SSD with firmware upgrade under OpenBSD

[Claus Assmann]

I was about to buy an OCZ Vertex 2 SSD when I read that firmware
updates for that kind of SSD require some M$ Windows version.  Is
someone using SSDs with a high IOPS rate (the Sandforce controller
claims 45-50 kIOPS) which can be updated under some freely available
software? I would like to try an SSD as mail queue FS etc.
