I get 90 MB/s FTP speeds on me server.
PS3 ~30 MB/s.
Yeh, USB 3 is faster when it comes to transferring shit from a PC with USB 3 to a external device, but the PS3 is still limited to USB 2 speeds.
i get 130 - 140MBytes per second when transferring to my in house server or to a USB 3.0 hdd
i get 20Mbytes per second when transferring to my ps3
ill rather transferring to my external hdd
