HD TACH RESULTS
HD Tach results for Samsung HD502HI. |
The HD502HI provided good performance in HD Tach. Random access time averaged 16~17ms over several repeated tests, and average
read speed was
87 MB/s. This is a slight edge over other recently reviewed 5400rpm drives, but probably difficult to notice as improved speed in actual use. It fares well against 7200rpm drives of similar capacity. Random access is a bit slower but read speed is very close. (Consider that the best read we've measured on a 7200rpm desktop drives is 107mb/s for the Seagate 7200.11 1.5TB.)
