Could you backup those claims?Sandforce is about 5% faster than Indilinx on average, which is very fast to begin with. The perceptible difference between RAIDed SSDs (like the Revodrive) and single drives is near zero.
I don't like bridge chips too, but it looks like this "fakeRAID" solution does allow TRIM on FreeBSD. Been following a discussion on the FreeBSD forum, and one of the positive sides of Silicon Image is that is can be used as normal AHCI SATA controller under FreeBSD. If i'm right you'll see two disks (ada0 and ada1) - as there are two Sandforce controllers on the board. Both should be TRIM-capable.I'm personally excited for when OCZ starts making things like photofast's drive which uses a much more powerful raid controller, or better yet maybe someone will make a native PCI-E SSD controller (is that even feasible?).
Don't get me wrong, the RevoDrive puts quite a bit of performance into a cheap and manageable package, but I can't help but feel leery about the SiI3124 PCI-X to 4 port 3Gbps SATA controller. I know PCI-X bridge chips are cheap but it just doesn't seem like an elegant solution.
