Review: Transformed my 2019 27-inch iMac from painfully slow to lightning fast - My 2019 5K iMac had been crawling along on its original failing 2 TB Fusion Drive. 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: Works with ipad Pro get the version with the fan - This is a USB4 Thunderbolt 3 case. Fast. Works great. I have 3. It is a little pricey at $99us. But thunderbolt cases are much more expensive than standard USB3.2 cases. I have 2 with the intergraded fan and one without the fan. My drives run so much cooler with the fan. For longevity of your drives I recommend the version with the fan. Just make sure you don't block the intake to the fan. Hooks up to my M2 iPad Pro perfectly. Fan is very quite I can barely hear it.

### ⭐⭐⭐⭐⭐ Runs Fast and Cool from Mac mini M4
*by D***D on December 17, 2024*

Very happy with this silent fan Thunderbolt enclosure from Acasis. Installation of WD Black SN770 2tb M.2 2280 NVMe was quick & easy and Blackmagic app showed sustained 2680 writes/2860 reads using included thunderbolt cable when attached to my Mac mini M4. These speeds are faster than internal drive in my Mac mini M4. Temp was acceptable with thermal pads provided with enclosure however I did add "icepc M.2 2280 SSD Pure Copper Heatsink Kit Cooler" and iStat menu app showed @ 10 degrees cooler temps compared with the thermal pads only. Probably cause the copper/thermal pad combo now has a very tight fit and contacts enclosure lid. Push button on enclosure allows fan to be turned on/off - but I leave it on (pushed in). Fan is very quiet and makes a big difference in cooling than with it off.
