It may not look like much, but the Addlink S90 is a tiny revolutionary. A small drive trying to upset the status quo. Conventional wisdom says quality storage only comes from a few big players. Names like Samsung, Western Digital, Crucial, Intel et al. Addlink doesn't have much respect for the old ways though, so following the success of its S70 (which makes a prominent appearance in our best NVMe SSD guide), the S90 moves things up a level by offering speedy PCIe 4.0 throughput. Which isn't bad for a company predominantly seen as a budget player.
If you've followed the shift to PCIe 4.0 at all, you'll have spotted that every drive out there currently uses the Phison E16 controller, whether that's the Corsair Force MP600, Gigabyte Aorus SSD, or Seagate FireCuda 520. And sure enough that's what you'll find underneath the sticker here, alongside the equally ubiquitous Toshiba 3D TLC NAND flash memory. They're not all exactly the same, but they're close enough to be almost indistinguishable.
