The Storage Deep Dive

• SSD and HDD storage can be mixed to meet needs
  • A specific file cannot be in two places at once
• If using larger than memory data, RAID can be used to speed things up
  • RAID allows multiple identical storage devices to act as one
    • Mirroring increases read speeds
    • Striping increases write speeds
      • Some implementations allow for extra parity disks to protect against data loss
    • You can also mix and match striping and mirroring (usually mirroring a set of striped drives)
  • Can also help protect against data loss
