OWCExpress 1M2 Portable NVMe Thunderbolt (USB-C) SSD USB4 Ultra Fast External SSD Drive with Aluminum Heat Sink Enclosure (Enclosure Only)

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.

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

Unfortunately i bought the wrong drive size (1tb) was after a 2tb so had to return. But it looks fabulous.

There are multiple versions of this device with 1TB, 2TB, and 4TB SSDs pre-installed or you can buy a version which is an empty enclosure in which to put your own SSD. I purchased the 1TB version.This device is advertised as delivering 3000MB/s for both reads and writes when connected to an M1 (or later) iMac. Having tested the device with my own M1 iMac, I can confirm that it does achieve 3000MB/s reads, but it would only achieve slightly less than 1000Mbps write speed (see screenshot) with my iMac.If you aren't worried about the speed of data transfer, there are much much cheaper SSD enclosures available (e.g. Sabrent do a metal USB-C SSD enclosure which I bought on Amazon which is much smaller, runs much cooler and only costs about £10, but then it only delivers slightly less than 1000Mbps reads and writes).As I wasn't getting the write performance I was expecting from this OWC Express 1M2, I decided to return it. To be fair, I have seen other reviews which show this device achieving 3000 MB/s writes so perhaps I was unlucky or perhaps it is just an issue with M1 iMac compatibility.A couple of other points to note:1. The case of this device does get very hot when in use.2. The versions of this device supplied with an SSD pre-installed do not appear to be upgradeable as the case appears to be sealed with the SSD already inside. If you want to buy an OWC Express 1M2, you may be better off buying the version which is an enclosure only and putting your own SSD in it. That way you can always change the SSD if you want one with greater capacity later or you can replace the SSD if it fails without having to junk the enclosure as well.In summary, this isn't a bad device. If you are primarily interested in read speed, then this device is extremely fast. If however, like me, you have an M1 iMac and you want something that has a fast write speed as well, based on my experience of it, you may be better looking somewhere else.
