It works by providing an amount of high-speed, volatile memory used to store data destined for non-volatile storage on relatively slow hard drives or solid state drives. Write-back caching is particularly useful on traditional platter-based hard drives and RAID arrays where highly random write access is expected. It allows for writes to be buffered, masking the performance lo...")

It is a measure of storage performance used to indicate how many read and how many write operations can be serviced, on average, per second.
