Yes, you need S/ATA ports...but only one of your drives need to be S/ATA3. The 3TB drives are spindles and still fine on the plethora of S/ATA2 ports both Intel and AMD have. There's not a single spindle drive that breaks S/ATA2's cap, including the 1TB Raptor. Your 3TB drives are just fine on the common ports.
My point was that it's very rare that anyone has more than 2 SSD's that need S/ATA3's speed in order to spread their wings, so just two S/ATA3 ports are really fine. If they're RAID'ing SSD's they also need to have an external card as it's still software RAID using the onboard ports. The H77-I has 6 ports, so I'm not saying Intel has a shortage of ports in general, but only two are S/ATA3 where AMD has a herd of them. In a world of really freaking fast SSD's and 4TB spindles, I just don't see the need for a bunch of ports...or towers to hold them all in general.
I'm a big pusher of growing smaller. My mATX case has spots for 4 drives + 1 SSD, then two external drives. With 3TB really being optimal currently with the prices, that's 12TB's I could shove in there and never use. What is anyone going to do with 8 S/ATA ports of any flavor? Two are generally just fine.
I wouldn't hold my breath on SSD prices dropping any lower than they are now. It's kind of a standard now and 1TB is still way off in the horizon as far as decent pricing goes. $1 a Gig is current and you'd need to get to $.25 a Gig in two years to be applicable; I just don't see it happening like that. SSD's aren't meant to hold stagnant files. They can, but that's just not stuff you need that speed for (think of a Ferrari to go shopping with). A 1TB spindle drive can cost $50 and we're nowhere close to that type of product when it comes to SSD's. We're still battling the $120 for highend 128G SSD's (Midlevel having 256G at the same price point)...that would be $1,000 currently for a 1TB. I just don't see that happening any time soon.
