ssd 520 240gb overprovisioning

[idata]

Hi every one, i ave just bought 2 intel ssd 520 240gb. i want to configure them in Raid mode (mirroring). I want to use the overprovisioning on the drives, what should i do? is enough to format both drive in one partion of 180gb and left the remaining space unformatted?

do i have to do something else to enable overprovisioning?

thanks a lot.

Giuseppe, Something is not right, but there are several things to check before deciding the SSD is bad.

First we need to know the parts in your PC, or the model if you bought it already built. If you built it, what mother board, CPU, and operating system do you have? After that, you need to check which SATA ports on your mother board you are using for your SSDs, particularly the 520 and your X25. We also need to know what SATA mode your BIOS is set to, and what SATA driver you are using.
