Your customer would like to use ATA drives for their SnapSure SavVol. The I/O access pattern on the PFS is random read. They plan to access the checkpoints randomly as well.
What would you recommend?

  • A. ATA drives provide good random I/O performance; therefore would be a good choice for checkpoint processing as well as checkpoint access.
  • B. ATA drives provide good sequential I/O performance; therefore would not be appropriate for either checkpoint writes to the SavVol, or random access of the checkpoint.
  • C. ATA drives provide good sequential I/O performance and are suitable for writes to a single SavVol. Random reads to the checkpoint would not be appropriate for ATA drives.
  • D. ATA drives provide good random I/O performance which is important for copy-on-first- write activity; therefore would be appropriate for both checkpoint processing and checkpoint access.
