A couple of months ago I tried cloning my existing fossil+venti to an OCZ Vertex 3.  I did the partitioning and setup by hand and everything seemed to go just fine: the arenas copied and verified, fossil initialized, and I could run and mount the fossil from the SSD, but whenever I tried to boot from it it failed very early on with "I/O error" and that was that.  I didn't have any spare time to mess around with it so I just stuck with the existing disk.

I was running a really bastardized mix of old and new boot software, so it's quite possible I screwed up installing the correct MBR and boot loader.  But it might also have been a problem with the BIOS or SATA controller on the motherboard -- it's a slightly ancient Supermicro Atom 1U, and it doesn't like SATA hard disks, either (it's currently talking to an IDE disk).  I didn't have time to try 9atom.

That said, the limited testing I did with the secondary fossil+venti showed it to be quite zippy, within the limitations of the surrounding motherboard hardware.  Certainly it was noticeably faster than the hard disk for, e.g., mk all.
