Creating an Ultra High Performance Tier of Storage with SSDs
Companies are starting to use solid-state drive (SSD) technology in a high-performance tier of storage called Tier 0.
Tier 1 storage, also known as production storage, can be considered the first class cabin for production data. Tier 2 and lower storage tiers were developed to handle data that is not quite as critical or does not need the performance characteristics of Tier 1 storage.
Now there's a new tier of storage: Tier 0. Tier 0 is solid-state memory-based storage which is used to improve performance beyond what current Tier 1 storage can offer. In the past, Tier 0 storage has been in the form of a RAM disk and was quite expensive. In fact, to justify the high cost of RAM disk, you had to not only know for certain that your performance problems were storage-based, but also be able to show a return on your investment in RAM disk.
Today, however, this is changing. The dropping cost of solid-state devices is making SSD technology more accessible throughout the data center. But while these cost reductions in SSDs are broadening the technology's appeal, the primary consideration for when a company chooses a SSD option is still performance.
