simple FTL over simulated nand.
NAND flash is simulated as an array with statistics stored for every block.
A simple page based FTL operates over the NAND flash.
Can be used for experimenting with algorithms for FTL.
for input trace generation, in main.cpp, we re-use some code from disksim source(www.pdl.cmu.edu/DiskSim/)
