After-market SSDs which support SATA bus speed of 3.0 Gb/s will operate at that bus speed. Depending on the data transfer test method used, your actual data throughput from a 3.0 Gb/s SATA bus speed should be 220-250 MB/s and about 90-120MB/s throughput when running on SATA bus of 1.5 Gb/s. This is due to the bus signaling used for the SATA bus, as well as overhead for error checking.

Upravo ono o čemu sam ja govorio, znači sabirnica sa SATA-I specifikacijom će raditi na 1.5 Gb/s, odnosno 192 MB/s, a ne 150 MB/s kak sam govorio, ali zbog ostale "signalizacije" i error checking-a će biti prijenos od maksimalno 120 MB/s korisnih podataka
