super speed as stated! speed, reliability, warranty, brand mute  Oleksandr Mitel: use WD WDS100T4X0E few months |
Maybe someone is interested in how it performs on PCI-E 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  Vitaliy: use WD WDS200T4X0E less than month |
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. vlursu: use WD WDS200T4X0E less than month |
