The chart they display is for idle noise; they don't have any discussion about seek noise except when they say "when it is not being accessed, then you practically cannot hear it"
, which makes me think that it does make some noticable seek noise. As to how loud that seek noise is, I don't know. Of course, seek noise can sometimes be adjusted by setting the drives acoustic settings using a utility like the one from IBM
, so maybe the Samsung can be made very quiet. But THG doesn't say enough about seek noise to know.
It's also important to remember that one of the things that contributes to the perceived quietness of the Barracuda IVs is that they don't sound very different between idle and seek. A constant low noise level is much less distracting than near silence punctuated by the woodpecker-on-speed sound of noisy seeks.
