Review: Great SSD quality enclosure - Very effective and high quality ssd enclosure. it is very well made, easy to set up with whatever SSD you have. It has a metal body and ventilation ports with the addition of a quiet switchable fan: so temperature control should not prove a problem. It is future proof in spec and although not cheap I feel offers very good long term use at a reasonable cost.
Review: Rock stable and fast! - Excellent enclosure - easy assembly, speed is excellent - around 3100MB/2900MB R/W.

### ⭐⭐⭐⭐ Good SSD enclosure
*by A***R on 5 September 2025*

This is a great external drive housing for a Mac Mini. Its Thunderbolt 4 connector means that it performs really well. Not quite as fast as the internal SSD but pretty close. It comes with a Thunderbolt 4 cable which is well constructed. Fitting the SSD was simple and took a few seconds. The case is metal and solid - it will survive the rigours of travel. My only criticism is that the fan needs to be switched on or off using a button. I would much rather that the fan is triggered when the SSD temperature goes above a certain level. I found the fan to be a little noisy but it is not far from me and it may be less intrusive in other setups.
