This is a most excellent place for technology news and articles.
That number is a single manufacturer's performance target. It is not a guarantee of results. You might be able to get Intel to replace an SSD if it corrupts data in under 52 weeks (assuming you notice it) but your data will still be gone.
Hardware performance can and does vary by manufacturer, model, and production run. Even the nominally identical cores within a single CPU have slightly different operating limits. YMMV.
Note also: the 52 week target you quoted is halved for every 5° rise in temperature.
