The other thread about building an OS/2 hardware system got me thinking about where the current hardware I have could use a little "help".
All in all I have a working system, but as I toss the occasional upgrade at it here and there, the original foundational pieces are starting to show their age.
Case in point, the MSI motherboard (880G-E45) only has a SATA2 controller. A couple of years ago I installed a Samsung 850 Evo SSD and completely moved away from a HPFS386 setup to JFS. Working fine, no issues. But since 850 Evo is SATA3 capable I haven't really had the chance to benefit from that capability.
All the numerous arguments around whether a typical home user would benefit or not aside, the point is clear: SATA3 is faster than SATA2.
So I'm curious, has anyone attempted to use a PCIe SATA3 add-on controller card? If so, what chipset did you find supported on our platform, and was that in standard SATA or AHCI mode?
Here is the current output of SysBench for my 850 Evo SSD:
