With a WD Black SN770 2TB SSD (pulled out of my desktop PC) inside and connected to my M4 MacBook Air, I can get over 3GBps read and write on this drive - probably difficult to get faster reads and writes than that with an external drive I'd reckon.Mounts fine every time and seems stable - doesn't disconnect when laptop goes to sleep.It was pretty easy to install the drive and it's even supplied with rubber feet for you to install over the screws once you've got the drive installed. The enclosure looks good and keeps the drive relatively cool - it gets warm, but never hot to the touch (even after hours of use).UPDATE: using with a Thunderbolt dock. I tried using this enclosure with several Wavlink Thunderbolt docks, and with each of them the drive only performed in USB 3.2 mode, achieving reads/writes of around 1GBps - much slower than if connected to the Mac directly. After some research, it transpires people using this enclosure with other docks (CalDigit TS4, mainly) were having the same issues. Talking to OWC's tech support over email (they responded quickly), I asked if their docks would enable the enclosure/drive to perform at USB 4 speeds. They said yes, so I bought the OWC 11-port Thunderbolt 4 dock and it worked. You won't get quite full performance when using a dock, but I am getting over 2GBps reads and writes (almost 3GBps reads) via the OWC dock and am happy with that. So if you are intending to use this drive with a dock, or wondering why it doesn't perform optimally with the one you're using, my recommendation is to (unfortunately) shell out for an OWC one. ### ⭐⭐⭐⭐⭐ Is there any better enclosure at these speeds? *by on Reviewed in the United Kingdom 30 December 2025* Not sure you can do better than this enclosure at this price.It’s fanless, so it’s entirely silent during operation and you don’t have to worry about the fan failing, which is huge double bonus. This should literally last as long as the components inside it do, with no other point of failure. Built with maximum efficiency so it stays at safe temps even during prolonged use.It’s rock solid, build like a brick, feels premium and high quality and has never gotten too hot to touch, only very warm when in use. It is a heat sink so it gets warm even when idle but that’s expected. It fell off my shelf (about 8 inch drop onto hardwood floor) with ssd installed and no affect on performance, not even a scuff!Every other enclosure I researched either had a fan (noise, point of failure) or had sketchy prolonged temps. This is the only one I found that does everything you could want an enclosure to do. It’s rare to find a product that has no discernible con or trade off, but this might just be it!Paired with a 990 Pro on MBP for gaming and works like a charm. It’s half the speed of the 990 Pro so will look at getting a faster enclosure in the future to unlock max SSD speeds. Until then this does everything it needs to. ### ⭐⭐⭐⭐⭐ Great external drive for M3 Macbook Pro when combined with Crucial P510 SSD *by on Reviewed in the United Kingdom 29 March 2026* Easy install with 2TB Crucial P510 2280 M.2 SSD.M3 Macbook Pro Thunderbird port - Sequoia Black Magic Disk Speed Test: Write 3127 MB/s Read 3074 MB/s.Good speed results with SupeDuper! backup of Mac HD and SD card imaging.Heat sink runs warm to the touch - doing its's job, that's what it's for!Easy to setup APFS volumes in macOS Disk Utility with min & max size limits.Eay to add as second backup drive for TimeMachine - will see how that goes ... ## Frequently Bought Together - OWC Express 1M2 Portable NVMe Thunderbolt (USB-C) SSD USB4 Ultra Fast External SSD Drive with Aluminum Heat Sink Enclosure (Enclosure Only) - Samsung 990 PRO SSD 4TB PCIe 4.0 M.2 2280 Internal Solid State Hard Drive, Seq.
