AHCI, IDE, SSD, BIOS and other Acronymns
Since most people don't use SATA 6GB/s Solid State drives there isn't as much doco on em as there are other technologies. Alas, I forgot to chuck my SSD in AHCI mode (even though AHCI mode is set in the BIOS (ASUS Rampage Gene III motherboard)). The Marvell SATA 6Gb/s controller is a seperate chip that appears after the initial POST set-up. As a result it needs to be configured independently.

This motherboard (ASUS Rampage GENE III) is pretty good. No serious issues. But Hard-rebooting the machine one to many times can cause the motherboard to think its failed at over-clocking and re-set the BIOS. Pain in the ass.
What's worse though is it can't seem to remember the Boot order of the drives plugged in.
I've got 4x 1.5TB internal SATA 3 drives and 2x USB2.0 2TB external drives as well as the 256GB SATA 6Gb/s drive (which is the primary). This is apparently more than the BIOS can handle because it usually sticks a random drive (often the externals) as primary boot drive when the BIOS resets for any reason.
Even if you save and then load the profiles, it doesn't save everything perfectly (also forgets if its in IDE, AHCI or RAID mode). Most annoying.
ALSO!
I've since lost the MALE <-> MALE USB connector for ROG Connect... What do i do now? I have to make my own since its such a non-standard connector. using a MALE <-> FEMALE connector would have been A LOT easier.

My original gripe here is that now I have to go through the not-guaranteed process of converting the SSD (which is running Windows 7 x64) to AHCI mode through some registry hacks and by changing the controller. I wish the default had been AHCI or that it'd have picked it up from the BIOS (as I assumed it would have).
Advantages of AHCI:
- Hot swapping - Would probably be useful if i was running in RAID, but i'm not. The SSD is my OS
- Native command queuing. - Great for magnetic disks to reduce access times... Not so relevant to SSD's...
Hmm... Maybe I shouldn't even bother...
I might test anyway. Just to see what happens. I've heard access times are increased if NCQ is enabled on the SSD.
