SSD uses nand flash memory of the type QLC or TLC, is this type of memory organic or inorganic material? if i have two SSDs one for use and the other one stored ssd reserve, what is saved after years of use will the memories be totally degraded if it is organic making the device useless? does this type of memory automatically degrade even with electronic conservation care?

What does the datasheet say?

SSD have limited life in use or as stored data when powered off.
From our experience around 3-5 years seems the powered working life of a SSD , hence why most makers offer 3 or 5 year warranties.

A simple web search shows that data retention went powered off is quiet low, eg some sites suggest 1 year.

Seems a HDD or CD ROM would be a much better medium for long term storage without power.

With any backup plan, its wise to re-read and re-write the data every year or so.

Not aware of any Organic SSD or memory chips in general PC use.

If I buy two SSD drives, could I keep one drive for many years without chemical and organic degradation of the QLC or TLC nand flash chips? does the SSD degrade stored unused?

Every type of computer storage device has a finite life in respect of retaining data, powered or unpowered.

Long term data retention always been a problem from the days of Magnetic Tapes, Floppy Disks, Hard Drives, CD ROMS. Memory Sticks and todays SSD.

The hardware itself has a finite lifespan, which can often be established in pracrical terms by the warranty period the manufacturers offer, or theorectically , details of such lifespan in terms of r/w operations etc can be found in their datasheets as gophert mentions.

If your question is a practical one then why not say exactly what data you are tying to protect ?

If more academic, then keep searching the web for such info, unless someone else comes along with more details for you.

Is it possible to prevent data recorded in flash memory from being erased for long periods without power?
Define "long periods" with numbers and units of measure. Then simply compare to the values in the manufacture's datasheet.

If a drive is stored at 25C or operated 40C, expected data retention for SSD is 105 weeks, or nearly two years. Let the storage temperature creep up to 30C, or 86F, and the drive should still hold data for an entire year. Enterprise SSDs, however, have entirely different characteristics.

Enough of this memory data retention nonsense!
You are just wasting everyones time by trolling.
Be gone with you, - BANNED.
