I have to throw this link up here. I just came across it and it's VERY helpful.
SFF Tables by Industry (PDF)
I'm looking at the 12 GBps connectors for SAS. I see the 8087. Why have all of thee other connectors. Are they all in play as far as connecting to SATA drives? Are these simply standards set by different companies?
For example, here's a controller on Newegg (hereafter "NE") that
Adaptec Series 7H Family 7805H PCI-Express 3.0 x8 MD2-Low Profile SATA / SAS Host Bus Adapter (HBA)
This HBA has two "SFF-8643 mini-SAS HD"
Just a more expensive cable?
Stick to SFF-8087?

I think you should ignore 12 Gb SAS stuff.
As you can see from that PDF, a 6 Gb SAS port like the 8087 has four 6 Gb channels. The SATA forward breakout cables have four ports and each channel gets a port. So that single 8087 port drives four 6 Gb SATA disks.
Those 7200 RPM SATA disks you already have in hand are nowhere close to capable of each pushing 6 Gb/s.
So just keep it simple, and don't buy for the future. Buy for today and when the future comes the things you might have bought now with the future in mind will be a bunch cheaper. And by then you'll actually know what you need instead of assuming / guessing today.
