I just upgraded from an M4 250 Gb to an MX500. The MX500 is performing incredibly slow, comparatively.
Here are a couple screen shots of what I am seeing. The M4 is out-performing the MX500 by 3x the speeds.
Each drive is using a different driver, but Windows 7 asigned the drivers automatically, and from my understanding, there should not be any specific drivers for either drive.
Anyone know what the possible issue may be? Thanks in advance.

Looks like its running at sata 1. What motherboard do you have? If it's nvidia based then that's a motherboard chipset flaw. Though I'm not sure how you'd have gotten the M4 to do any better in that case!
If it's not nvidia based, have you plugged it into the same sata port as the M4 was in? Some boards have sata ports of varying speeds/quality. You wouldn't want it in a jmicron port for instance.

I thought the SATA ports may come into play, so I went and downloaded the P6x58D controller drivers. Now, both the M4 and MX500 are using the 22.214.171.1244 Marvell 91xx SATA 6G drivers and both are getting ~130 Mb/s read and write.
It seems something goofy is going on, as the MX500 should be considerably faster.

After doing some further research, it seems that the 126.96.36.1994 Marvell 91xx SATA 6G Controller is garbage, and on the P6x58D, I'm better off using the Intel SATA 2 ports, what a shame. I was planning on upgrading, I guess I picked the wrong piece to upgrade first.

So here's a side-by-side comparison of the benchmarks I'm getting. Note that the M4 is now using the same Marvell controller and plugged into one of the two 6Gb ports. The MX500 is plugged into the other 6Gb port.
How is there such a disparity? It doesn't make any sense to me.
I guess I should note that I have Bitlocker encryption turned on, but that should only make a little bit slower...

I've never actually seen the MX500 on a Marvell port. But the M4 uses a Marvell SSD controller itself and the MX500 doesn't. So perhaps the M4 plays better with Marvells 'interesting' definition of sata 3??
But yes, in any case I would recommend the use of your chipset controller, even if its sata 2, over the onboard Marvell controller.

I would probably use Intel's SATA2 ports too.
How do both drives compare side-by-side on Intel's port? Did you try connecting them this way?
As for the driver for Intel controller, I wouldn't recommend installing Intel Matrix Storage Manager Driver that you can download from Asus support site. The driver that should work on your mobo is here.
