SSD and Price fights - Data Caching
Originally written by
- Another possibility - using SSDs as cache for HDD systems.
- This will place all writes onto the SSDs - which will slowly move them
back to the HDDs later on.
- This can be useful for applications that do mostly writes and less reads.
- Of for applications with a small active set (i.e. that read the same set
of disk blocks over and over again) - but with an active set too large to
fit into a host system's RAM.
