The purchase was made based on my personal needs. I wanted the smallest size, with a metal casing, and the USB plug to have a removable cap. I also got as a gift the dual USB A + C connection.

During the tests/measurements that lasted over 1 hour, with room temperature at 20 degrees Celsius, the product had a lukewarm temperature on its casing. The following measurements are minimal compared to the ones I did myself.
The tests were done with the Total Commander 11.50 application.
1. write - file copy from M2
It starts from the first 1GB and writes at 648MB, and by the time it reaches 17GB of transfer, the write speed increases to 718MB. At 48GB, the write speed drops to 314MB and remains stable until the end.
2. read - file copy from USB stick
The entire transfer is stable at 1022MB.
As shown by the measurements, the company does not have consistent use of flash memory in its production. In an old review I read, it has pSLC-Cache at 73GB. After that, the write speed drops to 90MB. The product I have in my hands has pSLC-Cache at 48GB and then the write speed drops to 314MB. With HD Tune I confirm the cache. I consider the recent production model better.

The product is recognized in Windows 11 as HD SCSI. The default format option is NTFS. For those who want, there is also the option for exFAT.
---
Without any problem, it was also tested as a boot USB disk using Rufus to install Kaspersky Rescue Disk 18. The PC booted without issue from the USB stick into the Linux OS.
---
As an HD recognized by the OS, we can use applications like hwinfo to see information such as health, data transfer volume, etc.

The two caps have a moderate feel when snapping on. The only strange thing is that they have a top and bottom. If snapped on upside down, the plastic is not aligned with the metal casing
