## Description

desertcart.com: OWC 2TB Express 1M2 40Gb/s Portable NVMe SSD USB4 (Thunderbolt Compatible/USB-C) Ultra Fast External SSD Drive with Aluminum Heat Sink Enclosure : Electronics

Review: VERY Impressive housing for an external SSD - I've been very impressed with the OWC Express 1M2 (40Gb/s). I was able to very easily install my own SSD and extend the storage space for a new Apple Mac mini while saving several hundred dollars. The OWC Express 1M2 along with the SSD now hold my Apple Home folder and everything is external to the Mac mini. I've got a thunderbolt 4 Mac mini. I opted to go with the 40Gb/s OWC Express 1M2 because thunderbolt 5 speeds in the 80Gb/sec version would have no meaningful impact except for "future proofing". The drive and SSD speeds are great. I've never experienced any transfer speed issues. I've only noticed that the drive/SSD get ejected about every 3 weeks. I'm not sure the cause but am in contact with OWC to find a solution. Other than that, it works perfectly. My OWC express 1M2 is connected and on 24x7. It has a solid build and is always cool to the touch. I would recommend turning the light brightness down when installing any SSD. It's not overly bright but I do see the activity light flashing during the night if I'm awake.
Review: The perfect drive enclosure for an Apple Silicon Mac and the WD Black SN850X ! - I am using this with a 2021 M1-Max Macbook Pro, paired with the Playstation Drive, the Western Digital Black SN850X 8TB ! IMPORTANT NOTE! I had to return the SN850X with heatsink, as you must get the naked version for use with this drive! Due to true Thunderbolt 4 support, this is the fastest external drive I've ever had with my Mac, sustaining 3 GB/sec read+write! Before this, the best I achieved was 1TB/second using those USB 3.2 drives. And unlike with a lot of ready made external drives, this one was easily formatted and partitioned in Disk Utility, with no special hoops to jump through. It's worth addressing that the size issue is absolutely not bad at all. Yes, this is about twice the size of a compact external SSD, but for true perspective, it is smaller than my iPhone 16 Pro, and because it's a sturdy aluminum case, you can stash it as is in your backpack. I use this drive for very large backups, and during my initial backup of a 3.8TB folder, which took over a half hour due to having over 5 million files, the case definitely got hot. Not serious burn hot, but "I don't really want to hold this in my hand" hot. I do not consider this an issue, as future backups will be deltas, and what you get is pure silence. ( There aren't many high performance 8TB drives on the market, but I trust the SN850 to be reliable, due to its extensive track record with the Playstation 5, and it was the second cheapest 8TB SSD I found ). All in all, I think OWC really knocked it out of the park with this external drive! For a single external SSD, this is a no brainer as the best possible choice! :)

### ⭐⭐⭐⭐⭐ Solved my enclosure issues – fast and stable on Mac
*by A***R on December 17, 2025*

I switched to this enclosure after having issues with a cheaper one from China that kept disconnecting randomly. This one completely solved the problem. I’m using it with a WD Black SN850X on a Mac (M4 Pro), and I’m getting around 3000MB/s+ in real-world speeds. Performance has been stable with no dropouts or disconnects. The design looks clean and premium, and the build quality feels solid and well-made. It does get warm under load, but heat management seems well controlled. Overall, this enclosure did exactly what I needed — fixed my original issue and delivered reliable, fast performance. Very satisfied with the purchase.
