Bandwidth figures are PCIe 6.0 link limits, not measured card performance.
Our first PCIe Gen6 card is in prototype. PCIe 6.0 runs each lane at 64 GT/s, twice the 32 GT/s of Gen5, so an x16 link can move up to 128 GB/s in each direction, or 256 GB/s with both directions combined. Drive count, capacity and form factor will be announced once the prototypes finish testing.
Each PCIe generation doubles the data rate per lane. Theoretical x16 link bandwidth in each direction:
Gen4 x16: 16 GT/s per lane, about 32 GB/s
Gen5 x16: 32 GT/s per lane, about 64 GB/s
Gen6 x16: 64 GT/s per lane, about 128 GB/s
These are link limits, not card measurements. Real throughput depends on the drives and the host. We will publish measured figures after testing, as we did for the X16 Gen5 and X28 Gen5.
