Companies making billions of smart phones in the world, normally focus on speed,processor cores, network technologies (Edge, 3G, 4G) or how many megapixel camera is installed. The performance of the phone is mostly based on its hardware, that is what the usual idea is.  Well guess again, according to a new study at the Georgia Institute of Technology, the flash drives that are installed in the phones account for the massive dips in the phones performance. The brand and type of microSD card used plays a great role.

A student at the university, Hyojun Kim, who was in-charge of this research  stated that the flash drive technology is not at par with the ever growing mobile technology. This gap (poor handling of random I/O data from the software being used) is the reason why phones are slowing down. Everybody feels annoyed waiting for the apps to load, but what they do not know is that more the wait faster the smartphone battery gets depleted.

“A good chunk of time for users is spent waiting for websites to load … [and for] applications to load,” said Hyojun Kim, a Ph.D. student in the College of Computing at Georgia Tech.

Benchmark Test:

Flash benchmarks
Benchmark testing of smartphone flash memory showed performance varied widely among vendor’s products depending on whether I/O was random or sequential. The smartphone tests involved the use of applications such as WebBench Browser, Facebook, Android Email. Google Maps, App Install, Pulse News Reader, and RLBench SQLite. The flash cards came from Transcend, RiData, SanDisk, Kingston, Wintec, A-Data, Patriot Memory and PNY.
According to their research, they found a possible cure in the form of PRAM. The Phase-change Random Access Memory could be used to increase the efficiency of  random data management. In this the storage space required by the system itself is kept very organized, so the microSD card’s performance increases.
