I rebuilt most of my system last year, new MB, CPU and RAM, carrying over a lot of other hardware, including my trusty old Samsung 300 GB drives.
The way I am currently set up is that I have one drive partitioned with my system partition and a second program partition, the second drive is a general storage dump. Now, unsurprisingly, my program partition (201 GB) is nearly full so I'm looking at a new drive.
I am considering some pretty well priced drives, but they are 'eco' drives. Western Digital Caviar Greens, or alternately Samsun Eco Green drives.
Now I know these use features to make them more power efficient, but will I see a performance compromise going from these drives from my old drives? Or are the newer ones likely to be better? Or will it make little difference? My drives are the weak link in the Windows Performance Index, I realise that's not a great benchmark, but a handy indicator.
I have 4 gigs of RAM, so I'm not sure how much Windows 7 benefits from using that to cache.
