Re: Solid State Disks for Databases

ramfs is different than SSD. SSD looks like a hard drive that just happens to be really, really fast and as you suggest often have battery and HD backups. ramfs is a whole file system that the OS maintains entirely in RAM. It was only suggested in jest by (I think) Mladden but the response is correct, ramfs goes bye-bye in the blink of an eye.
