Add RAID 5 storage to your Mac or Windows computer with the ThunderBay 4 Four-Bay Thunderbolt 3 RAID 5 Array from OWC / Other World Computing . As you can guess from its name, the ThunderBay 4 features dual Thunderbolt 3 ports, which utilize the USB Type-C connector. There is also a DisplayPort 1.2 port for connecting up to a 4K display.
The ThunderBay 4 has four drive bays, which supports both 2.5" and 3.5" hard drives (2.5" HDDs do not need adapters). This particular ThunderBay 4 model comes with four 4TBTB 3.5" 7200 rpm drives for a total of 16TB storage capacity. The included drives are configured in RAID 5. With RAID 5, you get protection against a single drive failure. Three of the hard drives are used for storage while one hard drive is used for parity. If you want to reformat to RAID 0 or 1, you can use the included SoftRAID Lite software. RAID 4 and 1+0 are also supported with a RAID software of your choice.
- Thunderbolt 3
- Thunderbolt 3 is a hardware interface that utilizes the reversible USB Type-C connector. Doubling the speed of its predecessor, Thunderbolt 3 features a maximum throughput of 40 Gb/s when used with compatible devices. The connector also transmits data via USB 3.1 at up to 10 Gb/s, and dual-bandwidth DisplayPort 1.2 allows you to connect up to two 4K displays simultaneously. Additionally, you can daisy chain up to six devices from a single Thunderbolt 3 port.
- RAID & JBOD Support
- The ThunderBay 4 comes pre-configured in RAID 5, but also supports RAID 1, 4, 5, and 1+0.
- Time-Tested Cooling
- Built on OWC's time-tested enclosure cooling technology, the Thunderbay 4 utilizes an open "flow-thru" vented design with an over-sized 92mm, low turbulence, noise-quieting fan to keep the drives running cool and reliably.
- Multi-Drive
- Daisy-chain up to six ThunderBay 4s for more storage capabilities and increased performance, or connect multiple ThunderBay 4s to multiple Thunderbolt 3 ports to achieve higher speed capabilities.
- Vibration Dampened
- The ThunderBay 4's drive isolating design reduces sonic resonance and is aided by over-sized, rugged, vibration-absorbing, non-skid feet.
- DisplayPort 1.2 Support
- Dual Thunderbolt ports let you connect the display of your choice that your computer can support, including 4K displays.
- OWC Thunderbolt Cable
- The ThunderBay 4 comes with a 6.6' (2 m) certified OWC Thunderbolt 3 cable.

Euphy works good as new!
Style: 19 Pack
As soon as I opened the package everything looked the same- pre-filters, filters, main brush, and side brushes. I changed the big brush first;the only issue was the new brush body didn't have the white arrows to help aligning but that didn't affect how the brush worked. I changed filter and pre-filter, and finally the side brushes.
When I turned on my "Goophy" and tried to let her run the side brushes were a little too (Goophy's side brushes sounded a little louder). I trimmed the side brushes a little and all was well. Goophy didn't want to run herself but it didn't take long for me to figure out it wasn't the new brushes ;just the operator pushing the wrong button. My Goophy Euphy did what she was supposed to do- vacuum the carpet and tile floor. Goophy Euphy still wanted to take the long way to her charging station which was nothing new and easily corrected.
Over all the new brushes and filter restored Goophy Euphy back to when we first used her!

Don't be cheap like me - buy these and save yourself the hassle!
Style: 19 Pack
I made the mistake of going with another, slightly cheaper set of replacement parts for our Eufy RoboVac 11S. I did not heed the cautionary tales which lead me having to find replacement parts for the replacement parts. This brand fits our vacuum perfectly - the corner brushes don't pop off, the filter is the right size and the roller brush gets sufficiently tangled with cat hair so clearly also a good fit. My only concern (and why I only gave four stars) is - surprise! - the corner brushes. Do they stay on? YES! In fact, they is so secure, I had difficulty swapping one out. Here's the peculiarity of the brand - the "whiskers" on the spinner fell out. I found them all over the floor, on different surface types and under various conditions; they were not getting caught on any one thing. Not all at once, but over two or three uses, one of the corner brushes had become devoid of almost two entire spokes! Ironically, the little guy can't seem to pick up his own mess but I digress. Without the whiskers to grasp, removing the part was difficult. I ended up using a small flathead screwdriver for leverage to pop it off. While the other corner brush appeared to have shed some whiskers as well, it was not in need of replacement. Despite the shedding, this will be my first go-to for replacement parts next go round.

Essential!
Style: 19 Pack
After about 2 months of daily cleanings, the side brushes were looking a little ragged on my Eufy 12. The brushes included in this kit did come out a little bent, but as shown on the product page, when I dipped them in hot water they straightened right out.
Intrigued, I decided to try that with the original brushes. They cam out looking like new!
The only con is that the filters don't look like a perfect fit. The foam seems very minutely smaller than the original and the pleated filter seems slightly thicker.
