Poor NAND Flash Performance Leads To Sluggish Phones

According to a recent Georgia Institute of Technology and NEC Corp. study, the reason behind smartphones acting sluggish is not always — as pointed out by some — because of the processor and network connectivity but very much due to lazy chips used for internal storage.

There were several top selling Android smartphones tested in the research, all with 16GB flash memory. The study found that “performance over WiFi declined an average of 100 percent to 300 percent across mobile applications”, going as low as 2000 percent in some tests.

The inclusion of poor NAND chips can not only degrade device-wide performance and operation but it can also cause battery drain, according to the study. While dual-core (and even single-core) processors can easily cope with mobile applications (and so can wireless network performance), it’s the memory which often falls short.

“Apart from the benefits of selecting a good flash card, there are some fundamental ways we’re using storage in a bad way”, said Hyojun Kim, Georgia Tech College of Computing Ph.D. student. The biggest problem of flash memory is the performance loss while random accessing and writing. To read more details about the study head over to the source link below.
