Storage is the hardware that retains data persistently, beyond power cycles, and it ranges from embedded flash on MCU platforms to enterprise SAN arrays. Two technologies dominate it: magnetic platters (HDD) and NAND flash (SSD).

A cache layer absorbs hot reads and coalesces writes before they hit the slower medium. The OS abstracts raw blocks into file systems, and DMA moves bulk data without burdening the CPU.
