    3. MySQL and SSD
      • MySQL
        • Open source database
        • Very popular to Web-based company
      • SSD
        • Solid-state drive
        • 2006~2007
        • Very fast random access ( in theory )
          • Fit database characteristic
    4. Conculsion First!
      • Don't Use SSD to run database
        • At least MySQL...
      • Unless
        • I/O bound
        • Enough Budget
    5. SSD Spec
      • Mtron
        • MSP 7000, MSD 3000, MSD 1000
      • Memoright
        • MR25.2
      • RiData
        • Ultra-S, Ultra S-Plus
      • Transcend
        • TS32GSSD25S-M
    6. SSD Spec
    7. Test in real environment
      • Linux 2.6.18 (Debian, testing)
      • XFS, noatime, nodiratime
      • MySQL 5.1.{21,22,23}, MyISAM
      • Replication (Slave)
      • Data size: my boss said we cannot talk about real database size, so don't ask.
    8. Test
      • Warm up speed
      • Write speed (Replication write)
      • Read speed (Query)
    9. Comparsion
      • Mtron MSP-7000, Memoright MR25.2

      • Mtron MSD-1000
      • RAID0 10KRPM SATA (2 disks)
      • Others... (RiData and Transcend)
    10. Something interesting...
      • No, these won't appear in this slide.
    11. Suggestion Again!
      • Don't use SSD in Master server.
      • Don't use SSD in Slave servers unless need.
        • I/O bound that RAID cannot solve
          • In most cases, you need to buy books to optimize your query statements, not buy SSD.
          • In some cases, you need to reconstruct your architecture.
        • Budget
    12. Q&A
      • Any Question ?
