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! :)
Review: Solved my enclosure issues – fast and stable on Mac - 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.

### ⭐⭐⭐⭐⭐ The BEST SSD Enclosure for Creatives – A Must-Have for Mac Users!!!
*by J***H on August 9, 2025*

If you’re like me and edit photos and videos for a living while also not wanting to overspend on Apple’s higher storage tiers, this is a godsend! My previous enclosure for a 4TB SSD was an ORICO 40Gbps model with a fan. It was among the first of the 40gbp models at the time, but problems began immediately when using it on my Mac. It would disconnect multiple times, only stopping after I manually ejected and reconnected the drive. This put my video and image files at serious risk as anyone in our line of work would know, but I brushed it off as a design quirk until I discovered the real issue. Overheating. The ORICO would get so hot that it could literally burn you if you touched the metal top of its plastic shell. My breaking point came when, in the middle of an edit in Final Cut Pro, the drive disconnected yet again. That was when I decided to cut my losses, wrap it up, and search for the fastest, most reliable solution i can find. I'm happy to say that search ended with this OWC enclosure and honestly, I couldn’t be happier. Not only does it do exactly what it’s supposed to, but I can finally work without worrying about disconnects or losing my files. The solid metal body and finned design act as a massive heatsink, pulling heat away from the SSD and dissipating it naturally. This keeps the drive safe from overheating, prevents thermal throttling, and ensures I can take FULL advantage of my SSD’s maximum performance. Also while yes it goes get warm, you won't have to worry about burning yourself like the old drive I had. All this mind you, is working without a fan! That's how good the heat management on this thing is! Design-wise its's perfectly matched to my M4 Pro Mac Mini setup, it's small, and lightweight. You don't need extra software or drivers that are needed to run it, you just plug it in and it shows up as a storage device on Mac. The only setup required on your end is applying the thermal tape so it makes solid contact with both the SSD chips and the enclosure. It's nice and thick so you know its going to make full contact on both parts. This is my first OWC product, and it certainly now won’t be my last. If I could give it 10 stars, I would!!!
