2TB Barracuda LP
At idle, the 2TB Barracuda LP produced very little noise, and its character was very smooth, with only a soft 'whoosh' escaping from its casing.
The sharp ticks that typically accompany seek activity were also well-subdued.

Our analysis shows a low frequency peak at just under 100Hz in idle, which is as it should be (5900rpm = 98.3 Hz).
The slightly higher peak during seek is the result of some extraneous low frequency artifact from outside the chamber, as our anechoic chamber is not very sound proof below ~150 Hz.
1TB Pipeline HD .2
The 1TB Pipeline HD .2, being a 2-platter model idled at only 12 dBA@1m, matching
the 500GB Samsung EcoGreen. The noise character was mostly smooth with a bit
of metallic twinge which was only noticeable close up. During seek, the drive
measured 16 dBA seeking was soft with only slight audible chatter.

500GB Pipeline HD .2
The 1-platter 500GB Pipeline HD .2 was the best of the bunch, delivering some
of the best acoustic results ever. It measured 13 dBA@1m when idle
(only 2 dBA above our noise floor) and just about half a dB higher when seeking.
The overall noise character was similar to the other two drives.
