In general, the greater the number of mirrored pairs, the greater the increase in performance.

RAID 0 provides no data redundancy for protection against disk failure. – Useful for scratch files or other temporary data whose loss will not seriously impact system operation. – High performance is important.

7DEOH 3HUIRUPDQFH ,PSDFW RI &RQILJXUDWLRQ 6HWWLQJV FRQWªG Setting: Cache flush threshold (default 80%) Function: Sets the level at which the disk array controller begins flushing write cache content to disk media. The setting is specified as the percentage of total available cache that can contain write data before flushing begins. The cache flush threshold can be set independently for each controller. Note that available cache is reduced by half with cache mirroring enabled.
7DEOH 3HUIRUPDQFH ,PSDFW RI &RQILJXUDWLRQ 6HWWLQJV FRQWªG Setting: Cache flush limit (default 100%) Function: Determines how much data will remain in write cache when flushing stops. It is expressed as a percentage of the cache flush threshold. For optimum performance this value is set to 100% by default. This ensures that the entire amount of cache specified by the cache flush threshold will contain write cache data, increasing the number of write cache hits.
7DEOH 3HUIRUPDQFH ,PSDFW RI &RQILJXUDWLRQ 6HWWLQJV FRQWªG Setting: Cache read ahead (prefetch) Function: Sets the number of additional sequential blocks transferred into read cache each time a read I/O is performed. Read ahead can be set for each volume. Performance Impact: Read ahead can significantly improve read performance for sequential I/O transactions.
