Can a SATA I cable work with sata III

[optical_mouse]

Hello,
I have new motherboard having the new SATA III ports. I have a new Seagate 1 TB HDD which is of SATA III (6 GB/s) . I was wondering if I can use one of the old SATA I cables off my old mother board for this. Do you think I can do this and if yes, will there be any performance difference ? Or is this too much of a risk.

Thanks!

The standards for internal SATA cables have not changed since SATA I. Go ahead and use the old cable.
Edit: I lied. The electrical standards have not changed. There is now a nifty locking connector that is less likely to work loose than the original friction connector. Physical compatibility allows either locking or non-locking cable to connect to locking or non-locking socket. If both are locking, you get a physical connection that is less likely to wiggle loose.

I think what happened was someone, perhaps Akasa, created these locking cables and I'm almost certain they've been around since SATA1.

They've become the norm thanks to high end motherboards throwing them in for free and eventually this has just filtered down to the entire motherboard range.

The locking connector is great though. The only issue I have with sata connectors is that for people who aren't particularly careful it can be easy to snap the connector off vertically. That being said the SATA connector is a million miles better than IDE!

But it's just like WyomingKnott said, the cable should work fine.
