Berlin (dpa) – 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 two petabytes (about 2,000 terabytes) worth of overwrites.
Under normal conditions, where files are not constantly deleted and replaced, a standard user would need 1,000 years to reach that upper limit of data overwrites.
The first device flopped at 728 terabytes. Another automatically turned itself off after 750 terabytes of overwriting. In each case, warnings popped up about the drive failing long before any data was considered unsalvageable by testers.
Since they don’t use rotating magnetic discs and are considered more durable, SSDs are becoming ever more popular. They are growing more common in more expensive computers, but they are more expensive than normal drives.
