Many SSD drives are longer-lived than advertised

Any solid state drive is going to lose some of its zip as it gets older, but just about any of them will last longer than the life-span advertised by the manufacturer, a test by technology portal Techreport.com indicates.
Solid state drives, which use no moving parts, can only have data overwritten in their memory cells a limited number of times before the cells stop working properly, meaning the data they've stored is lost.
Techreport.com took six devices - all from major names - and tested them to death. All lasted much longer than guaranteed. Two models even cracked the boundary of 2 petabytes (about 2,000 terabytes) worth of overwrites.
