OWC Accelsior 8M2 is a PCIe 4.0 x16 SSD with up to 64TB capacity and 26,000MB/s speed
See that graphics card? Actually, it is not a GPU at all! While it does have a x16 PCIe connector, it is a solid state drive -- sort of. Actually, it technically is not a drive itself, but instead, a card that you plug SSDs into. Called "Accelsior 8M2," it can be had with up to 64TB of storage pre-installed with an insane performance of up to 26,000MB/s.
Yeah, the actively cooled OWC Accelsior 8M2 is an absolute beast. In fact, the company claims it is the "world’s fastest and highest capacity PCIe SSD." With that said, you will need a pretty modern computer to truly take advantage of the high-end performance. You see, a desktop with a PCIe 4.0 x16 slot will be necessary to achieve the promised top speeds. It will be compatible with previous generation PCIe x16 slots, just not at full speed.
