Interface Bandwidth And Access Time
This benchmark is used to verify the interface claims of drive manufacturers. Clearly, the Hitachi Travelstar 5K500 and 5K320 utilize Serial ATA 3 Gb/s, as they reach 160 MB/s. The Samsung Spinpoint M6 HM500LI stays at 127.7 MB/s.
The Samsung HM500LI is as bad in the access time test as it was good in the data transfer benchmarks: 19 ms is a new record on the low side. However, the two Hitachi drives aren’t all that great either, at 18 and 18.5 ms.
