As capacity increases, cold data retention becomes more important than speed. Even pci-e 4.0 x4 is more than enough for 99.9% of the world's consumers.

But find an SSD drive with guaranteed data safety without cell refresh for more than 10 years with wear level of at least 30-35% and ambient temperature up to 55C is impossible with NAND techology.

SSD will remain a niche product for storing operational data, but not long-term. Even with prices falling lower than for HDDs with the same capacity, HDDs still have an undeniable advantage (at least they used to) - guaranteed data storage on platters for more than 15 years.

QLC and even more so PLC are dead ends of SSDs. Just like TLC in general.

I also remind technically illiterate ordinary people that it is essentially impossible to recover deleted data on an SSD - after the TRIM operation it is impossible, unlike a HDD with a PMR record, where nothing is lost even after a formal deletion in the OS.

Accidental deletion of data on the SSD leads to 100% loss of information if there is no online backup.

As well as the failure of the SSD is almost guaranteed to lead to a complete loss of information. It is almost impossible to restore it from an SSD even in specialized services, unlike a HDD, where the chances are very high.

And this leads us all (experts understand this) to the need to force the use of SSD RAID arrays, which further increases the price gap with HDDs for storing important data, even if they are operational ...
