To this point, the presentation has talked about reliability. Reliability can also be applied to the performance. Most SSDs operate with high performance if the drives are empty or fresh out of the box; once filled with data, drives can drop the performance to only a fraction of the specified values. Swissbit has reduced this effect by using an architecture that utilizes a DRAM for buffering the flash page translation table. This eliminates nearly 50% of accesses to the Flash because the physical location of the data will not be managed in Flash based tables; instead in fast and non-degrading DRAM based tables. Special caution has been applied to make these volatile tables power fail safe. The second step Swissbit has applied is using an increased overprovisioning, which means it will take about an additional 7% of the flash for added data buffers and as management area, reducing significantly the amount and frequency of garbage collection. This feature shrinks the user area, for example, from 256 GB to 240 GB. At the same time, it improves the performance and nearly doubles the endurance under critical workloads.
