Hooking up an Intel X-25M (2nd Gen) 80GB SSD to my Gigabyte GA-P55-UD3R. I know I'm supposed to use the lowest channel available, but not sure which set of SATA headers I should be using. The options are:

1) The headers controlled by the P55 Chipet (six available)
2) The headers controlled by the JMB362 PCI Express controller (two available)

I need to hook up an additional 3 SATA devices:
-1TB WD Green drive
-DVD Burner
-eSATA front panel connector for case

Thanks

So does this look like a good setup?

Gigbayte SATA Headers (P55):
Channel 0: Intel X25M
Channel 1:
Channel 2: WD 1TB Green
Channel 3:
Channel 4: eSATA front-panel connection
Channel 5: DVD-R/RW

Any reason to use the JMicron header instead?

Note - if you have Win7 and want TRIM enabled, you have to use the stock Windows storage controller and enable AHCI in the bios. The Intel ICH storage controller doesn't have passthrough TRIM support (neither does JMicron). If you're using any other Windows OS, or just plan on using a garbage collection app, don't worry about it.

Thanks - I'm running Win7 X64. I didn't install the Intel storage drivers and I think I'm using the default MSAHCI driver (that's what shows in the benchmarking I've done).
