Depends what you mean, people claim the Samsung is maybe more reliable than other SSD's largely because if you look across various tech forums the number of posts about dead Samsung SSD's is low, relatively the same for Crucial and OCZ drives drop like flies.
This is in huge part because OCZ tend to jump on the latest controller before anyone else, which leads to teething problems and loads of returned drives.
as for ssd's being sold with reliability as a feature, its over HDD drives. Simply put electronic circuits fail at a lower rate than mechanical in the vast majority of situations. HDD's have mechanical moving parts that WILL wear out eventually and they have circuits, a controller and memory chip. SSD's have no mechanical parts so won't wear out in the same way, electronics can still fry but HDD's basically have an entire extra set of things that can go wrong.
SSD's are more reliable than HDD's but that doesn't mean you won't end up buying the one that dies.
IN reality SSDs/HDD's have low failure rates, its more important in business where downtime can cost you lots of money, at home, meh.
Reliability is pretty much the lowest priority reason to buy an SSD. Performance, noise, power, reliability in that order really.
Though also keep in mind for performance you'll not always notice a hell of a lot, its best in the worst situations HDD's have, unrar something while running a AV scan, and or running an encode, a HDD will crawl to a halt and just opening a webpage becomes a challenge, an ssd laughs at that.
Game loading, 5 seconds to load a level of 6, you won't really notice in most situations.
