That one would frequently disconnect, and thus it was totally unreliable. I decided to give OWC another chance, and I purchased the ThunderBay 4. I was hoping that it would be more reliable since it uses Thunderbolt 3 rather than USB. And yes...it solved all of my connection problems! I've been using it constantly for several months with my M2 MacBook Pro and an OWC Thunderbolt Pro Dock. It's been working flawlessly. Yeah, it costs a lot more than the 2-drive USB dock, but the reliability is worth it. Pros: • 100% reliable, no disconnects • Solid metal construction. It's heavy! • Thunderbolt connection is fast Cons: • I wish the drives were easier to install and remove. They are held in by screws. I'd rather have a tool-less installation similar to a Synology NAS. • I wish it was possible to close the front panel without locking it with a key. I don't need that kind of security, and now I have to worry about losing a key. Right now I'm just storing the key in the keyhole. That's fine, but I'd prefer not to have a key at all. Those are some minor gripes though. I would still highly recommend this device. I'll give it 4.5 stars, and round up to 5. Review: Works well...noisy - Excellent product...just be aware that the fan is not whisper quiet. Good enough for most work but, because this enclosure sits in my dual purpose edit/mix room, I cannot use an open mic without contamination from the fan noise. None the less, for most users this is a great product. ## Features - 4-Drive SSD Storage Solution with Dual Thunderbolt 3 Ports - Up to 1527MB/s sustained performance - Works with 3.5" or 2.5" drives — no adapter needed - User configurable in RAID 0/1/4/5/1+0 (10) - Ultra quiet, heat dissipating aluminum chassis ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0942YC7Z3 | | Best Sellers Rank | #110 in External Hard Drives | | Brand | OWC | | Built-In Media | Quick Start Guide | | Color | Multicolor | | Compatible Devices | Desktop, Laptop, Mac and Windows with Thunderbolt (USB-C) | | Connectivity Technology | Thunderbolt | | Customer Reviews | 4.1 4.1 out of 5 stars (77) | | Data Transfer Rate | 1550 Megabits Per Second | | Enclosure Material | Aluminum | | Hard Disk Form Factor | 2.5 Inches | | Hardware Interface | DisplayPort, Thunderbolt | | Hardware Platform | Mac, PC | | Item Dimensions L x W x H | 12.99"L x 8.27"W x 10.24"H | | Item Weight | 4.3 Kilograms | | Manufacturer | Other World Computing | | Memory Storage Capacity | 16 TB | | Mfr Part Number | OWCTB3IVKIT000 | | Model Number | OWCTB3IVKIT000 | | Supported Devices Quantity | 4 | | UPC | 810586037129 | | Warranty Description | OWC 3 Year Limited Warranty | ## Product Details - **Brand:** OWC - **Color:** Multicolor - **Hardware Interface:** DisplayPort, Thunderbolt - **Hardware Platform:** Mac, PC - **Product Dimensions:** 12.99"L x 8.27"W x 10.24"H ## Images ![ThunderBay 4 0TB Four-Bay Thunderbolt 40Gb/s RAID Storage Enclosure - Image 1](https://m.media-amazon.com/images/I/61dw6O6hjRL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ An excellent drive dock! *by J***O on December 7, 2024* Previously I had an OWC Drive Dock that held 2 drives, and it had a USB connection.

Good enough for most work but, because this enclosure sits in my dual purpose edit/mix room, I cannot use an open mic without contamination from the fan noise. None the less, for most users this is a great product. ### ⭐⭐⭐⭐⭐ Works Great *by J***C on January 9, 2026* Works as expected. Speed is good and drives are easy to swap in and out. You can hear the mechanical drives in it but I don't find it bothersome. It has more to do with how noisy a drive is itself than the enclosure. ## Frequently Bought Together - OWC ThunderBay 4 with Dual Thunderbolt 3 Ports (0GB) - OWC Thunderbolt 4 Cable, Thunderbolt Certified, 2.0 Meter (6.56 ft.), 40 Gb/s Data Transfer, 100W Power Charging, Compatible with Thunderbolt 4, Thunderbolt 3, USB-C, and USB4 Devices, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/427599761-thunderbay-4-0tb-four-bay-thunderbolt-40gb-s-raid-storage](https://www.desertcart.co.za/products/427599761-thunderbay-4-0tb-four-bay-thunderbolt-40gb-s-raid-storage) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-05-28*
