Review: Incredible Speed and Performance! - 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!
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.

### ⭐⭐⭐⭐⭐ Fast, stable and easy to set up but costs more than alternatives that will probably do the same job.
*by E***E on 5 September 2025*

I was going to buy an M4 Mac Mini dock but I have all the plugs I need so went for just an SSD enclosure. Fitted with a Samsung 990 Pro that is faster than the OWC supports but the SSD was on offer so went for it as it was less costly than a slower alternative. The enclosure is a doddle to set up and use and I now have all my key programmes - MS Office and Photoshop, Acrobat and Lightroom plus Chrome and Firefox running from it. Fast? Seems to be. Stable? Yes. Fast file transfers? Extremely quick. Does it run hot? Gets warm under load, hence sitting on heavy alloy billet which really helps reduce the running temperatures. Not a problem without but in hot weather is could be. Older and slower SSDs run cool. Fast ones are clearly using a lot more power and do run warm. If the Mac is left to sleep the external drive is warm to the touch in the morning. This is normal I am told. Would I run this with a 'laptop'? If the laptop is plugged into the mains, yes. But I think these powerful SSDs and enclosures eat power so be aware if you want to use battery power for an extended period. Would a cheaper alternative be as good? No idea. I buy something that has a good warranty from a trusted supplier. Do I trust my data to an SSD? No. I have multiple back-ups and always save pictures from my SD card to at least three external drives. Two Samsung SSDs have died on me but they were lower capacity and worked really hard. Can I plug in the drive and use it with another computer? If it is a Mac with an M1 to M4 chip and fitted with USB 3/4 or Thunderbolt yes. Works seamlessly. Would I recommend? If you rely on an external drive, yes. Would I fit a slower SSD? Yes, a Gen 3 will be just as fast as the Gen 4 SSD I bought. Do I need my 'home made' heat sink? No but have used this system for a long time and it works.
