![]() The form factor options of a flash-based cache include a SAS, Serial ATA or nonvolatile memory express ( NVMe) SSD a PCI Express ( PCIe) card or a dual in-line memory module ( DIMM) installed in server memory sockets. The SSD write cache can boost overall system performance.ĭemartek President Dennis Martin explains the benefits of using solid-state storage as cache for hot data. The objective of SSD write caching is to temporarily store data until slower persistent storage media has adequate resources to complete the write operation. SSD caching can also be a cost-effective alternative to storing data on top-tier flash storage. Placing previously requested information in temporary storage, or cache, reduces demand on an enterprise's bandwidth and accelerates access to the most active data. The goal of SSD read caching in an enterprise IT environment is to store previously requested data as it travels through the network so it can be retrieved quickly when needed. A flash cache is often used with slower HDDs to improve data access times.Ĭaches can be used for data reads or writes. In a common scenario, a computer system stores a temporary copy of the most active data in the SSD cache and a permanent copy of the data on a hard disk drive ( HDD). SSD caching, also known as flash caching, is the temporary storage of data on NAND flash memory chips in a solid-state drive ( SSD) so data requests can be met with improved speed. ![]()
