I already have the kit to do so and the cloning software, i was just wondering if i bought a sata 3.0gb/s hdd and if i had a 1.5, would the new hdd still work in my laptop?

If not, how do i check to see which kind i have?

Yes, I believe that SATA II is backwards compatible.

Heya,

First of all, SATA is what it is, the 1.5 and 3.0, or I and II respectively make no difference in terms of compatability. It's the same exact connection. There's no reason to have backwards compatability because it's the same. The difference is simply that one has more bandwidth potential than the other.

That said, your Laptop's controller may be the 1.5gbps SATA and so whatever you attach to it (be it 1.5 or 3.0gbps SATA) will throttle around that speed. So if you throw a SATA II 3.0gbps drive in there, it will work perfectly fine.

Also note, there is no single laptop hard drive (short of a brand new highly expensive SSD) that can actually fill the bandwidth of 1.5gbps. Let alone 3.0gbps. Find me a singlelaptop drive that can sustain 300 megs per second on a transfer and we'll worry about it. While you're at it, find a single laptop drive that can sustain 150 megs per second on a transfer (again, only a really good quality SSD would be able to get close to that in a single-drive form). Basically, you won't. So realistically, it won't matter what drive you throw in there.

So, whatever drive you buy, so long as it uses SATA connections, you'll be absolutely fine.

Very best,
