I am looking to make a really large home built file server. I am aware that there are NAS solutions that will let me put maybe a dozen hard drives in them that are available fairly inexpensively, but I need more like 50 - 100 drives, each in the 10-20 terabyte range. Absolute top performance would be nice, but network speed is going to be the limiting factor anyway. My thought is if the new USB standards like USB4 will still allow you to connect a whole lot of devices, and if there are reasonably priced adapters available, then I could hook up a rack of drives this way. Does anyone know how many devices you can hook up to USB4 and if USB to hard drive (as opposed to the easy to find USB to NVME) adapters are available? Thank you.
