Silicon Power XD80 M.2 2280 2TB PCIe 3.0 SSD Review

Storage/SSD by stefan @ 2022-09-25

The new XD80 2TB version from Silicon Power is very interesting, since it does not come with the previous controller but retains the same internal product code. As we have noted from the test results, the drive trades punches in terms of performance with the 1TB version while blank, but when filled to about 60% of its capacity, it falls a bit behind. We think that this can be attributed to the Realtek RTS5762 controller, which operates differently but unfortunately not a lot of info is available online about it.

Drive Behavior during Continuous Write

Our continuous tests began while the drive was at 40 degrees Celsius:

The write speeds have started optimally:

At the same time, the drive temperature started raising a little:

After more than 83GB of written data, we haven’t noticed slowdowns:

At this moment in time, the temperature has raised to about 50 degrees Celsius:

The transfer speeds remained between 1.85GB/s and 2.01GB/s after writing about 170GB of data:

After writing about 272GB of data, same situation remained:

The temperature did raise to about 63 degrees Celsius:

The first notable slowdown has occurred after writing 441GB of data, when the speed dropped to about 1.68GB/s:

At this time, the controller has reached about 68 degrees Celsius:

The speed remained good even after writing about 537GB of data:

The temperature has raised to about 74 degrees at this stage:

We have noted another drop in performance, to about 960MB/s, after writing over 600GB of data; this behavior is expected after SLC buffer has been filled up:

The temperature remained at about 73 degrees Celsius:

After writing some more data, we noted yet another speed drop, to about 488MB/s:

For the rest of the test, the speed did travel between 148MB/s and 210MB/s:
