X18-M and X25-M SSDs do actually have the potential to slow after extended use? After the company flat out denied allegations brought forth by PC Perspective earlier this year, it has now quietly pushed out a v1.1 update for the 80GB and 160GB versions of the aforementioned devices. All we're told is that it brings along "several continuous improvement optimizations intended to provide the best possible user experience," but there's absolutely no denying what it's really aiming to fix. Intel still maintains that the likelihood of users experiencing any long-term issues are next to nothing, but we'd suggest applying the update just in case. Wouldn't want to be missing out on any lightning fast read / write rates, now would you?
