That seems a bit fantastical. There are no hard drives I'm aware of that will permit sustained I/O at those speeds, in fact I'm pretty sure NVMe doesn't have the bandwidth for this.
Unless you hook up a drive with RAM characteristics to PCIe 6.0 x8+ I don't see this happening anytime soon.
- vardump 2y agoFor example Crucial T705 [0] can do 14.1 GB/s sequential reads. That's 113 Gbps. Requires PCIe5, though. A lot of "old" NVMe disks can also do over 50 Gbps. Samsung 980/990, WD SN850X come to mind right away. You could run two in a RAID-0 configuration to get over 100 Gbps.

- justinclift 2y agoIn the business/enterprise space, local arrays of flash drives can push those kinds of speeds in a sustained fashion. For example: https://www.highpoint-tech.com/nvme-individual/ssd7749e https://www.highpoint-tech.com/nvme-individual/ssd7749e (that card can theoretically go quite a bit faster) But yeah, seems like a bit of a stretch to be portraying it as consumer stuff. Maybe give it a few years though, cat pictures aren't losing resolution. ;)
