The Latitude E6220 laptop’s six-cell, high-capacity battery provides nearly 7 hours of power, its blazing 320 GB Samsung PM810 Solid State Drive (SSD) boots Windows 7 in 31 seconds, and its PCMark07 score of 4,138 – a Windows PC benchmark rating – signifies it performs about twice as well as the average for laptops in its class against a rubric comprising memory, hard disk drive (HDD), system crunch, video encoding/decoding, and CPU standards. Consisting of thermoplastic polymer, powder-coated magnesium alloy, and anodized aluminum, the Dell Latitude E6220 laptop’s case affords no flex in its screen hinges, palm rests, touchpad, and keyboard.

The Dell E6220’s SSD offers significant advantages compared to a standard hard disk drive (HDD). The Samsung PM810 SSD uses flash memory to store information, giving it better performance that laptops with HDDs, and it has no moving parts, making memory damage from drops and bumps a nonissue. SSDs run at about 100 times faster than HDDs, with the PM810 touting sequential read and write speeds of 247.8 MB/s and 241.2 MB/s, respectively. A dual-core Intel Core i5 2520M, which runs at 2.5 gigahertz and has 3 MB of cache memory, powers the Dell Latitude E6220 laptop. The high data speeds provided by the SSD pushes the E6220’s performance to equal that of faster dual-core CPUs in the same family, such as the Intel Core i7. With Intel Turbo Boost, which dynamically overclocks and underclocks the CPU as needed. For example, when running a high-resource, visually intense program, such as a streaming service, Intel Turbo Boost overclocks the processor for increased performance. When running a low-resource-type program with modest graphics, such as a word processor or spreadsheet, it underclocks the processor to conserve power. For the full connectivity of a desktop PC in the E6220 laptop, Dell offers the E Series PR03X Docking Station.
