As title really, looking to upgrade from 2 320gb Seagate 7200.10's, and trying to get the most efficient drive I can without spending more than I need to. :)
 
Thanks for the replies, but it's only a 5400rpm drive, and not a 7200rpm. TBH, I probably wouldn't notice the difference, but I'm currently using a 7200rpm drive, and didn't really want to 'downgrade' that speed.
Don't dismiss the WD Green Power. It may only be 5400rpm, but it's probably quite a bit faster than your existing drives. I have one of the 640GB GPs and I'm very impressed with its performance. And it is absolutely the quietest, most cool running drive out there atm.

Its 5400rpm - 7200rpm, It all depends whats its doing as what speed it runs at.

Thats the speed of the WD Green Power 8mb cache drive,, it should have been the 16mb cache drive

No. That was a silly idea that sprung up because WD wouldn't admit what the GP's spin speed is. The guys at one hardware site (SPCR I think) analysed the GP's motor noise and the trace confirms the drive spins at 5400rpm all the time.

My 640GB GP:

 
So the access time on a 16mb cache GP drive would be much lower then 20ms, if I got my money back on the 8mb version?

no its not dont get fussed over 8mb vs 16mb cache, like i explained to you over msn, main use of cache on a hard drive comes from supplying burst data across the interface. and do take into account that with more cache if your drive is set to use command queuing more cache can store more commands. in the end cache hardly makes a large impact on drive speed. it mainly boils down to drive rotation speed and platter density.

and as i explained to you over msn you 20ms speed is crap possibly because you are using AAM and you need to disable it to get the drive into performance mode.
 
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.
