Seems to have conflicting info? Second paragraph: Thunderbolt Share offers several options, all at blazing 40Gbps or higher speeds ... Yet further down the page it has: Thunderbolt Share uses up to a 20Gbps connection over Thunderbolt 4 ... And even further down the page it has this: Drag and drop files: Nothing special, though the copy/move functions should take place at Thunderbolt speeds — between 80Gbps and 120Gbps speeds, depending on the specification.

> Nothing special, though the copy/move functions should take place at Thunderbolt speeds — between 80Gbps and 120Gbps speeds, depending on the specification. 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.

  For 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.

  In 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. ;)
