Review: Off to a great start. Hoping to get 3-5 years of use on this - I'm a video producer and needed a more long term solution to buy single drives and 2 drive RAIDs over and over. Over the years I've used OWC, Lacie and WD drives so I'm familar with OWC and have never had a drive fail. After some research I decided to purchase this Thunderbolt 3 enclosure instead of a NAS solution (Considered a Synology). I also purchased my own drives (4x 10TB Seagate Ironwolf) instead of the Toshiba drives that are preconfigured on some Thunderbay products. Set up was a breeze and took about 30 minutes. Installing the drives was very easy and the Thunderbolt 3 connection is perfect for my 2018 Macbook Pro. I'll update this review as needed but after using for about a week here are my thoughts: PROS: ✅Very quiet. I was prepared for some fan noise but the combination of the enclosure + 7200 RPM Ironwolf drives works great ✅FAST! I just copied 400GB worth of footage from at Atomos drive in less than 30 minutes. NICE! ✅STURDY. This thing is a beast. All metal construction. Drive trays fit seamlessly. I like the locking mechanism on the front and the flashing light monitoring. ✅SoftRaid XT works great to setup and manage your array of choice. See below as to which version of SoftRaid you should use. CONS: ❌I'm getting some bluetooth interference from the drive based on placement on my desk. It's about 3 feet away from my bluetooth keyboard and trackpad. I need to do some more placement testing to mitigate but bluetooth interference is a known issue with USB3 and (I assume) Thunderbolt devices. ❌It wasn't clear which SoftRaid product to use. From what I gather there is SoftRaid Lite ($49, no RAID 5), SoftRaid ($179, full features) and SoftRAID XT (included with Thunderbay purchase, seems like all features). USE SOFTRAID XT AND YOU DON'T HAVE TO BUY A LICENSE. There's an activation code on the bottom of the Thunderbay for SoftRaid XT. I almost paid for the full license :\
Review: Best Thunderbolt Enclosure I've used - After dealing with a flakey Drobo for years I finally gave up on it and went back to doing JBOD on my Mac Mini. This comes with a SoftRAID license that allows you to run software RAID on this enclosure (the OWC license only allows for managing the OWC enclosure, but can be upgraded to a full license). I do like SoftRAID better than the MacOS software RAID, you can do all the basic's you would expect from a software RAID, plus it's monitoring and allows for verifying and certifying drives to make sure they are functioning properly before using them for your valuable data and on top of all of that it seems to be much faster. One thing to note is SoftRAID doesn't support APFS yet, but since my external drives were still running HFS+ it wasn't a problem for me. I liked it so much I bought a second one, I'm daisy chaining 2 Thunderbay 4's and a 30" monitor without issues off my 2012 Mac Mini's single Thunderbolt port. I like that these have the latest Thunderbolt 3 ports and have a dedicated DisplayPort for a monitor (which I am using). The build quality is great, you can hot-swap drives, and the added SoftRAID software is a plus. I would buy it again, and have already. I've tried a few Thunderbolt external enclosures over the years and this is by far the best I've used on my home Mac.

## Questions & Answers

**Q: Owc 40tb thunderbay raid 5 4-drive hdd external storage solution with dual thunderbolt 3 ports: is this the enclosure only or are the drives included?**
A: Hello!  This product does include the drives.  It would be 4x 10TB drives.

**Q: what is the usuable capacity of the 16tb system in a raid 5 configuration?**
A: RAID 5 takes one drive for redundancy. Since you're asking about the 16TB (4 x 4TB) system, you will lose 4TB (one drive) of storage to redundancy, leaving you with 12TB of useable storage.

**Q: Will this work with m1 mac?**
A: Hello. Yes the ThunderBay will work on a M1 Mac. The version of SoftRAID that this comes with does not work, so you will need to install the beta version of SoftRAID.

**Q: Assume no raid. if i install an independent drive from another drive enclosure, does it need to be reformatted to be used in the thunderbay 4?**
A: Hello. The OWC ThunderBay does not have a RAID controller and uses Software to create raids. That being said you would be able to take an independent drive and installing into the ThunderBay 4 without needing to reformat the drive.

### ⭐ Constant fan noise
*by M***K on June 3, 2021*

It is as far from "whisper" queit as it can get. Obviously, it depends on how quiet your other equipment is and how quiet your office is. This kind of constant noise is not something I want on my table - see video. I returned this device. Not worth the $$$ to me, but yes, it works fine for storing the files and softraid works fine as well. It would be a good solution for a server in another room where I cannot hear it.
