Flashcache : ウィキペディア英語版
Flashcache

Flashcache is a disk cache component for the Linux kernel, initially developed by Facebook since April 2010, and released as open source in 2011. Since January 2013, there is a fork of Flashcache, named EnhanceIO and developed by sTec, Inc.〔(EnhanceIO: New Solid State Drive Caching For Linux )〕
Flashcache works by using flash memory, a USB flash drive, SD card, CompactFlash or any kind of portable flash mass storage system as a write-back persistent cache. An internal SSD can also be used for increasing performance.
== Overview ==
Using flash memory (NAND memory devices) for caching allows Linux kernel to service random disk IO with better performance than without the cache. This caching applies to all disk content, not just the page file or system binaries. Flash memory based devices are usually a magnitude faster than spinning HDDs for random IO, but with less advantage or even slower in sequential read/writes. By default, flashcache caches all full blocksize IOs, but can be configured to only cache random IO whilst ignoring sequential IO.〔(【引用サイトリンク】title=Flashcache : A Write Back Block Cache for Linux )
Similar technology exist in Microsoft Windows as ReadyBoost since Windows Vista.
