- A friend of mine recently picked up a 170M Western Digital Caviar 2170 hard
- drive (which seems to be a fairly new model). Testing its speed with
- Norton SI (assuming it produces realistic figures), the average access time
- is indeed very small (11ms as advertised) but the data transfer speed is only
- ~470K/s, as opposed to ~980K/s for a Seagate ST3144a (15ms access), when tested
- in the same system as a single drive. Even an old Seagate 40M MFM drive seems
- to have a higher data transfer speed.
-
- The data transfer figure is not commonly advertised, the access time is.
- Does the WD just have a low transfer speed (compensated for many purposes by
- its small access time), or is there something wrong here?
