Quality to be reviewed
After a few years (only used occasionally), some of the LEDs no longer work, and the case gets very hot.
(Since the beginning, paste and heat sink in place).
As a result, during long copies, the SSD adapts its speed and reduces it according to the temperature.
This doesn't come from the M2 SSD, but from the LEDs, because in a cross-test, the same SDD in another case from the same brand (ICY BOX IB-1817MC-C31) was barely warm, and the speeds were top-notch.
Avoid this product.
