Micro SD Cards are sure to have their share of being forgotten, often misplaced and eventually lost. However if your reasoning is because they have limitations (individually) but if you want to widen the scope, you can use them as a recycling hinge of sorts when paired with a 2.5 SATA drive.
This is assuming that the SATA drive has drive bays, normally four of them. By placing a card/s on the four slots (which could give you as much as 128 GB), you can expand the possibilities with the additional storage of the said drives.
This collection of microSD cards can be used as a boot disk for your operating system or storage, depending on your need/s. Sound geeky so if you aren’t that techie, maybe someone with a more technical mind can lend you a helping hand.
