Two things to look at when it comes to SSDs:
1) Cycle life
2) Refresh rate
HDDs are cheap and have exponentially longer storage life. SSDs are fast, but the data has to be refreshed (refresh rate). Otherwise it is lost. SSDs also have a limited number of times that a memory location can be written (cycle life). Granted SSDs are larger then advertised to hide some of this and both refresh rates and cycle lifes are increasing. They still can not go long term without being powered-up, or left in service indefinably. The best solution is a hybrid of both HDD and SSD in a single drive. HDDs are going to be around for a long, long time.
About the SSD shown in the posted article, according to the vendor, Samsung claims a 1.5 million hour MTBF (for what that’s worth).

Comparison of NAND-based SSD and HDD
Reliability on storage retention
Solid-state drive
“If left without power, worn out SSDs typically start to lose data after about one to two years in storage, depending on temperature. New drives are supposed to retain data for about ten years.[5] MLC and TLC based devices tend to lose data earlier than SLC-based devices. SSDs are not suited for archival use.”
Hard disk drive
“If kept in a dry environment at low temperature, HDDs can retain their data for a very long period of time even without power. However, the mechanical parts tend to become clotted over time and the drive fails to spin up after a few years in storage.”
