 The usable data rate of a Blu-ray Disc drive can be limited by the capacity of the drive's data interface.With a USB 2.0 interface, the maximum exploitable drive speed is 288 Mbit/s or 36 MB/s (also called 8× speed).A USB 3.0 interface (with proper cabling) does not have this limitation, nor do even the oldest version of Serial ATA (SATA, 150 MB/s) nor the latest Parallel ATA (133 MB/s) standards.
