Controller Settings for Nytro Cache Drive Current Write Policy Write Policy: Write Back, RAID 1 (optimum controller settings (default))/Write Through, RAID 0. A virtual drive property that indicates whether the virtual drive currently supports Write Back mode or Write Through mode. In Write Back mode, the controller sends a data transfer completion signal to the host when the controller cache has received all of the data in a transaction. In Write Through mode, the controller sends a data transfer completion signal to the host when the drive subsystem has received all of the data in a transaction. Nytro Write Back Caching RAID 1 Write Back caching: Delivers high application performance acceleration for write-intensive random I/O workloads (mirroring of Flash and losing half the total Flash capacity). Nytro Write Through Caching RAID 0 and RAID 1 Write Through caching: Delivers high application performance acceleration for read-intensive random I/O workloads. In RAID 1 Write Through caching, the application does not receive confirmation of the write completing until the HDD is written.
