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 and are suitable for writes to a
singleSavVol. Random reads to the checkpoint would not be appropriate for ATA drives.

C.
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.

D.
ATA drives provide good sequential I/O performance; therefore would not be appropriate for
either checkpoint writes to theSavVol, or random access of the checkpoint.
