OWC 4TB Express 1M2 Ultra Fast NVMe Thunderbolt (USB-C) External SSD with Aluminum Heatsink Enclosure

I recently purchased the OWC Express 1M2 NVMe Thunderbolt External Drive, and I am beyond impressed! This drive is a game-changer for anyone who needs fast, reliable external storage. The speed is mind-blowing — I'm consistently getting read and write speeds that far surpass anything I’ve experienced with other external drives.The Thunderbolt connectivity ensures lightning-fast data transfer, whether I'm editing large video files or working with heavy datasets. It's perfect for video editors, photographers, or anyone who needs high-performance storage for demanding tasks.The compact design is sleek and portable, making it easy to take with me on the go. I also appreciate the sturdy build quality, which gives me confidence that it's built to last.Setting it up was a breeze, and I had no issues with compatibility on my MacBook Pro and Mac Mini M4. It also stays cool even during extended use, with no noticeable slowdowns or overheating.Overall, this external drive is a fantastic investment. If you're looking for fast, reliable storage with excellent performance, I highly recommend the OWC Express 1M2!

It was quick and easy to add the SSD to the enclosure, had it connected within 5 mins.I also liked that It's solid and reassuring feels weighty. Aesthetically it looks great next to the dark/grey monitor, MacBook and Thunderbolt hub.

Just adding my two cents' worth to the other 5-star reviews. This enclosure is gorgeous to look at, sufficiently heavy to be stable on your desk, and just blows away the competition. I compared it with a slightly cheaper enclosure (also a well-known brand) and this enclosure gives me higher speeds from my 2TB WD Black NVMe SSD. I am getting consistent speeds of 3000+ which is much faster than my Mac Mini M4's internal drive. The enclosure barely gets warm in normal use. It was delivered in just 2 days despite the advertised delivery time being longer, so kudos to the supplier. If you want the coolest, best-looking, fastest enclosure around, spend the extra few quid and get this.

I have recently upgraded to a new M4 Pro Mac Mini from an aging iMac, and I needed a couple of enclosures to hold NVMe SSD’s to replace the external hard disks I used. I tried Ugreen enclosures first, but while the speed was perfectly fine the whine from the cooling fans did get annoying. After living with the sound of the fans in the iMac and external drives for so long I was going for a silent setup. I found a listing for these OWC enclosure’s and after a little wait for them to arrive I am delighted with the performance. Totally silent and the heat dissipation is great. The speeds max out the drive capacity. Very happy with this purchase.

This is just the enclosure although pre-populated options are available. I added a WD_BLACK SN850X 2TB NVMe - very simple installation. Performance has been excellent with both read and write speeds in excess of 3,000 MB/s. No problems so far and the design ensures no overheating. Overall, it is an excellent product.

Combined with the Crucial T500 2TB SSD PCIe Gen4 NVMe M.2 Internal Gaming SSD - it provides a powerful combination. Great transfer speed and hasnt missed a beat so far. Bought 1 month ago. Good quality build.

A little bit pricey but is excellent quality and works very well

Very nicely designed and made, but unfortunately I had to return it as it did not work reliably with my 2024 M4 Mac Mini with the 40Gbps ports on the Mac. It did work at 10 and 20 Gbps, and with other host devices, but at 40 Gbps on the M4 Mini it repeatedly disconnects whenever a high bandwidth operation is undertaken. I can't be sure the fault is with this SSD enclosure and not with the Mac itself, but the Mac works reliably with other SSDs. The problem I've had seems specific to all three 40 Gbps ports being used simultaneously on the non-Pro M4 mini.
