This reduces the number of writes to the flash drive, but it might cause issues if a sudden power loss occurs when a high number of requests have been stored. ● Flush interval-Sets the amount of time during which HP Disk Cache consolidates disk write requests from the operating system before completing the requests (unless the flush count is reached first).
