A Fully In House Solution
The new SK Hynix Platinum P41 2TB SSD is a bit more interesting than some other PCIe 4.0 NVMe drives as it is using a completely new controller, not to mention the benefit that the flash and RAM are both make by SK Hynix as well. Their new Aries ACNS075 controller has eight channels and supports NVMe version 1.4, the flash is their new 176-layer 3D TLC and the 2GB cache is a single Hynix LPDDR4-4266 chip.
Trying out the Platinum P41 will cost you a bit, the 500GB is $105, the 1TB is $150, and the 2TB tested in this review runs you $260, though you should have them for a while as endurance is rated at 500 TBW, 750 TBW, and 1200 TBW respectively and you get a five year warranty as well.
There are a few tests the Platinum P41 struggles with, offering middling performance in WinRAR extraction and decrypting for a Steam installation, however in the the overwhelming majority of tests the P41 is either best or top three. Considering the competition it is against that showing is utterly brilliant. This is pretty much the best drive out there right now; the problem is you have to pay a pretty premium to be able to beat the competition by a tiny percentage.
