Hi,
bcache is like a huge hd disk cache residing in a flash disk.
http://en.wikipedia.org/wiki/Bcache
+++······································ bcache is a Linux kernel's block layer cache (hence the name, block cache), developed by Kent Overstreet. It allows one or more fast storage devices such as flash-based solid-state drives (SSDs) to act as a cache for one or more slower hard disk drives, effectively creating hybrid volumes.
It is designed around the performance characteristics of SSDs, minimizing write amplification by never performing random writes and by turning them into sequential writes instead – for both the cache and the primary storage. That helps in extending the lifetime of flash-based devices used as caches, and also improves performance of write-sensitive primary storages, like RAID 5. ······································++-
Has some one tried it in openSUSE? Do you know of some document?
I tried searching our site, but search is broken:

Carlos, No first hand experience, but I see it recommended for Linux in general from time to time. Often with multi-TB raid setups that bcache could be used with to accelerate things. It came out summer 2013 I think. The oS 13.1 userspace tools got updated to 0.9 in OSS-updates last Feb: https://build.opensuse.org/package/show/openSUSE:13.1:Update/bcache-tools.27... If you have a test machine, it certainly looks like it is worth a shot. Greg -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
