Got one of theese as a replacement for a vertex 2e bigfoot that died after 15 months use. Refurb model that i havent installed yet. Is it worth keeping as im a bit wary of sandforce ssd's after having owned the vertex 2e. I know it would run a lot faster than my old 2e. Ive been pondering selling it to help pay for a samsung 840 pro 120gb.
