Through into a t630 with truenas works great even the warehouse buys are solid.
If you are looking for a replacement/upgrades drive for an older Tivo, this is what you need.

Replaced a total of 4 Tivo drives so far with these, two TivoHD's and two Tivo Premieres. All of them were a snap to image and install and all are performing silently and flawlessly.
Impressed for a 5400rpm

In the past I would avoid WD due to reliability but when I upgraded my Synology NAS i decided to give them another go. Using the benchmark tool in DSM 7 shows that it was just as fast at a 7200 seagate that was used in the old NAS. Honestly can't say if they are quieter, I never noticed the 7200 in previous Synology as loud. Power wise seemed when deviation, but didn't measure it for long and I kept the NAS busy. Best Buy in my area keeps them in stock so easy to run get a replacement if one failed and can't same day an Amazon replacement. Overall I'm pleased with them.
So far so good, quiet and solid.

Bought two OWC units for long term storage onseveral Macs in our small audio and video enterprise. I loaded one of the 4 bay units with four WD Red Plus 14TB drives configured as two Raid 1 mirrored drives. The second unit was configured with just two WD Red Plus 14TB drives also in Raid 1 (two empty bay for future expansion). The assembly was quick after watching one of OWC's installation videos--which probably wasn't needed if like me you've built a computer or assembled an external drive before. As always, follow instructions for installation of both the enclosures and the hard drives. For example, wear a grounding strap when installing the drives. The units powered on immediately and I was able to easily format the units for use with my Mac computers. I chose to forego SoftRaid on either of these units--based on my specific needs at this point, but also because of some of the negative reviews I'd read about the long term cost and reliability of SoftRaid. Both units have run trouble-free for the past month. Besides long term reliability, I was concerned about how quiet the units would be, the amount of vibration I felt (both units sit on desktops relatively close to the computers they are attached to) and operating speed. The units are very quiet and relatively vibration-free. After I assembled the units and attached them to Macs on my network, I had to copy a large amount of data from several Mac and smaller external drives. This took about as much time as I had anticipated and the even with this relatively heavy amount of writing taking place, the units remained quiet and relatively cool. It's too soon to talk about long term reliability but based on reviews of the OWC enclosures and the WD Red Plus (enterprise level hard drives), I am hopeful. I will update my review if my experience suggests otherwise. I think this combination of enclosure and drives provides an effective low cost, reliable long term storage for our video and audio data.
Great for Mac TimeMachine

Installed in a USB3.0 case, very please with performance. Interested readers should look at a YouTube vid by Kore on how to make your own TimeMachine (for iOS).
This is a CMR drive and, in my estimation, superior to a SMR drive. Look it up before you buy a drive.
