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: Good SSD enclosure - 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.

## Questions & Answers

**Q: Why does the read and write speed drop below 1000Mb/S**
A: When the tested read speed of the drive is 2600–2800MB/s (close to the interface bandwidth limit). Write speed is drive-limited, affected by its controller chip, cache size and flash memory type.

**Q: Does this NVMe enclosure overheat during 4K video editing?**
A: The enclosure has a built-in switchable cooling fan and an aluminium housing, which helps keep the SSD at a stable temperature during heavy tasks like 4K video editing or large file transfers.

**Q: On Windows systems, the read speed ranges from 1800–3000MB/s, while the write speed only reaches a few**
A: On Windows (with Thunderbolt driver installed) Disk Management → Right-click drive → Properties → Policies → Enable Better Performance (Read) → Confirm and test read speed.
