Review: The BEST SSD Enclosure for Creatives – A Must-Have for Mac Users!!! - 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!!!
Review: Probably the best USB4 enclosure - UPDATE: Still the best enclosure! Had a Predator GM7000 lying around and the 1M2 was once again the only USB4 enclosure that worked with it. It's the only USB4 enclosure good enough I bought it twice TL;DR: The OWC 1M2 is really good because it runs the coolest and is super reliable. The only downside is that replacing the SSD is a hassle once it’s seated inside. I’ve owned the Konyead, Zikedrive, Satechi, and Ugreen USB4 enclosures before purchasing the 1M2. I think the OWC 1M2 is the best out of the five, though not completely perfect. Quick explanation as to why I own all these: I work in film, and transferring multiple terabytes is common. USB4 drives let you do that extremely quickly. The only options for USB4 drives (as of writing) are the SanDisk or Glyph Pro series, which are horribly overpriced (and in SanDisk’s case, even destructive), or enclosures with the asm2464pd controller, which is currently the only one designed for USB4. While these enclosures aren’t cheap either, pairing them with an SSD like the WD SN850X, which has dropped massively in price, gives you fantastic speed for the cost. The OWC 1M2 is really big—bigger than even a 2.5" SATA enclosure (pictured in the second photo). USB4 enclosures are already large by M.2 enclosure standards, mainly for heat dissipation. PCIe Gen 4 SSDs can run as hot as 80°C or even 90°C if you’re using the SN850X, but the 1M2 excels at cooling. The entire enclosure is covered in large fins, and none of my other enclosures come close. Here's why that matters: all my other enclosures get very hot under load. The 1M2, being so over-the-top with cooling, only gets warm to the touch. That’s a huge win. With the others, I have to wait for them to cool down after big transfers. The 1M2 is always cool enough to keep going. In my setup, I use 4TB SN850X or FX900 Pro SSDs. For some reason, the only enclosure that works perfectly with the FX900 is the 1M2. I believe manufacturers write custom code for the 2464 controller, and OWC has written the best code for SSD compatibility. Moving between Windows and macOS, the 1M2 never drops a connection and handles full drive writes really well. The only other enclosure I own that’s equally reliable is the Zikedrive. The Satechi and Ugreen have some rare, forgivable edge cases, while the Konyead is basically toast. I also appreciate that the 1M2 came with reasonably new firmware for the 2464 controller, unlike the others, which I had to update. My only complaint is the design. Out of all the enclosures, the 1M2 seems the least portable. It has large rubber feet on the bottom, and unlike the others (except the Konyead), it’s designed to be upright only. That’s fine, but the annoying part is the screws—hidden behind the rubber feet that you have to tape on yourself. So, once your SSD is seated, replacing it requires removing the rubber feet and unscrewing everything again. Definitely make sure your SSD works 100% before taping the thing shut!

### ⭐⭐⭐⭐⭐ 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! :)
