Given a typical usable life requirement of 5 years, applications that write more than 1x-1.5x drive capacity per day will benefit from higher endurance memory such as SLC or aMLC. Write Amplification is significantly affected by data addressing and variable file sizes. Random addressed data with varying file sizes less than the NAND Flash page/block size is a worst-case scenario. Sequential addressing with files larger than the NAND Flash page/block size aids in minimizing Write Amplification by reducing the number of effective writes to the NAND Flash media.
