Benchmark Results: I/O Performance
All of our Iometer tests are run with a queue depth of one, which is more indicative of what you might see on a notebook than a business server. As a result, the majority of our tests here favor the consumer-oriented drives from Intel and OCZ. Clearly, though, there is a progression from all of the SandForce-based drives down to Intel's X25-M and the slower alternatives.
Notice how far we have come from what many would consider a first-generation SSD? The G.Skill drive, based on JMicron's JMF602B, almost always finishes dead last. Only in the Web server benchmark do we see it peel away from the mechanical drives.
This chart is an excellent example of what SSDs do better than mechanical disks. A Web server very rarely writes data. Its main purpose is to deliver pages and graphics. As a result, the low latencies of solid state storage give SSDs a natural advantage.
