write-policy string • write-back: Write-back caching does not wait for data to be completely

preferred setting for a fault-tolerant environment because it improves the
performance of write operations and throughput. This is the default.
• write-through: Write-through caching significantly impacts performance
by waiting for data to be completely written to disk before signaling the host
that the write is complete. Use this setting only when operating in an
environment with low or no fault tolerance.

string Numeric equivalents for write-policy values.
• 0: write-through

applications that read and write large files in sequential order, such as video
playback and multimedia post-production video and audio editing
applications.
