Most power efficient 1TB 7200rpm drive?

I got two WD10EAVS yesterday when I wanted WD10EACS. They chart just like you drives, faster than my four platter WD10EACS but with a 20ms access time.

As Cyber-Mav says, the access time is high because these drives are meant for PVR's and need to be quiet Simply adjust the AAM to peformance and enjoy the 14.5ms access time that follows. (i've benched this using HD Tune, it drops over 5ms)

My biggest concern is the warranty but I cba to send them back.

Im guessing youve read my other thread about the EAVS has only 8mb cache and no warrenty but the EACS has 16mb cache and 3yr warrant?. I had sent mine bace 3 times but kept getting the same model back again, so In the end I got a refund and ordered it from somewhere else, and now I have the right model, the EACS.

Ive tried to disable the AAM but it wont disable for some reason, and dont want to mess with it too much to force it to disable, cos theres too much data on the drive to loose
 
Oh yeah, the reason why the EACS isnt listest on the WD site any where is cos the drives are not made for the public and only for system builders, like dell, Toshiba ect, and thats why you dont get a warranty.
 
Yeah the EAVS model is slightly faster then the EACS

I have two of them now, both disabled AAM via Hitatchi Feature Tool (http://www.hitachigst.com/hdd/support/download.htm)

You need to set it to maximum performance(253/254), not disabled with the WD10EAVS. With the WD10EACS disabled is actually disabled, this seems not to be the case with the WD10EAVS, disabled actually puts it into quiet mode.

However with AAM at max performance it performs just like the WD10EACS.

I'm running RAID 5 so the cache is irrelevant, the WD10EAVS is always a 3 platter drive which is faster than a 4 platter WD10EACS (unless you get lucky and get a 3 platter WD10EACS)

The warranty bothers me but bought from a very reputable long time retailer and I can afford to buy a new drive if needs be. I have four in RAID 5 and if one goes after a year its not the end of the world. If one fails in my array I wouldn't wait for an RMA anyway, it would take too long.

Surely not a RAID5 user that doesn't have a hot spare, you must at least have cold spare? RAID5 is all about 'uptime' isn't it?
 
Can't seem to drop the access time on my WD10EAVS by playing with the AAM settings using the Hitachi HD Tune tool.

Have tried disabled, enabled and also the custom enabled, which only seems to allow settings of 128 & 254 when accepted. All give 20msec access time.
