Sounds like nonsense to me...I find that the larger/newer hard drives...which does not mean SSDs...are at least as reliable as any old or new hard drive can be. I trust my 2TB drives much more than I do my 500GB and older drives.
When hearing things like this...you need to remember that hard drive failure has been...and probably will continue to be...a routine event in the world of computing. Anytime you have moving parts that are manmade...the stage is set for nonperformance, IMO.

Frankly...I consider articles like the above...to be pure smoke. Like today's "sportscasters", some people are trying to draw straight lines where the path is a curved one on a ridge or mountain.
The basic flaw with hard drives...can be removed/lessened by going to SSDs...which won't be perfect (what is?) but users will be able to have a much better feeling about the reliability of the device...than can currently be obtained with any hard drive, of any size.
