You don't state your purpose, so it's hard to understand what you need.

  • If you're trying to make copies of SD cards, e.g. as OS for a batch o microprocessors, there are SD drive duplicators.

  • If you're trying to simulate a "drive carousel" or CD/DVD array, be aware that flash memory is much slower than SDD or HDD, and more expensive than HDD. A large HDD could be partitioned into a virtual array of disks.
