My 3 year computer is feeling a bit old and slow. I'm thinking the best upgrade for me is to add a SSD and move my OS from non SSD to SSD. The price at the computer store for Samsung 256G 830 and 840 is exactly the same, around $195 AUD (computer parts are more expensive here). Anyway I read Anandtech's 840 review and I'm a little worried about the drive dying and lower lifespan. http://www.anandtech.com/show/6328/samsung-ssd-840-pro-256gb-review/8 Has anyone had Samsung 840 for more than 3 months as their OS drive? If I want a SSD that lasts more than 3 years is important for me, should i get the Samsung 830 instead? I heard Samsung's are good (compared to OCZ). Or what brand recommendations for 256G.
