Well I don't exactly feel like dumping something I bought about 3 months ago.... I was thinking that a page file on the SSD would be safe because if the SSD fails windows will automatically make a page file on the hdd. Also using an SSD as a boot drive on vista is a no go for me (no TRIM!).
If it is only 3 months old, it should be under warranty. Try to rma it. Chances are, that OCZ will give you a better replacement.
No trim is not an absolute killer, particularly if the ssd has background garbage collection, or you don't do many writes.
Try it for Vista or the page file and see which works out better.
