I'm looking to pick up a SSD for my i7 system to improve its real-world responsiveness. I think that since I also have a 500GB HDD for it, a 64GB SSD would be plenty (enough for Windows, Firefox, Office, Notepad++ and a game or two). I'm tempted by the Samsung 840 Pro 64GB, but it strikes me as expensive given the capacity. I suppose that for a 120/128GB disk I could spend up to $130, but I'd ideally like to spend $90 or less on a 64GB disk. Maximum speed isn't my primary concern; instead I'd like to make sure I get something with promising reliability.
