If you keep up with technology news, you might be mislead into believing that the SATA 6Gb/s interface was made obsolete by M.2 2280 form factor on the Peripheral Component Interconnect Express (PCIe) 3.0 interface. With countless computer systems still utilizing Serial ATA as the primary storage device interface, you can count on seeing it around for a years to come. Adding to its appeal is the cost of solid state drive technology, which has doubled its storage capacity per dollar from just one year ago.
The ADATA SU800 SSD is a 2.5″ solid state drive for the ever-popular SATA 6Gb/s interface found on mainstream desktop and notebook PCs. ADATA promises 560 MB/s read and 520 MB/s write speeds with their new 3D NAND technology, allowing Ultimate SU800 to deliver higher storage density and reliability than ever before. SU800 also features intelligent SLC caching, a DRAM cache buffer to boost transfer performance, and Low-Density Parity Check ECC. In this article for Benchmark Reviews, we test the 512GB ADATA SSD Ultimate SU800 against the competition.

Bandwidth Speed vs Operational Performance
Solid State Drive performance revolves around two dynamics: bandwidth speed (MB/s) and operational performance I/O per second (IOPS). These two metrics work together, but one may be more important than the other depending on the workload. Consider this analogy: bandwidth determines how much cargo a ship can transport in one voyage, and operational IOPS performance is how fast that ship moves back and forth. By understanding this and applying it to SSD storage, there is a clear importance set on each variable depending on the task at hand.
For casual users, especially those with laptop or desktop computers that have been upgraded to use an SSD, the naturally quick response time is enough to automatically improve the user experience. Bandwidth speed is important, but only to the extent that operational performance meets the minimum needs of the system. If an SSD has a very high bandwidth speed but a low operational performance, it will take longer to load applications and boot the computer’s Operating System than another SSD that offers higher IOPS performance.
