Review: I Wish I'd Known About This Before I Returned Others Like It - I've bought a few different external drive systems over my lifetime, but none as quality on par as this chonky boy. It is thicc, you may notice the same thing, but I'll tell you why it's for good reason. I purchased the 0TB version of the OWC Express 1M2 SSD enclosure and I paired this up with a Samsung 990 Evo Plus. My needs for more hard drive space was quickly realized when the base Mac mini M4's measly 256 GB of storage wasn't gonna cut it. #basemodelgang The premium quality straight out of the box was noticeable in my hands. Heavy. It feels well made and the aluminum reminds me of an expensive tool. It looks cool, I think. Matches the color of my Mac enough. All the fins, slices, across the top of the enclosure allow a massive amount of heat to be dispersed passively. No fans, no noise. And it works well! I have noticed it gets warm to the touch, but nowhere near concerning. It supports PCIe 4.0. It's not the most portable SSD, I will say that is a downside, but it can be for the occasional need. I like that it's thin enough to slide into the front pouch of a backpack. The better part of this setback, is that it allows me to edit videos in Final Cut Pro directly from the drive right as it sits on my desk. Quietly operating, without a sound. It's fast, faster than anything I've used and almost double to internal Mac mini read/write speeds and averages above 3,000 for both. I think this product is for someone who wants to expand their computer with more storage, but doesn't mainly travel with it. If your priority is portability, you may already know this isn't for you. The things that make it not so great option to carry, are the exact reasons you want it when performance and sound are what you are looking for in your search for an external hard drive.
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.

### ⭐⭐⭐⭐⭐ The perfect drive enclosure for an Apple Silicon Mac and the WD Black SN850X !
*by J***I on July 6, 2025*

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! :)
