WebDAV is also an object storage protocol but it can do random access. Well, almost. Partial reads are supported everywhere out of box just by using the Content-Range HTTP header. Partial writes aren't standard, but some implementations e.g. SabreDAV can do those using PATCH with X-Update-Range header (and e.g. rclone supports this). WebDAV has its warts and limitations but it's a very underappreciated protocol.
