Manufacturers can come up against unexpected problems when faced with the various methods of clocking that are encountered within a test environment. As PCI Express (PCIe) has evolved, the speed of the clock (and therefore the data rate and bandwidth of the bus) has increased six-fold from Gen1 to Gen4. Further, the methods of clocking that may be encountered can vary substantially, making testing very challenging. In fact, there are six different clocking methods that engineers are faced with in any test bed and these all must be factored in during QA testing.

The easiest and simplest solution to this common problem is to use the SANBlaze SBExpress-RM4 (Gen4) test platform that has clocking tests built right into the system, allowing SSD manufacturers to not only save time and cost, but to ensure their drives are thoroughly-tested and compliant.
