The Addlink S90 Lite is a mid-range PCIe 4.0 NVMe SSD that offers nothing new but provides a satisfactory experience at 2TB without breaking the bank. It’s efficient and cool-running enough for laptop and PlayStation 5 use, and also would be a good way to add extra storage to your desktop. It’s very similar to the Corsair MP600 GS but is easier to find at 2TB and its price is competitive with other options. In some cases you could go cheaper with QLC or potentially pay more for the better-performing, TLC-based WD Black SN770. The S90 Lite is somewhere in-between, but nowhere near the performance or value of the best SSDs on the market.
Although unexceptional, the S90 Lite does have some quirks. At 2TB it has an overabundance of NAND flash dies which negatively impacts its performance, giving the Black SN770 an edge. It also has a different pSLC cache response than the MP600 GS which makes it a lot less useful for sustained workloads, although on the bright side that prevents the drive from overheating. Some drives in this class, like the Silicon Power UD90 and Team Group MP44L, have swapped to QLC at high capacity, and that’s also possible for the S90 Lite. Such a configuration would be more comparable to the Solidigm P41 Plus or Crucial P3 Plus, so beware.
