Corsair Force 3 SSD sata2 speed on sata3? 3 ?'s
Last response: in Storage
I'm not sure I'm getting the full performance of my SSD. I am wondering if my system is the bottleneck, if I have to change some setting, or if it's my SATA 3 controller causing problems somehow.
I recently purchased and installed a Corsair 240GB Force 3 SSD to be my new games drive. The drive specs state that it has a max sequential read of 550 MB/s and write of 520 MB/s. However HD Tune benchmark says my max transfer rate is 302.6 MB/s. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
I also have had a Corsair Performance 3 SSD for my OS/Programs since I built this rig. This drive is stated to run up to 365MB/s read. HD Tune is giving me a max transfer rate of 283.5 on this drive. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Now I know that the Performance 3 uses the Marvell controller and have heard that they aren't the best. From what I've read about the Force 3 series though, the "High performance SandForce SF-2200 SSD controller" is supposed to have great performance. I guess I don't even really know what the controllers do. I'm not sure if somehow the Force 3 is using the Marvell controller and its slowing it down.
I have both SSDs connected to SATA 3 ports on my MB, the Bios sees them as SATA 3 compatible, and SATA 3 is switched on. AHCI mode is also activated.
Is there some setting I'm missing, some way to switch from the marvell controller to the SandForce?
Can I even have a setup where one SSD is on a Marvell SATA3 controller and another is on the SandForce?
Can I get the rated speeds out of these SSD drives with my current hardware configuration?
My current rig is
ASUS Rampage iii Formula Motherboard
Intel i7 960 @ 3.2 GHz stock
Corsair H70 cooler
12GB of Corsair Dominator RAM
EVGA GTX 670 FTW

curious, speed slow-downs like this are typically from not being in AHCI or RAID mode, but I see you already have that set.
My next suspect would be the mobo. Being a first gen SATA3 board I would suggest (hesitantly) to update your firmware and see if that helps things.
Keep in mind also that you will never see actuial throughput of 550MB/s per drive. That is using ATTO which scores SSDs higher than most benchmarks, but at the same time you should be getting much higher than 300 for your max. I would imagine you should be able to at least get somewhere in the upper 400MB/s range.
Also, those are not SATA2 speeds. My wife's system is SATA2, with a Vertex3 SSD in it, and hers caps out just under 200MB/s, so you can rest assured that you are not having an issue on that front.
