Some of you may have seen me post about drive wattages, here's a bunch of info that I've just been compiling. Since I was looking I figured I'd copy it and make it available for everyone as it wasn't always easy to find every bit of info.
I've tried to list the series, speed, buffer, and warranty in the notes since those are other important factors. All are SATA versions - some lines had SAS or IDE - but I figured this was aimed mostly at WHS users. I've also included non-LP/GP and enterprise-class drives at the end of each manufacturer's listing under 'Select drives for comparison'.
Let me know if you find any errors. If this seems useful to everyone else I'll end up maintaining it.
Western Digital
Seagate
Samsung
Note: Samsung OEM drives carry 30 day warranty.
Hitachi
Hitachi had the most masked information hidden in white papers. Their drives use a "normal idle", "unload idle", and "low idle" which you can read about here. Unfortunately they don't seem to give read/write power specs anywhere. I've also noted the Deskstar drives as 7200rpm but it is unclear if and how much the drives spin down in their various modes.

Notes:
W/TB = watts per terabyte using idle wattage
MB/s figures are taken from Storagereview.com's Benchmark database: "Maximum Transfer Rate (Read). The sequential transfer rate attained by the outermost zones in the hard disk. The figure typically represents the highest sustained transfer rate a drive delivers" in white; and Tomshardware.com's "h2benchw 3.12: Max Read Throughput Read Transfer Rates ([MB/s, sorted by average])" in cyan. (If you know of a more complete database please let me know.)

Hitachi had the most masked information hidden in white papers. Their drives use a "normal idle", "unload idle", and "low idle" which you can read about here. Unfortunately they don't seem to give read/write power specs anywhere. I've also noted the Deskstar drives as 7200rpm but it is unclear if and how much the drives spin down in their various modes.

Notes:
W/TB = watts per terabyte using idle wattage
MB/s figures are taken from Storagereview.com's Benchmark database: "Maximum Transfer Rate (Read). The sequential transfer rate attained by the outermost zones in the hard disk. The figure typically represents the highest sustained transfer rate a drive delivers" in white; and Tomshardware.com's "h2benchw 3.12: Max Read Throughput Read Transfer Rates ([MB/s, sorted by average])" in cyan. (If you know of a more complete database please let me know.)
