wonderful model, really honored
6 November 2025 
Maybe someone is interested in how it performs on PCIe 3.0 with AMD. I added screenshots.
it's cool that there's only one chip for the 2TB version, it's a pretty hyped model, let's see how it really is
1.8TB available capacity, no radiator or mounting screw, it heats up normally

great model, love it

Fast reliable drive. In the 2TB version, only 1 memory chip. Thin board - element layout on one side of the drive.
Modern controller with good memory. High speeds and impressive operating lifespan. Moderate price for such parameters.
Noticeable heat when copying more than 80-100GB. It is recommended to additionally use a heatsink.
