Hi all,

I've just installed an OCZ Vertex 3 120GB MAX IOPS into my machine. AS-SSD looks like this:

Other benchmarks seem to rank the Vertex 3 with ~500MB sequential incompressible read speed. I have an Asus Sabertooth X58, and hence a Marvell PCI-e 9128 controller. I've heard these controllers do not work brilliantly with the Vertex 3 drives.

My question: what PCI-e controller should I buy to improved my SSD speeds? (I do not need to use RAID).

Thanks in advance!

Gaming and programming primarily, still debating whether I have enough room to make it my boot drive.
 
Well, if thats the case the speed you're "losing" won't make much/any difference. Is the access time/small read/writes which makes the difference.

It'll certainly help with boot times/windows if its your OS drive. Do it! Put other programs on another drive if you have to. It's the better way round. windows will benefit far more than a game would from an SSD

Thanks. I'm reformatting next week to restructure my Data drive anyway. I'll put the OS on my SSD then.

Thanks for the advice!

Will do. Is there any specific settings I should be using?

I haven't rebooted since I installed it and I've moved about 70GB of data onto it in the past few hours if that affects anything...
 
As you have an i7 920 you must have an X58 motherboard.

X58 doesn't natively support SATA 3 so the SATA 3 controller you're using must be an add on from the likes of Marvell.

Add on controllers are notorious for not being able to provide the full SATA 3 speed of ~550MB/s.

In summary, the controller you're using will be restricting the speed of your SSD.

That is all true. My controller is a PCI-e Marvell. It is only 1x, so it's restricted to PCI-e 2.0 x1 speeds unfortunately. I know controllers such as MegaRAID 9240-4i are fast "entry-level" RAID controllers, but they're very expensive too (in fact, nearly as much as the SSD)

If there's no addon controllers that will do the job, I'll have to deal with my Marvell.
