My hdd is failing and I am thinking of replacing it.


Now my old HDD is Seagate Barracuda 1tb 7200RPM 3.0gb/s SATA 32MB cache 3.5" desktop.


I decided to stick to same brand - Seagate so right now I am looking at 2 choices.



Seagate Barracuda ST1000DM003 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive Bare Drive




Seagate Hybrid Drive ST1000DX001 1TB MLC/8GB 64MB Cache SATA 6.0Gb/s NCQ 3.5" Desktop SSHD


My question is two fold:

1)  Will both these drive be compatible to replace my old 3.0GB/s 32MB cache drive (without any extra modifications/materials)?


2) Will any of these drives make ANY difference in the speed and performance of my 4+ yr desktop PC or they just perform up to capacity of my old (3.0gb/s, 32mb cache) drive and no more?

The biggest difference will be in a shorter boot time using the hybrid drive. The SSD part will cache the files used during boot.

I don't know of any reason why both would not be compatible with your computer.


If you want some real techie info on the hydrid drive and comparisons there are several pages in the below link. The link is not

to the first page but a comparison speed page.
