I have a MacBook Pro with a factory SSD that runs Atto at around 3.1GB/sec. That's great.

But, I ALSO have a OCZ RevoDrive X2 PCIe SSD in an even faster desktop, but it runs only 300M/sec. I'd like to find out why the desktop SSD is only 10% as fast!

The PCI SSD is in a PCI slot (sorry I mean the current PCI Express that's used for graphics cards normally, I probably have the wrong acronym). When the machine boots I think it says that it is in the 4X lane or something similar.

I have two GTX1080s in there as well in 8X lanes if that matters.

What else shoudl I check? I'd imagine this drive should be a LOT faster.

Other facts: It's an i7-4770K @ 3.5Ghz in an ASUS Sabretooth Z87 mainboard with 32G of DD3 at 9-9-9-24-2T.
