This article is to show how simple is to use an SSD cache device to a hard disk drive. We also included statistics and graphs for several days of usage in one of our streaming servers.
Our setup:
- 1 SSD disk Samsung 480G. It will be used for writeback cache device!
- 1 Hard disk drive 1T
We included several graphs of this setup from one of our static media servers serving HLS video streaming.
The effectiveness of the cache is around 2-4 times at least!
