Asus Crosshair iV & SSD question...
Well, I am about to press the "purchase" button. Haven't built a system in several years so I spent the last several months researching (and catching up on technology), and this is what I have come up with:

Motherboard: ASUS Crosshair IV Formula
CPU: AMD Phenom II Black Edition 6-core 1090T
Videocard: AMD Radion 6970 (when its released next week?)
RAM: G.SKILL Ripjaws Series 8GB (2 x 4GB) DDR3 1600 7-8-7-24 F3-12800CL7D-8GBRH
Harddisks
(2) Western Digital VelociRaptor 600GB SATA6
(2) Western Digital VelociRaptor 300GB SATA3
PSU: KINGWIN Mach 1 ABT-1000MA1S 1000W
Cooling: Noctua NH-D14 120mm & 140mm SSO CPU Cooler

but at the last minute I am thinking of adding a SSD:

Crucial RealSSD C300 CTFDDAC256MAG-1G1 2.5" 256GB SATA III MLC Internal Solid State Drive (SSD)

My understanding is the SSD can be updated to SATA6 but the WD 300GB VelociRapters are SATA3. Do all hard drives have to be SATA6 to achieve those R/W speeds or will my WD SATA3's slow the whole board down to a SATA3 level (hope I am making sense here).

Does the build look like it will all work together? Any feedback on the new build most appreciated.

The SATA ports should work independantly, so a mixture of SATA 1/2/3 should not impact on other ports. :)

SATA ports work independently of each other (aside from pairs looking like a master/slave relationship to the BIOS, like old PATA drives) so one device plugged into one should not have a bearing on devices plugged into the others.

(Unless, of course, you're reading/writing so much data you completely saturate the available bandwidth on the controller... which, frankly, isn't likely...)
