I was replacing an old Mac Pro tower with a new computer that is all display, but no room for storage. I had 4 hard drives inside the old tower, so I put them all into the new OWC enclosure.

The build of the enclosure is excellent. Very solid with lots of vibration dampening.

I migrated my old data from my old bootable hard disk to the new SSD via the Thunderbolt 3 connection. It took about 5 hrs. to transfer 1 TB of data. The Thunderbolt 3 is rated at 40Gb/s. The migration assistant displayed the speed of flow which ran between 35 Gb and 59 Gb. It produced all it was advertised to do.

Noise?. The fan does make some noise. It's not bad. The hard drives themselves make most of the noise as they read or write. The enclosure sits on a desk about two feet from either myself or the computer, so there is going to be some sound.

I'm really happy with it and definitely say it's worth a look.

After two data recoveries from my external hard drive  for my pics nearly lost as a result of crashes/ accidental drops . I needed a better system.
I was able to recover my images, but at a cost.  

I now have comfort and confidence my images will be safe.  Though costly, but as I have said- it's cheaper than a data recovery  ( I was lucky to get them back. )  I no longer worry about losing my pics. Peace of mind is priceless.

PEACE OF MIND

This thing is amazing! I mainly shoot photos but I'm moving into video and my single disk USB 3.0 external (Lacie porche 4tb) was not fast enough for my needs. I first tried out a Mediasonic proraid 4, loading it with four Toshiba 3tb 7200rpm drives in raid 5 and I just wasn't happy with the speeds I was getting in Black magic's speed test. I sent it back and bought this OWC Thunderbay. The Proraid 4 is fine for photos and backup but for speed, the Thunderbay is 2 or 3 times faster. Yes, this is way 2 or 3 times more expensive but you are paying for speed and getting a bonus in the quality of the product. The thunderbay is a very solid build. I raid 5 with the the same drives I got around 200mbps read and write in the Proraid4, in the OWC Thunderbay 4, I'm getting about 520-530mbps.The software was easy to use as well. Only took about 10mins to install the drives and set up the raid 5 once I figured out where the softraid app was.  I definitely recommend this enclosure to anyone working with photos and video. Excellent storage solution.

Super fast!

This is really the best option for those editing on a Mac. No only do you get speeds that are slightly faster than the average SSD, you also get MUCH more storage capacity AND data protection. In my tests with the 20TB version I get about 505MB/s write and 580MB/s read. It's setup from the factory in Raid5 so you don't have to initialize the drives which saves time. In Raid 5 mode (best mode) you get 15TB of usable space as 5TB is setup for data protection. If one of the drives ever dies you slide it out and replace with a new one and you won't loose any data. 

I've been suggesting these to people for over a year now and I'm going to keep doing so. I have a video review of this drive on YouTube if you want to see it in action, speed tests, unboxing, and daisy chaining to a display just do a search for Max Yuryev Thunderbay and you'll find it. The 1.5 to 2.5 times as much. I would recommend it to anyone who needs a fast and reliable drive.
