Question re mixed SATA

[Celador]

Hi all,

As you can see from my sig, I am running a SATA-1 and SATA-2 drive on the same controller. My question is, given I am running the SATA-1 Raptor, will the SATA-2 drive still utilise its full 300Gb/s bandwidth?

Everything runs fine but someone mentioned the other day that they thought with both types running via the same controller, it would only run at the slowest speed and that my SATA-2 drive would only run at SATA-1 speed.. is this correct? Would I actually gain some benefit from replacing the Raptor???

Appreciate any help

Speed is drive specific, but seeing as 1.5Gb/sec is more than enough to saturate your existing bandwidth you wouldn't see any difference in practice. 1.5Gb/sec is 187MB/sec, you won't exceed that with a single drive (or get near it). Only if you move to RAID will you have a chance of exceeding the spec of SATA 1. The differences you do see in benching a recent SATA 2 drive are due to it being a faster, more efficient design - it's faster not because it's SATA-2 but because it's simply a better drive using newer technology. Even so, a single SATA 2 drive isn't going to give you anywhere near it's theoretical max of 375MB/sec.

Cool. Will stay as I am then; thanks for that )
