I have said it several times that the most secure way to conserve the SEED is, at least for me:
Create a Gmail account and add 2FA via a SMS to your phone number needed each time you want to access it.
Start a Linux Live DVD- like Linux Mint and use the latest version of Libre office there, write down your seed in such document, add a strong password to it, than this password protected document add it to a rar file with a strong password also. Than upload this file to your Gmail account with 2FA enabled.
You can install Electrum in the Live session and then restore it in your PC after finishing saving and uploading the file to your Gmail. This is how I keep my seeds as I have different wallets.
The password to be strong enough like at least 16 characters and to make sense only to you and not contain dictionary words.
I do similar, however, I use PGP encryption then upload it to the cloud.
Also, I memorized my seed... though not too sure how well I can remember it when I'm much older.
Yeah, if you are gonna store it in the cloud, you should definitely be sure to use some sort of encryption to secure it. I wouldn't feel safe storing my seed in the cloud in unencrypted form.
