The first problem, you don't said how long you want to preserve the data without transfering it on another support!
Because, the longer you don't use the support the more you have these problems :
with HDD, the mechanical part, even when not used risk to jam. Happen for me to a HDD stored in a safe in a Bank
with SDD and other flash drive, especially when not in use, the data (electric / magnetic gate) evaporates
With opticalDisk, except some old cd made in real gold, the data will fade aways is in contact with light.
with magnetics tape, the problem will be the same as the flash drive, the magnetics elements will evaporates.
And with all these technologies, you will need the hardware to read and connect them.
You today are able to find a computer with a 8 inches floppy drive or even a 8 inches floppy drive or a computer that have the ide connector to connect the 8 or 5 inches floppy drive ?
My solution, is to backup and copy often. I transfert my backup support every year or two to a new kind of backup support. First tape and CD, then DVD, then BR, Then HDD, this year TB SSD are cheap enough to be in my near vision for the next backup. And I keep my older backup.
