When the work was selected controller with support for SSD+HDD in Adaptec series 6 (6805). Their implementation of the Hybrid RAID levels RAID1 and RAID10, where the entry occurs on all drives, and read — only SSD without bumping into the coordination of different speed reading from the HDD and SSD, and even reducing HDD writing speed if there are simultaneous reads and writes.
But, the series 6E does not support RAID5/6 is can series 7 (I needed only RAID10, therefore to overpay for unused features did not make sense).
That did not like — even when connecting a single disk controller initialisere, making it "empty", even if it the information is there (I understand that I can repair it, but it's unnecessary procedure). Home 16-port LSI controller maps the drive fine.
Although the hybrid version You do not plan to use.
Proceed from generation PCIe. Given that you plan to use SSD. After all, it is the bandwidth of the controller is very important. X8 PCIe 2.0 has a theoretical (in practice, you know, is always slightly below) the ceiling one — way 4Gb/s, which is 6 SSD quite yet, but for more — can already be a limiter. PCIe x8 3.0 in this plan is preferable, having a bandwidth 2 times higher.

A good choice!
