The smartphone manufacturers continue to focus on improving the speed and number of cores that were presented to the processor for their products, the number of megapixels on the display screen as well as networking technologies such as LTE. It is actually capable of becoming the basis that the performance of a handset should be based on the hardware specification is not it?
Researchers at the Georgia Institute of Technology turned out to have another opinion to this statement, they argue that the type and brand of a MicroSD card installed in a device is the main suspect for this problem. Their latest study finds the fact that flash storage technology used is often a major cause of decline in the performance of a device up to 100-300 percent of ideal performance. One case even recorded a decrease in performance by as much as 2000 percent.
Hyojun Kim, a student who is pursuing a doctoral degree at the College of Computing at Georgia Tech and also headed the research project, concluded that the development of flash storage technology is still far behind when compared with hardware development for mobile devices. The source of the slow variety of applications such as Facebook or Google Maps was derived from the poor handling of the input/output random data of the software used.
An ideal solution to this problem is the use of PRAM (phase-change random access memory) that is able to reset the writing random data better. Another alternative is easier to rearrange the file subsystem, leaving an empty storage space to keep it neat and well ordered.
