Review: Turn an NVME SSD into a high-performing external drive - UPDATE: note for dock users - If you already have an NVME SSD to hand, this is a cheap(ish) way to turn it into a high performing Thunderbolt external drive. With a WD Black SN770 2TB SSD (pulled out of my desktop PC) inside and connected to my M4 MacBook Air, I can get over 3GBps read and write on this drive - probably difficult to get faster reads and writes than that with an external drive I'd reckon. Mounts fine every time and seems stable - doesn't disconnect when laptop goes to sleep. It was pretty easy to install the drive and it's even supplied with rubber feet for you to install over the screws once you've got the drive installed. The enclosure looks good and keeps the drive relatively cool - it gets warm, but never hot to the touch (even after hours of use). UPDATE: using with a Thunderbolt dock. I tried using this enclosure with several Wavlink Thunderbolt docks, and with each of them the drive only performed in USB 3.2 mode, achieving reads/writes of around 1GBps - much slower than if connected to the Mac directly. After some research, it transpires people using this enclosure with other docks (CalDigit TS4, mainly) were having the same issues. Talking to OWC's tech support over email (they responded quickly), I asked if their docks would enable the enclosure/drive to perform at USB 4 speeds. They said yes, so I bought the OWC 11-port Thunderbolt 4 dock and it worked. You won't get quite full performance when using a dock, but I am getting over 2GBps reads and writes (almost 3GBps reads) via the OWC dock and am happy with that. So if you are intending to use this drive with a dock, or wondering why it doesn't perform optimally with the one you're using, my recommendation is to (unfortunately) shell out for an OWC one.
Review: Is there any better enclosure at these speeds? - Not sure you can do better than this enclosure at this price. It’s fanless, so it’s entirely silent during operation and you don’t have to worry about the fan failing, which is huge double bonus. This should literally last as long as the components inside it do, with no other point of failure. Built with maximum efficiency so it stays at safe temps even during prolonged use. It’s rock solid, build like a brick, feels premium and high quality and has never gotten too hot to touch, only very warm when in use. It is a heat sink so it gets warm even when idle but that’s expected. It fell off my shelf (about 8 inch drop onto hardwood floor) with ssd installed and no affect on performance, not even a scuff! Every other enclosure I researched either had a fan (noise, point of failure) or had sketchy prolonged temps. This is the only one I found that does everything you could want an enclosure to do. It’s rare to find a product that has no discernible con or trade off, but this might just be it! Paired with a 990 Pro on MBP for gaming and works like a charm. It’s half the speed of the 990 Pro so will look at getting a faster enclosure in the future to unlock max SSD speeds. Until then this does everything it needs to.

### ⭐⭐⭐⭐⭐ Top Quality in both Build and Performance
*by A***N on 21 September 2026*

A lot of reviews go into detail about transfer speeds, so I'll treat that as covered. Let's cover other aspects ... The OWC Express 1M2 is roughly the same size as other 40Gbps enclosures but maybe a little wider or taller. It's a solid chunk of aluminium, beautifully finished and clearly designed to dissipate heat easily with that array of fins. One much appreciated feature is the activity LED being placed right on the front where it's easy to see - and it's large too. Other brands seem to go for a pin-hole next to the USB-C port, which ends up at the back in a desktop configuration. The quality of finish is superior to most with the join between the two 'halves" so clean that it's barely visible beyond just a very thin line. When you remove the two screws holding the halves together it's initially hard to pull them apart. This is because the main controller chip has its own little silicon heat pad making contact with a protrusion on the main aluminium body. Gentle prying pulls it free. The other end of the base is located by lugs into a groove in the top. You get three foam "feet" to cover the screws. Only one is needed but the spares are good for any SSD swaps in future. In use the drive is certainly fast, even with a more modest NVME SSD such as the one I am using - a Crucial P3. Professional video and audio editors probably need all the speed they can get, but I'm not in that league and find the enclosure easily fast enough to run external applications from. Incidentally, you can in some way control the heat generated by choosing a cable rated at less than full-speed. I commonly use a good quality 10Gbps or 20Gbps cable instead of TB4 or 40Gbps and find the file transfer experience still excellent and generating little heat in comparison. The case only gets gently warm. You can of course, swap cables as required. Not a big deal and for non-critical use you put less stress on the SSD. As for value for money, you get the quality you pay for with the OWC and having used many lesser enclosures in the past I'm happy to have made the investment. It seems I'm an OWC convert.
