JMicron is okay, it's an AHCI compatible controller, so does not even require
its own driver module, it just uses 'ahci'. Keep in mind that it is not a
PCI-E 2.0 device, and the transfer speed will be limited to 250 MB/sec over
both ports (and because of various overheads, something closer to 200 MB/sec).
A couple of modern disks can easily reach and become limited by that.
I suggest that you avoid Silicon Image 3132, they have data corruption issue
(on some board designs?), triggered or amplified by transferring via both
ports at the same time, at full speed.
If you can spend a bit more, try finding a controller based on Marvell 9123,
which is a 2-port SATA3 chip for PCI-E 2.0. For example "ASRock SATA3 Card"
which is sold separately (from motherboards) for about $33.

The only downside of that device, is that it doesn't seem to be compatible
with PCI-E 1.0, it is 1.1/2.0 only, so will not work on many old motherboards.
