OCZ is nearly bankrupt based on this report I read however.. so I'd be concerned about that warranty holding water.. they're about to be kicked off the NASDAQ because they can't tell how much money they've made/lost for the last 2 quarters. Key staff (including the CFO) have jumped ship.
I'd have bought this if I hadn't read the details of their problems first
OCZ's financial situation seems pretty dicey according to that article, but I have never had problems with their RMA or warranty processes. I've even had DRAM, which OCZ stopped making in 2011, replaced not too long for a client of mine.
