Speeding up slow disks with SSD caching

Conclusions

An all-Flash solution is the fastest, but it is also the most expensive solution. Caches that significantly accelerate a large volume on the hard disk using an SSD are cheaper. This approach will work best where an application produces stable access patterns. The cache can contribute little with completely random, chaotic access that never repeats. Often the cache needs time to reach a stable state. If you work with Writeback, you need protection against the risk of data loss, so use a battery-backed cache.
