Rampage IV Gene w/RAID enabled, and optical drive use

post #1 of 2
Thread Starter 
On the Rampage IV Gene board, it has the following SATA ports:

  • 2 x X79 6.0 Gbps
  • 2 x X79 3.0 Gbps
  • 2 x ASMedia 6.0 Gbps

As I understand it, if I enable RAID on the X79 (for a RAID 0 setup for two SSDs), it'll enable RAID for all the X79 ports. Question is, will the DVD optical drive still work if I plug it into the X79's 3.0 Gbps port? I assume it would, but just had to ask to make sure.

Thanks.

Yes, it will. But no, you really don't want to do that.

RAID mode basically mean's the SATA is running in regular IDE mode on all ports...but with a extra layer of software/hardware that can RAID things.

Enabling the RAID controller on all ports doesn't mean you don't have to run RAID on all ports.

I ran into a similar issue, where enabling Intel's built in RAID controller on my HDD's forced my SSD out of AHCI mode and into IDE mode.

Sooo...enabling RAID with a SSD without AHCI mode disables TRIM and garbage collection. That means your SSD will seriously slow down after time. If you want to run a SSD in RAID 0, you need a expensive after-market PCI RAID card.

In my humble opinion RAID 0 for a HDD is very noticeable. RAID 0 for a SSD will almost never be noticeable, except in a few rare situations and in benchmarks. Sometimes going to RAID0 with SSD's makes your PC take even longer to boot, because the POST is longer as the RAID controller gets set up.

(A software RAID array will allow you to run AHCI mode and RAID 0,...but you can't do that with your boot drives. I run my 1Tb storage drives in a software RAID0 array, so i can have garbage collection on my SSD.)

That's my two cents.
