If you want to find a useful answer, you will need to dig much deeper into this matter. What harddisk? A US$ 50 2.5" laptop harddisk ? or a US$ 1000 15.000 rpm SAS server drive ? What SSD ? NAND Flash, NOR Flash, single cell, multi level cell ? As a rule of thumb: Flash doesn't just replace magnetics. To justify the use of flash memory, you will need at least one other reason. And --very important, imho-- a file and operating system that is tuned to flash, while all current mainstream OSs are disk-tuned only :-) -- Kind regards, Gerard Bok
