HD TACH RESULTS


HD Tach results for our 1TB Pipeline HD .2. The other drives performed similarly.

All three Seagates performed similarly in HD Tach. Like most quiet drives, random access time was higher than usual, but the 2TB and 1TB models managed to edge out the competition in this regard by 2-3ms, while the 500GB Pipeline was 1-2ms slower. Average read speeds were excellent though, with all three drives measuring about 95MB/s, on par with 7200rpm models.

AUDIO RECORDINGS

These recordings were made with a high resolution, lab quality, digital recording system inside SPCR's own 11 dBA ambient anechoic chamber, then converted to LAME 128kbps encoded MP3s. We've listened long and hard to ensure there is no audible degradation from the original WAV files to these MP3s. They represent a quick snapshot of what we heard during the review.

These recordings are intended to give you an idea of how the product sounds in actual use — one meter is a reasonable typical distance between a computer or computer component and your ear. The recording contains stretches of ambient noise that you can use to judge the relative loudness of the subject. Be aware that very quiet subjects may not be audible — if we couldn't hear it from one meter, chances are we couldn't record it either!

The recording starts with 5 to 10 seconds of ambient noise, then 10 second segments of the drive in the following states: idle, seek with AAM enabled (if applicable), and seek with AAM disabled (if applicable).
