Rampage III Gene SATA6 question

post #1 of 4
Thread Starter 
I'm thinking of getting an SSD for my boot drive. I heard that on the Rampage III extreme, the Marvell 6GB/s SATA ports won't work for booting and purchasers are stuck using the Intel 3GB/s ports for that purpose. Can anyone with a Gene confirm whether or not this problem extends to this mobo? If so, is it worth running an SSD to a 3GB/s port or should I hold off?

I don't have that board, but afaik the Marvell chip can boot and use an SSD. It's just slow and lacks TRIM support, which is why some use Intel 3Gbps ports.

Today a 6Gbps SSD is not much more expensive than a 3Gbps. In the idea that the SSD you purchase might be used with the next build you should get the 6Gbps drive. Even if now it's used in SATA2 mode it wouldn't be any slower than a native SATA2 drive. It's your decision and to put things into perspective think that in access times and random IOPS a 3Gbps SSD is hundreds of times faster than a HDD which reflects into a noticeable performance in real-world usage; a 6Gbps SSD isn't visibly faster than a 3Gbps SSD in common tasks, not like any SSD is vs a HDD.

Marvel lacks TRIM support? Wow... Ok, Intel 3GB/s SATA it is. Thanks!

Yeah I have the same chipset- Marvell 9128...
I have also held off on a Vertex 3 because of this...

That SSD runs sequential reads at over 500MB/s but with the Marvell chip, is limited to ~400MB/s AND lose TRIM...

To tell you the truth, the newer sandforce controllers are so advanced with their GC (Garbadge Collection) that TRIM should effect it much...

With the limitations and problems I heard with Vertex 3's, i might just head onto two RAIDED Vertex 2's (about $100 each) and be happy with that performance as it will max out SATA II...

I use the Marvel 6GB chipsets for conventional HDD's for bigger storage even though they aren't too fast

love how quiet those drives are though...
