There is really nothing to worry about with modern SSD's, they are projected to have very long lifespan based on testing. For example, take a look at this: http://us.hardware.i...pdate-20-6-2013
They did some serious endurance testing by constantly writing data to their SSD's for a long period of time. They had written nearly 800 TiB to the drive before they even ran into any problems!
TLC flash is basically the "lowest end" when it comes to write endurance, and even the samsung 840 which uses TLC flash seems to hold up very well when it comes to endurance testing, and its projected lifespan after the testing they did is very long, and most SSD's use the higher end MLC flash.
The idea that SSD's are "fragile" and will wear out quickly is false, and based on the reputation of first-gen SSD's. SSD's failing due to running out of writes is extremely rare, even for early SSD's, most issues were because of things like buggy firmware (and I also recall certain buggy dell BIOS's bricking SSD's and things like that)
There is nothing at all to worry about when getting an SSD.
Did they do anything similar for drives with MLC flash? I'd be interested to know how much the difference between the 2 actually is. The drive I currently own does use MLC flash but I'd be interested to know if the reliability justifies the extra cost
