Solid State Drive technology is unfamiliar to many consumers, and so long as there are different ways an SSD can operate there always be questions that need answering. Benchmark Reviews offers various SSD tests, but proving performance speeds and matching manufacturer claims is only part of the story. Each SSD processor has unique behaviors, with some working well with TRIM and offering improved performance in AHCI mode, while others include Garbage Collection (GC) and work best in IDE mode. In this article Benchmark Reviews demonstrates how SSDs are tested by the manufacturer, and illustrates how real-world performance is different for end-users.
