Either is fine. The Samsung 840 evo is most popular now.
It's overpriced where I'm located. The two SSDs I wrote are the only ones that are priced OK.

The Crucial MX100 is faster and is well worth the extra $15
I saw it only has like 30 MB/s extra write speed over the Corsair. After all, it's not that 512GB one but the 256GB one.
I'm more interested in things like reliability. Everyday performance won't actually differ I imagine, but if it is really worth the investment then I'll buy it.
