Review on PALMEXX Enclosure for M.2 M-key NVMe SATA SSD in USB/USBC 3.0 6Gbps by Stanislaw Lambach ᠌

With its pros: Nice one piece body. The caps covering the connectors are made in the corresponding style and the same color - they are not striking, like some other similar devices, The massive metal case does a very good job of dissipating heat from the disk, provided that thermal pads are used (they are not included in the kit!): a good thermal pad (I used with a conductivity of 13W / mK) the disk does not heat up over 47 degrees in CrystalDiskMark when performing a random file write in 4Kb segments in multithreading mode (RND4K Q32T1). Tested on KINGSTON-SA2022M81000G and Samsung-SSD-980-500GB on USB 3.2 Gen 2 interface. Some cons: There are no thermal pads included. Without them, the disk heats up to 70 degrees in CrystalDiskMark when randomly writing a file in 4Kb segments in multithreading mode (RND4K Q32T1) to a USB 3.2 Gen 2 interface in 2-3 minutes, after which it slows down. It is inconvenient to use thermal pads with this case, since it is monolithic and the disk slides into it along with the board. Accordingly, you will have to try to push it so that the thermal pad provides tight contact between the disk and the case and at the same time allows you to assemble the device. With the KINGSTON-SA2022M81000G disk, I used a 2mm thermal pad - the result is described in the merits. Of the other shortcomings - the device is quite large, there are smaller analogues (but they cope worse with cooling). The caps are not attached to anything; consequently, they are easy to lose.
