from what I have read, wear-levelling is built into the drives and done without the OS knowing it is happening. I don't recall ever reading an SSD drive is good for DB type work though for that specific reason. I also read a great article that details the specifics on how SSD's work with the pro's/cons here: http://www.anandtech.com/storage/sho...spx?i=3531&p=1
Without knowing more details about your project, it is difficult to offer other solutions. If however you have a high tolerance for lost data (say 12 hours of lost data is acceptable), what about running TRX logging or similar on a ramdisk and only committing to disk every 2 hours or so.
