Bitcoin wallet vs pendrive or Memory card.

[NotATether]

In my opinion, I find it quite stupid to store a crypto wallet inside removable media. First of all, it can easily be lost. Second, it will be found by customs if you are traveling. Third, USB media is more brittle than a HDD hard disk and can be corrupted more easily, thereby making it more susceptible to failure and so on so forth.

I don't know why people like to portray cryptocurrency on a pen drive in movies. Or why rich people even bother to give USB sticks with bitcoin wallets in them when they could just broadcast a P2P transaction. It is not logical at all.

Bitcoin is not stored on any device rather it is stored on blockchain,

Blockchain doesn't  exist in the thin air. It's kind of database which must be stored somewhere, in RAMs, HDD, SSD, any media which allows to store digital data. My copy of blockchain which feeds my node is stored for instance on 1TB SSD by Samsung. (In fact my node support two copies, the second one ( as a backup) is on 2TB SSD.

Depends on the media and the way which protects it. You may find how I protect mine.

The hardware wallet is designed for long-term security in balance, so we still have 100% control over our assets over our private keys.
The software wallet is good to use if you often make transactions or hide small cryptographic assets that you also have 100% control over.

While using flash drives, it is not designed to store cryptocurrency, and its cons are that it is also easily corrupted, and it is also easy to copy or lose our data.

It's true almost all devices doesn't include DVD player. But there are some company make and sell external DVD reader. Amazon even claim one of the DVD reader sold over 1 thousand in past month.

I can also find a bunch of sellers on Amazon selling VCR and VHS players, but that doesn't mean it's good idea to use VHS tapes and expect them to keep your videos safe in future.
And with strong enough magnets you can easily destroy any information stored on CD, DVD and hard drives.

Third, USB media is more brittle than a HDD hard disk and can be corrupted more easily, thereby making it more susceptible to failure and so on so forth.

There are some exceptions, for example Sandisk ExtremePro that is super fast USB stick that is in fact SSD drive, and they also have microSD format.

You're right, although i don't think it'll be obsolete that soon when bluray is still somewhat popular.

These mediums of storage still have their uses, of course, but they aren't as important as they once were. 10 or 15 years ago, people probably thought it would be impossible to have some cheap type of cloud storage. Now, you get 15GB for free on Google Drive with every account you create, and that's just one provider. We can have negative opinions about anything Google is doing, but it's still a fact. Internet speeds are getting faster and faster, making it easier to upload and download from clouds, and that's what most people prefer.

Yes, that's true, but at any time Google and other cloud storage companies could change their mind and offer less GB space, but I think that's unlikely at least for now., I've used the drive a lot as a backup for encrypted data.

Physical backups in steel will always be better due to their durability and resistance against the elements of nature, but I'd not exclude digital backups from my list, as you can encrypt them and be easier to access physically, which we cannot. depending on is just one form of backup.
Tips for exporting encrypted backups from a standard BIP39 or Electrum wallet here.

As for the OP, I found the question a bit vague, storing crypto on pen drives has always been possible, before BIP39 and to this day in some wallets such as bitcoin core, the form of backup is through keystore files encrypted with a password, this file contains the keys, descriptors to move the funds. There are thousands of ways to store this safely on digital media.

Now if the OP's question is to run full nodes on pen drives, although it has 2tb pen drives, it'd be more worthwhile to use an SSD, they are not as durable as an HDD, but they are more resistant than them as they do not have mechanical parts.

I also use Google Cloud Services to store some important files and encrypted data, with a 15GB limit on a normal or free account that is not enough for me,
because there are other files stored. Every month I always subscribe to get a larger capacity.

Using an M2 NVMe SSD may be the best solution, because it is faster and smaller physically.
But the price is indeed more expensive than ordinary SSDs.

This is my imagination, there is some kind of Flash drive that is powerful and resistant enough to record Bitcoin Core Node processing.

Powerful large Flash drives like SanDisk 1TB Extreme PRO Aluminum exist, but ordinary SSDs are cheaper, faster and more durable.

I'm not sure why the OP isn't considering USB external hard drives for backup purposes, because HDDs have a much better lifespan than the flash that you can find in a USB pen drive.

Probably the price. He is trying to find the cheapest possible solution. The problem is that if you want to save money on cheap hardware, you'll pay for it elsewhere.

Well, the OP can still make a tails OS USB and create a cold storage on a tails USB and if he manages to set it up correctly, then it would be a cheaper solution and a reliable one too.

However, as the OP is thinking of having a complete blockchain on his pen drive or storing his wallet directly on a USB drive, such a solution doesn't exist and/or isn't feasible/secure.
