Magnetic disks (a.k.a. hard drives, HDD) have long been a standard equipment in every computer for long-term storage. With recent advancements of the flash memory technology, solid state disks (SSD) have

gained popularity in their adoption, which is reflected in rapid increase in their market shares in mass storage devices. The development of this technology did not succeed overnight. Many issues have been detected, investigated, and resolved. For this assignment, I would like to refer you to an article entitled “Parameter-Aware I/O Management for Solid State Disks (SSDs)” by Kim, Seo, Jung and Kim, which can be found on IEEE, Trans. on Computers, Vol. 61, No. 5 (May 2012).
