PCIe gen 5 speeds are double PCIe gen 4 speeds, for the same number of lanes of course. Whether a hard drive is capable of those speeds is another story (although my current drive pushes the limits of gen 4). I’m not sure what the fastest PCIe gen 5 hard drive on the market is right now, but eventually we will start to approach the limits of gen 5 and start looking at gen 6 drives, at least at this rate.
