How do disk and tape libraries differ in their storage mechanism?

  • Disk libraries use magnetic disks
  • Disk libraries use optical storage
  • Tape libraries use flash memory
  • Tape libraries use magnetic tape
Disk libraries store data on magnetic disks, allowing for faster data access but with higher costs compared to tape libraries, which use magnetic tape for cost-effective long-term storage. This difference in storage mechanism impacts data retrieval speeds and storage costs in Commvault deployments.
