On the Asus Rampage III Extreme, there are only two ports to connect two drives on 6 Gbps. So if I were to purchase one SSD and attach it to one of my 6 gbps ports and purchase another SSD like the Crucial RevoCard which is a PCI based SSD, would the system automatically detect the PCI SSD and use the other SATA III port for it to work. Or will the SSD card operate on its own and free up a SATA III port on my mobo to use for something else.
I know that I can use SATA II but I prefer the SATA III instead.
The reason I'm asking this question is that I have many different storage options I am considering for my first computer build.
I was going to purchase one 128 gb SSD and two VelociRaptors 10k 600 gb and put them on a Raid 0. But now I have three drives and only two 6 gbps ports. So I was thinking of purchasing a Raid controller card since it's supposed to support 6 gbps. I know I can downgrade the drives to SATA II but they were made for the SATA III ports so I want to utilize them to there most possible performance levels.
But if the Raid contorller card supports 6 gbps drives, when the card is installed in an 8x PCI Slot, do I have to connect the mobo's SATA III ports to the card or will the card have its own SATA III on it.
This is so confusing.
I don't see any mobo's out there that have more than 2 SATA III's on them. And with technology improving so rapidly, the mobo manufactures won't push the envelope and include more SATA III ports. Were very limited.
I hope I didn't confuse you with my question. If I did, I'm sorry.
I'm just looking for better storage options. I guess I can only utilize one 10k drive and one SSD or two 10k drives on SATA III.
Your suggestions and comments are will always be greatly appreciated.
No, you won't loose a SATA port if you use a PCIe based SSD; no connections required. However, I tend to prefer leaving my PCIe open for GPUs.
Ideally, the 128GB SSD + RAID 1 HDD is preferred; RAID 0 is a very risky place for any data. The WD VelociRaptor are not a good bang for the buck; instead I would RAID (4) 1TB SATA2 or SATA3 (no gain in speed for a HDD) 7200 RPM Samsung or Hitachi or WD RE3/RE4 HDDs.
DO NOT confuse 6.0 Gb/s / 3.0 Gb/s Interfaces with SSD/HDD speeds. Example your WD VelociRaptor is ~ 1/2 peak SATA2 Speed at ~ 145 MB/s.
