...To znači da ćemo gotovo sigurno povećanjem kapaciteta ploča imati i sve veći random access time, nažalost.

Da takav se dojam (nazalost) ulavnom dobije, uzevsi u obzir novije HDD-ove veceg kapaciteta.
E sad, da li je to namjerno ucinjeno od strane proizvodjaca (ili je samo nuspojava vece gustoce zapisa), ne bi znao... premda neki potvrdjuju ono prvo:

Iz Western Digitala (Anandtech):
"After a lengthy conversation with Western Digital, we now understand why the drive performed so poorly in this test. This also explains the good but not great application results in general. Granted, the drive still performs well, but the initial specifications lead us to believe that performance should have been greatly improved over previous generation drives. Western Digital explained the single platter 320GB drive is aimed at the entry-level market where thermals and acoustics are critical for mass acceptance of the drive by the OEM and retail customers.

WD sacrificed a small amount of performance on the 320GB drive to meet these goals. This was by design and is not an indication of the performance potential of their new technology. In fact, these same 320GB platters will be used in single-sided form eventually for the 160GB drives. According to statistics, the 160GB drives have quickly replaced the 80GB products to become the new "sweet spot" in the general market. As the capacities increase, the typical user for these products normally expects a balance between performance, thermals, and acoustics. With that in mind, WD tuned the 640GB drive for additional performance at the expense of acoustics."
