Potential for SSD data loss after extended shutdown.

The data loss due to extended shutdown (over 3 months) would only apply to enterprise grade SSD.  Consumer class SSD storage can hold up for about a year.

For example, Samsung PM9A3, data retention is 3 months, see datasheet.

The responsibility and liability for data loss is with the owners/users.  You will never find any explicit guarantee from any PC makers that would covered data loss.  However, there are data recovery services, just search for it in your region.

Thank you for your answer.

What are the warranty terms and time?

Under normal use, will users claim compensation due to material loss?

Thank you for your reference, but I can't find any instructions mentioning or reminding users that data may be lost if the SSD is not activated for a certain period of time.

For Dell products, yes, in warranty contract, Dell did mentioned that software and data backup is solely customer’s responsibility DELL WILL HAVE NO LIABILITY FOR LOSS OF DATA, PROGRAMS, OR LOSS OF USE OF PRODUCT.

For common sense, if data loss had happened without any backup, they might not that important to you.  It's just a safe practice to have multiple backup for important data.

Do you have specific issue?  The question and concern you have are not pertain to home products.  You are asking for certain info that only applies to enterprise products, which have different warranty terms and services.  For data retention, IT folks already know to run their system with scheduled backup and monitoring storage media health status.  There is no one using enterprise SSD for long term storage.  

Edited:  Just notice that your thread title said extended shutdown but your question asked if leaving the computer turned on for a long time.  Can you clarify?

Thank you for your answer,

Whether the user has backed up data is a personal security issue, but if the SSD is used normally and the computer is not turned on for a long time, resulting in data loss, it is an inherent problem (even if the data is not important).

I am worried about the warranty (or even claim) for loss of data in the SSD due to long-term non-use of the computer, regardless of commercial or home use, without product description.

As I have pointed out, there is no such warranty for user's data.  Dell only provides warranty for hardware failure.  All storage drives will crash eventually from normal use.  If you did not know that, now you do and it is time to do back up if data is important to you.

I or community can assist with your computer issue but we can't fix your mental state.  If you worry about your data, just backup, backup, backup.  It's that simple.

Thank you for restating the warranty terms again.

I understand the importance of data backup and that it is the user's responsibility.

You mentioned before that it is more than 3 months for enterprise and 1 year for home use, but my question is that I cannot know from the Dell product description what is the storage period of SSD data loss?

A computer is not a permanent data storage device, therefore, computer makers provide only technical information for storage of the computer itself but not the contents of users creations.  Same thing with warranty, computer makers provide warranty for hardware but software support is a paid service.  If you plan for a long term data storage, search for products that specifically advertised for data storage. Similarly, you may learn something from eBay sellers, all their ads would state up front, what you see and what in the description is all you get.  Don't expect something else. 

You are asking about an issue that did not happened for a product you did not own or specify.  Nand storage is technically complicate for a simple short answer, considering with all required humidity, temperature, elevation conditions involvement.  Final words, there is no guarantee for user data from any storage product makers ever.  That is why users keep multiple backup.

Although you may not like all the answers, your query have been resolved with proper information.  You can close this thread for the solution of the topic.

If still interested, you can search for the subject and learn more about how NAND works.

Thank you for the information,

Different from HDD, according to the specifications, if the SSD data will be lost over time, does this mean that the OS will be damaged if it is not started for a period of time? But the problem is that the product description does not provide a reasonable time.

If Dell product fails during its warranty period, you can follow the service contract terms for eligible coverage and file a claim.  For anything else, no one is responsible.

While I already pointed you to the right direction (Dell warranty contract) and giving you the correct information (product data retention), it's pointless to discuss about issue that may or may not happen and some expectation that you expect to see.  If those types of description or advertisement does existed, would you point to an example of actual problem and expectation of description from HP, Lenovo, or any PC makers in the markets.

To recap, your question about a potential data loss was answered.  realistically, it's more likely to happen from a system drive crash, flood damage, fire, electrical surge, system hacked and theft.  Very little to no chance from the data just disappeared by itself.  Knowing that data can be corrupted and becoming inaccessible, there is no PC makers will provide warranty for data.  So, If that ever happens to you, there is no warranty.  If something you don't know, it does not mean other people faults for not telling you.

It may not be the answer you like to hear, but they are the answer to your question. 

To protect your data, consider Dell data storage product.

Thanks again for your explanation.

Although hard disk data cannot be guaranteed to be lost due to accidents, I believe that no user expects that SSD will be lost due to time (not read and write loss). It’s not just a backup, I owe it to the manufacturer to explain and remind consumers.

According to research, an SSD can retain your data for a minimum of 2-5 Years without any power supply.

So I would not worry about this too much. It's not that if you return from a vacation your data is gone. For offline backups, use HDD's or make sure the SSD's are powered on for at least one day per year.
