Question about SATA I and SATA II

[Pez D Spencer]

I have a 40GB SATA II drive and a 200GB SATA I drive. If I put them both in the same system will they run at independent speeds or will the SATA I drive pull the SATA II drive down to its slower speed?

I would assume that they will run at independent speeds because they are on separate channels.

Thanks for any info.

Independent Speed.
However, just so your know SATAII provide almost zero performance benifit as of today.

Agree with toattett...

Forgive my stupidity but may I ask why?

How about tomorrow? Is it just that current HDs can no where push 300gb/s or whatever SATA 2 is rated at? In other words the pipe size doubled, but it's still just a stream of data trickling thru.

Basically yes. The other features like command queing that SATA II offers don't increase single-user performance significantly either.

Actually features like NCQ, hot plug etc can be found on some SATA I drives as well...
