Table 1. USB evolution (continued) Type Data Transfer Rate Category Introduction Year USB 3.0/USB 3.1 Gen 5 Gbps SuperSpeed 2010 USB 3.1 Gen 2 10 Gbps SuperSpeed 2013 USB 3.0/USB 3.1 Gen 1 (SuperSpeed USB) For years, the USB 2.0 has been firmly entrenched as the de facto interface standard in the PC world with about 6 billion devices sold, and yet the need for more speed grows by ever faster computing hardware and ever greater bandwidth demands.
With today's ever increasing demands placed on data transfers with high-definition video content, terabyte storage devices, high megapixel count digital cameras etc., USB 2.0 may not be fast enough. Furthermore, no USB 2.0 connection could ever come close to the 480Mbps theoretical maximum throughput, making data transfer at around 320 Mbps (40 MB/s) — the actual real-world maximum.

Dell SupportAssist Pre-boot System Performance Check diagnostics SupportAssist diagnostics (also known as system diagnostics) performs a complete check of your hardware. The Dell SupportAssist Pre-boot System Performance Check diagnostics is embedded with the BIOS and is launched by the BIOS internally.
Built-in Self-Test (BIST) helps determine if the power-supply unit is working. To run self-test diagnostics on the power-supply unit of a desktop or all-in-one computer, see the knowledge base article 000125179 at www.dell.com/support. Diagnostics The computer POST (Power On Self Test) ensures that it meets the basic computer requirements and the hardware is working appropriately before the boot process begins.
