 Feb 18 awarded Popular Question May 24 awarded Student May 24 comment What does “random seek time” really means in HDD benchmarks? Also, in a sweep (continuous blocks), let's say 120 blocks are all continuous, can I say there are still 120 random seeks inside when reading and it is just this kind of random seek is nearly nothing? May 24 comment What does “random seek time” really means in HDD benchmarks? If HW32 gives `random seek time = 20`, how should I understand it. Is that average or peak? for example, it can be that there are 120 blocks seeking seriously, so average is 20ms. It also can be only one serious random seek and then 120 blocks are continuous, then HW32 just record the peak. Otherwise, the value should be much lower in the 2nd case. is it? May 24 comment What does “random seek time” really means in HDD benchmarks? if a random read invovles 120 blocks, then there will be 120 random seek time, right? so a naive calculation is that a 120 block of read will have 120 * 20 ms = 2.4 sec random seek time, right? May 24 comment What does “random seek time” really means in HDD benchmarks? so you mean random seek time I get is a peak time, not the average? May 24 comment What does “random seek time” really means in HDD benchmarks? if it is usual, then how can random read be so quick, 30MBytes/s?
