- 01:54, 16 August 2023 Write-back (hist | edit) [2,012 bytes] Digimer (talk | contribs) (Created page with "{{header}} Write-back caching is a technology used in disk storage to improve performance. 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. This measurement is particularly important for storage backing services with highly random reads and writes. To learn more: * [https://en.wikipedia.org/wiki/IOPS IOPS on Wikipedia] {{footer}}")

This section uses language specific to two node split-brain conditions, but "node" could be replaced with "partition" to describe a subsection of a cluster and still be accurate. A split-brain is a state in which two nodes lose contact with one another a...")

Binary uses only '0' and '1', which relates to an electrical 'low' (0) or 'high' (1) signal. This can conceptually be extended to 'false' (0) or 'true' (1).
