I have another question to ask everyone. USB flash drives typically use TLC, and after 2-3 years without power, it may experience data loss. So, how many years can a hardware wallet (like trezor one) retain data without power?
It's possible that ordinary users may not power up their hardware wallets for 2-3 years or longer.

I don't have an answer to your question since hardware failure depends on the hardware. I reckon it shouldn't be only 2-3 years but much more. I have no proof to justify my words though.
However, you shouldn't worry about it, since you can have a dual backup of your seed phrase and then you don't really care if the wallet (device) loses data. In fact, you can even destroy it and don't lose anything at all, as long as the only thing required to retrieve the wallet is your seed phrase and your passphrase (optional).
Personally, I have set my device to "temporary signing" meaning it erases memory when shutdown. So I use the "malfunction" that you ask for, as a feature!

I broke my previous hardware wallet by just not openly it for a year. Hardwallet needs to be open even once a month as per the general care description of the device. I believe the year of storing the data is not important since you can always recover all your assets stored on broken hardware by importing the seedphrase on any software wallet that support wallet import. The durability of the hardware wallet is your main concern rather than retaining the data inside since it will be there as long as the device is working.

Flash memory drives used in hardware wallets are not TLC so unlike USB which uses TLC (Triple-Level Cell)which is aimed to store more data in a cell has less durability and 3000 P/E cycles. Whereas hardware Wallets uses SLC (Single-level cell) which provides the highest endurance possible with expected 100K P/E cycles so technically it can last longer than the USB drives but I don't expect it to last longer, than 5 to 10 years because the durability is affected by various other factors too so even if you keep HW safe you need to have physical backup(s) of your recovery seeds.

I don't think so because the HW wallets are built to last long and the firstt thing that can break down in HW is the battery used to powerup which means lesser you connect the most life can be expected. So there is no reason for your HW to broke unless it damaged physically or exposed to extreme weather conditions.

What that is most important is to have your seed phrase with you. If you have your seed phrase with you, you will always have access to your coins. If a hardware walket is no more working, you can get another one and import your seed phrase into the new hardware wallet and you will be able to have access to your coins. Seed phrase will last forever.

I rarely find relevant data in the user manuals. I bought three high-end encrypted USB drives, two of which are 32GB for $25, and the customer service told me they use TLC. The other one is 8GB for $40, and even the customer service doesn't know what type of flash memory it uses.

So I am very concerned about the longevity of the storage medium.

If it use SLC, then there's nothing to worry about. There's still plenty to worry about. Hardware is not perfect, and I've had plenty of devices over the years fail on me long before they "should" have. There are also plenty of other components in the hardware wallet which could fail before the storage. There are lots of reports from Ledger and Trezor users of the screens failing, for example. The issue is that the backup of the mnemonic phrases is also partly stored in an encrypted electronic format. So I am very concerned about the longevity of the storage medium. It shouldn't be. It should be backed up physically on paper. Good quality paper and ink stored away from extremes of heat, humidity, etc., will last for decades. Laminate it and it will last even longer.

The hardware wallet is not just any other USB, it is specifically designed to store the data stored in securely even if the device is connected to a malware-infected device. Of course. every electronic device has a life span but all I am saying is Hardware wallets can last longer than any USB you can because of the type of NAND used and it is specifically designed for that purpose The issue is that the backup of the mnemonic phrases is also partly stored in an encrypted electronic format. So I am very concerned about the longevity of the storage medium.
You are not supposed to store the recovery seeds in the same device cause it voids the actual purpose of the recovery seeds.

[/quote] Paper-based storage of mnemonic phrases can last for several decades or even centuries, but it also carries risks. For example, what if there is a fire? Perhaps this risk can be mitigated by using metal instead? Another risk is theft. We can try a different approach. For instance, we can write down 15 out of the 24 words on papers. And encrypt the remaining 9 words (using WinRAR or 7-zip, AES256 encryption, with a strong password) and store them on encrypted USB drives and in email accounts. The papers can be sealed and stored in several locations, so even if a fire occurs at home, there is no need to worry.

So, how many years can a hardware wallet (like trezor one) retain data without power?
I have encountered somewhere across mentions of something like ten years of average lifespan for non-volatile memory used in HW, but you have to take into consideration that to prolong memory's life device should be kept at optimal conditions. The loss of charge in memory cells is temperature dependent - the higher the temperature the faster the leakage. Probably, keeping it in fridge (and preventing from being exposed to moisture there ) will increase memory's life .

Paper-based storage of mnemonic phrases can last for several decades or even centuries, but it also carries risks. For example, what if there is a fire? Then I go and recover one of my other back ups and use it to replace the lost back up. You should never only have a single back up. Another risk is theft. Then use a passphrase or multi-sig. Then the theft of one back up is insufficient to compromise your wallet and steal your coins. For instance, we can write down 15 out of the 24 words on papers. And encrypt the remaining 9 words (using WinRAR or 7-zip, AES256 encryption, with a strong password) and store them on encrypted USB drives and in email accounts. This is an bad idea. Overly complicated, zero redundancy, significantly increases the chance that you are unable to recover your wallets. And where are you planning to back up your strong password?

If it was made using 'good' hardware. If then went cheap, then you never know.... The other thing to keep in mind is the battery if it's not USB powered. Lithium batts can get so low that they just die and can't be recharged so you have to take the wallet apart and install a new one. Or if it's one that takes regular batteries, make sure that they don't do the sit for years and leak all over everything death. And if it has a screen I think everyone has had at least one cell phone / monitor / whatever screen just up and die. So, it's not just the data but the unit as a whole. So MAKE SURE YOUR SEED IS SAFE. -Dave

It's possible that ordinary users may not power up their hardware wallets for 2-3 years or longer.
This question must be asked first of all to each specific manufacturer of HW devices. It's surprising that users of trezor and ledger (the most popular and widespread) hardware wallets haven't done this yet. What prevents you from periodically turning on the HW device? This process takes very little time. In addition to having backups of seed phrases, it is necessary to have alternative action algorithms in case you need to immediately gain access to your wallet with crypto assets, and the HW device is broken (the display is broken, the internal drive is out of order, or something else). That is, how will you restore your wallet? Using a reserve hardware wallet or a crypto wallet app like electrum.

Keep in mind that some hardware wallets may have an internal battery, so their memories can store information for a probably longer period. However, when it comes to preserving information for the long haul, there is nothing quite like the reliability of good old-fashioned paper. Or even better, a sturdy piece of metal with an engraved message.

This is an bad idea. Overly complicated, zero redundancy, significantly increases the chance that you are unable to recover your wallets. Maybe everyone has their own methods, and of course, you are more professional. Here are my thoughts: Firstly, writing down all the seed phrase and passphrase on paper or separately on different papers, and then making multiple copies and keeping them at home makes me feel insecure. So, I choose to write a portion of it on paper and encrypt another portion as an electronic file. Each part have several backups. As long as one copy of each part survives, the wallet can be restored.

Yeah, you are right having multiple copies is not secure however you can encrypt your backup seed with custom/extended word even if you have multiple backups if someone finds your seed backup without the extended word he won't be able to recover your wallet. Just make sure that you memorize the extended word and don't include it on the piece of paper where you write down the seed.

A portion, like passphrase should be encrypted into electronic documents. Backing up everything on paper or metal is not secure.
