The article seems slightly pedantic in the argument that Mass Storage is "SCSI"—it implements a subset of the protocol, so yes, it has some bits of SCSI, but I don't think it follows to say "USB Mass Storage is SCSI".
- trasz 6y agoEvery SCSI device implements a subset. The difference is the transport; higher layers of the SCSI stack, like the part that handles SCSI disks (as opposed to eg optical drives), don’t really care. They talk SCSI. As a sidenote, if you configure FreeBSD on Raspberry Pi 0 to serve USB Mass Storage (like the gadget functionality in Linux), the USB-tunneled SCSI requests will be handled by the same target that serves Fibre Channel or iSCSI, with persistent reservations, VAAI and other features that might feel like a bit of an overkill for a virtual flash drive.
