing. All in all this is a product that lives up to its name and is lightning fast. …

Great system / meets expectations
I took delivery of the Pegasus a couple of days ago. It is totally meeting my expectations. I run it with a Macbook Air 2011 and t his combo works flawlessly. Speed is fantastic and faster than the internal SSD hard disk. The R4 is hardly noticeable in a quiet room. I have used the second TB connector to hook up an older Macbook in target disk mode with a Thunderbolt adapter to pull over data.
Buying and setting up the system requires some minimal reading. It seems like not everyone of the reviewers here took advantage of that ...
The Pegasus R4 does not come with a Thunderbolt cable. That is all right if you know about it upfront and can then order the proper length.
Setup is a no brainer. It takes some 10 hours to synchronise, which is properly stated in the documentation. So I started it in the morning and when I came back from work, everything was set up.
If I shut down the Macbook Air with the R4 connected, the R4 properly switches off. And vice versa, the R4 switches on when the Macbook Air comes on. I've noticed a small delay when prompting for Username/Password, when the R4 is connected (compared to a plain Macbook Air). My Macbook Air is encrypted - not sure if this may cause the small delay (approx 5 sec). …- Written by Ivo B from Birmensdorf

Loud and documentation is totally misleading
I don't suggest using this inside a sound studio or anywhere silence is golden. It's too loud for such applications and the longes t Apple thunderbolt cables (2m) are too short to position it sufficiently away from the computer where the microphone is situated.
Three pieces of documentation came with it. The quick start says attach the power, plug in the thunderbolt cable and that's it. No mention of the 10-hour 'sync' time. I can't get a real answer anywhere about what actually is happening during this time. If someone knows, please tell me. Back to the documentation. Then there is a booklet that indicates that nothing will work correctly unless you install some EFI firmware and use a utility CD. No CD came with it so I called tech support. The technician said I don't need to install any firmware and there isn't supposed to be a CD but the utility will be downloaded or somehow available once i connect the unit. Didn't say available where or how I would get to it. Separate from the other pieces of documentation is a flyer indicating that initialization and synchronization can take up to 10 hours.
"When do I install the utility" I asked, "before or after the 10 hours?" Answer: "Before or after." No word on how I will know when the 10 hour 'service' is complete. Now that I've connected and started the unit, I don't see any utility. There is an icon on the desktop but no utility.
And what is this thing doing to my computer during this 'service'?
OMG, this thing had better be worth it! …- Written by mary E from Plano
