if you need to store data for several years on a shelf with rare backups, no "updating" of cells is possible and no one in their right mind will deal with this nonsense. Adequate people will simply buy a capacious HDD, which is also many times cheaper, without helium, and close the topic of storing their data for 10-15 years in advance, having copies on 3-4 disks at the same time. Plus, it is desirable to have the most valuable ones on BD, but in light of their low capacity (single-layer ones, because multi-layer ones are extremely unreliable according to tests), no one wants to mess with them until the capacity of BD discs grows to at least 1TB. Tapes are also inaccessible to ordinary people, due to the huge cost of read / write systems for them. Only the rich and business can afford them.
SSDs only make sense as system drives and short-term data storage. If your valuable data lies only on the SSD, consider that you have already lost 100% of them.
The only NAND technology I trust is MLC or SLC. But they have practically disappeared from sale. And no multilayer chips can bring them back to life, because. the capacity will immediately become 1.5-4 times lower, i.e. really reliable SSDs on MLCs cost an order of magnitude more than the same capacity in HDDs.
Until there are cheap and very capacious (from 10TB) MLC/SLC disks with a guaranteed data storage time of 10 years on the shelf, there is no talk of using an SSD for storing "cold" data if a person sane and tech savvy.

I would be very happy with very capacious NAND disks with a write once (or up to 10 times for example), but very cheap and with a shelf life of 25 years on the shelf, but no one has yet come up with such, as a replacement for DVD/BD.
