SATA backwards compatability

[questorran]

Hello,
Do the SATA 3.0 hard drives work on the SATA 1.0 connections?

Another way to ask the question...What are the odds that a new hard drive will connect in my 5 year old computer?

The SATA 3 hard drive would work, it would simply be restricted to the SATA 1 speeds.

Worst case, you may need to apply a jumper to force the drive to sata1 speeds. Some older disk controllers don't negotiate the transfer speed the way they are supposed to.
