Web-Server, File-Server Patterns

SSDs are tested under loads typical of servers here. The names of the patterns are self-explanatory. The results are presented as performance ratings which are calculated as the average speed of the tested SSD at every load.

These tests suggest that when the load doesn’t include many write requests, SSDs with four flash controllers are preferable. But when the load is far from pure reading, it is the total storage capacity of an SSD that's important unless you have some queer product like our custom-made JBOD-based sample. Why? Because when there are a lot of writes to be done, a larger pool of spare memory blocks provides a higher overall performance.

As a side remark, it is really amazing that you can go to any computer shop nowadays and buy, for quite a reasonable sum of money, a disk capable of processing as many as 20 thousand requests per second!
