Indeed. That would be a limitation on the USB driver stack though. Technically speaking, USB’s spec theoretically allows up to 256 serially addressed devices per root hub. You are going to saturate the USB bus with protocol traffic long before you reach that though. (the speed of the port is going to be a serious limiting factor in putting lots of storage on the device, at least as far as reliability is concerned.)
jharris1993: The issue with XP wrapping its filesystem was due to LBA. When it shipped, XP only supported 28bit LBA. There were disks that needed 48bit LBA to address the full drive. The lba register would overflow in the windows driver when trying to access these disks, unless you set a registry hack, and installed an updated atapi.sys. (Needs SP1 installed) In addition, there is a limit imposed by the old partition scheme, MBR-- which could only use 32bit LBAs. This limits the size of a disk to 2TB. (or 137GB, with the atapi issue.)
The Mycloud NAS uses linux internally. (Gen2 is still technically linux, even though it is a weaksauce busybox shrinkwrap embedded version) Linux knows all about GPT, the new partitioning schema, and has known about 48bit LBA for over a decade. There is not a reasonable technological reason why the Mycloud would be unable to see even a truly enormous sata disk attached to it.
