SSD on optical drive bay or Hard disk drive bay - Any difference in performance?

[jtoh]

I just bought a new Mac Pro 6-core and an OWC 120Gb SSD drive.

My question is putting the SSD on optical drive bay or Hard disk drive bay, is there any difference in performance? My understanding from my old PC is never to share the SATA cable with the optical drive as it will take the transfer speed of the optical drive, because they are running in the same "channel"?

Is the 2 SATA cable in the optical drive bay 2 separate distinct ports/channel?

Is putting the SSD on the hard disk bay better as it will run faster?

Thanks.

Answers:

No difference.

Bad info... Maybe from IDE days?

Yes they are individual and separate SATA ports/channels.

No difference.

There is no priority or anything like that for the bays. I have my 120GB OWC SSD in the optical bay of my 12-core and its crazy fast.

ditto no issues and I tested each just to make sure with various setups

having 3 fast SSD sadly gets throttled big time though !

some quick snaps of how I put the SSD in the optical this time around ?

Even on a PC, you can't share SATA channels. The only sharing is PATA.

I did read this as wanting to use the extra port not sharing literarily

but ditto alphaod if you meant split it somehow ? thats not going to happen

Thanks for all the replies. I guess I am confused by those days where IDE rules.
