I see why people want the ports to be as fast as possible, but I really don't see the big deal. Plugging the optical disk drive that is used once a month into a slower port isn't a big deal at all. 6 Gb/s doesn't even really matter for platter based drives either.
The question then is who has a desktop with more than two SSDs? Not anyone I know. Certainly less than 0.1% of computer users have this setup so I can see why Intel would cut costs here.
I have 2 in my computer and would have been tempted to add a 3rd or even 4th in order to increase my capacity (currently limited to ~450GB of usable space) as my game collection keeps growing with all these steam and amazon sales (my steam games alone can add up to over 600GB)
I even have secondary computers with more than one SSD in them...
Honestly, not only do I want more than 2 x SATA6 ports, I'd like more than 6 ports total on the Intel controller. I was extremely excited when the initial rumors of X79 suggested up to 10 x SATA6 ports and was then very disappointed when it was a mere 6 ports with only 2 of them being SATA6.
Not that'd I'd fill up 10 ports with 10 SSDs, however I could easily see working with 4 SSDs and 4-6 HDDs. Right now I have to compromise and complicate things with 3rd party controllers or even consider forking over even more money for an add-on card.
While I'm excited s1150 chipsets will finally introduce all SATA6 ports, there's still only 6 of them, and will still be stuck with 4 cores on the CPU
