Cold boot times were routinely 5–8 minutes, and even opening apps felt like 2010 all over again. I had heard success stories of opting for an external drive to replace the failing Fusion Drive and bought the ACASIS Thunderbolt 3 enclosure + Samsung 990 PRO 2 TB combo. Result: - Cold boot to login screen: 25 seconds - Fully usable desktop: 40 seconds - Parallels Desktop now runs Windows 11 + Debian Linux side-by-side with zero lag (impossible before) - Large file transfers are instant - Maintained 2 TB of storage Install was straightforward: cloned my drive, set the external as startup disk, and it just worked. The built-in fan is whisper-quiet but keeps the 990 PRO cool even under heavy load. Build quality is excellent – solid aluminum, short Thunderbolt cable included, and the little fan toggle is a nice touch. If you have an older Intel iMac that’s dragging its feet, this might be the single best upgrade you can make in 2025. Zero regrets – my six-year-old machine feels brand new again. Highly recommended! Review: Good so far, 3 internal temp sensors on 401 Pro - I put a Samsung 990P 2TB in my 401 Pro case. Everything was a breeze except that it took me a moment to read the instructions and put the little rubber grommet in to hold down the SSD drive; otherwise it wanted to angle up. Plugged it into my Mac, it said it was unreadable and offered to initialize it, which opened up Disk Utility. Not entirely obvious but it seems Erase is the command you choose to format a drive. That took less than a minute. After that MacOS volunteered to back my internal drive up to this via Time Machine, and I acquiesed quickly and set it to use no more than 1.25TB of the 2TB. I was pleased to see that the enclosure apparently has no less than 3 temperature sensors (again, this is the Pro version with fan, so I don't know about the normal version nor about previous Pro versions if any). They don't show up on most of my utilities, but they do show up on TG Pro. So far the drive has been running for an hour solid and the highest of the 3 cases temperatures (Top Case) is 44 C. The enclosure specs and the drive specs both say max 70 C, so I'm pretty happy with 44 C--in fact, the highest sensor on my internal drive is reading the same. I am wondering how long I can expect the drive to last. I won't be doing A/V work, but I will move my massive Photos library to the drive, in addition to Time Machine. I'm guessing maybe 5 years is a pretty safe bet? I expect SSD storage to drop further in price by then. BTW, I am assuming that if the enclosure dies I just move the SSD to a new enclosure. Of course, if the SSD dies, the data is gone, but that's why this drive is for backups, local copies, and other non-crucial things. ## Features - [Active Fan Cooling] 2026 Upgraded ACASIS 40gbps M.2 NVMe ssd enclosure built-in silent cooling fan; press the switch to activate the active cooling function.

I am a professional video editor and I transfer video footage all the time using external drives when I need to be on the go. I can use it with pretty much all my devices to get the optimum speed since I paired it with a 2tb SK Hynix P41. I can get crazy fast speed on my M2 Pro Mac Mini using Thunderbolt 4 then use it on my Ryzen 7950x PC with the Gigabyte X870E Aorus Elite with USB4. Being backwards compatible I can then use it on my Dell laptop with USB3 or the Thunderbolt 3 port which ever is not being used since it charges through the type c connector. The fan is pretty much inaudible over room tone and can only hear it when holding it up to my ear. I keeps my NVME drive in the optimal operating temperature even under high loads which i can say about my other enclosures where I experiences thermal throttling. I know it's expensive but it is worth it to have such flexibility. ## Frequently Bought Together - ACASIS 40Gbps M.2 NVMe SSD Enclosure with Cooling Fan, Tool Free Installation, TBU401 Pro for M1 M2 Pro/Max, Compatible with Thunderbolt3/4/5,USB4/3.2/3.1/3.0/2, Support 2280/2260/2242/2230 B+M M-Key - Samsung 990 PRO SSD NVMe M.2 PCIe Gen4, M.2 2280 Internal Solid State Hard Drive, Seq.
