Silicon Power US75 2TB, M.2 2280 / M-Key / PCIe 4.0 x4

DRAM-less SSDs have always been considered to be inferior to DRAM models due to their less than remarkable performance and well that does hold true not just for the US75 but also many others based on NAND controllers like the MaXio MAP1602. The thing however is that from synthetic benchmarks to real world performance things change a lot and so for most consumers out there it will not really matter if they have a DRAM or a DRAM-less SSD installed in their systems. Now it’s clear from the charts that the US75 exchanges blows with the FX700 model by HP and well, that’s good especially when you take into account that other models with the same NAND flash controller produce much worse numbers. By using YMTC's 232-layer 3D TLC NAND Silicon Power also reports much higher TBW numbers compared to all the others using their new 232-layer 3D QLC NAND and well, this should make a huge difference to most consumers and even professionals out there.

The US75 2TB drive from Silicon Power does use less familiar components, such as the MAXIO MAP1602A 4-channel controller but also the YMTC VSYMT04TA104 232-layer NAND with Xtacking 3.0 technology; this new technology incorporates a 6-plane NAND design which does improve speed and also efficiency. We were quite surprised that the drive can maintain up to 850MB/s writes even after having filled more than half of the capacity, while the drive price is good when compared to the competition.
