This document summarizes different types of physical storage media and RAID levels. It discusses volatile primary storage like cache and main memory, and non-volatile secondary storage like magnetic disks and tapes. Tertiary storage includes slower media like magnetic tapes. RAID levels provide data redundancy across multiple disks for reliability or performance gains, with tradeoffs in cost. Common RAID levels include RAID 0 for striping without parity, RAID 1 for mirroring, and RAID 5 for block-interleaved distributed parity. Flash storage like SSDs provide faster access than HDDs but have limitations on write endurance.
