... transfer rate (STR) of HDDs This performance graph questions the need to change to meet the bandwidth requirements of a new wave of desktop class (5400-RPM and 7200-RPM) HDDs. TTL signals define an 8-bit digital value, through 9 of command signals. It would be very difficult to increase the speed of ATA beyond ATA 133. Serial ATA technology Serial ATA discards the parallel ATA Master/Slave concept and only allows one drive at a time...

As a result, serial signaling rates can occur at a much greater speed than in multiple parallel streams. SATA incorporates an low voltage differential (LVD) signaling scheme that uses two pairs of electrical noise. The 8b/10b encoder converts each pair (Figure 3). Low voltage differential signaling SATA technology transmits signals in a single stream rather than in parallel ATA. The data is represented by...
