Flash memory controller This special chip manages the interface to the host device and handles all the reads from and writes to the Flash chips on the Flash storage device If the host controller is capable of supporting faster data transfer speeds the use of optimized Flash controllers can result in significant time savings when reading or writing data into the Flash memory For example Kingston uses optimized high performance Flash controllers in its Elite Pro Ultimate Flash cards and DataTraveler Hi Speed USB Flash drives e The host device to which the Flash storage device is connected to If the host device computer digital camera cell phones etc is limited to specific read and write speeds using faster Flash storage devices will not deliver higher performance For example using a Hi Speed USB Flash drive on a computer that supports only the slower USB speeds will not result in faster transfers In addition computers need to be properly configured to support faster transfers in both hardware and software In the case of a PC the system board will need to have built in Hi Speed USB 2 0 connectors and the Operating System e g Windows will also need to have the proper USB 2 0 drivers installed in order to be able to support Hi Speed USB transfers For details on USB Performance refer to Appendix A Flash memory product manufacturers provide x speed ratings for Flash cards However due to a lack of industry standards compa
