Switching over from the current hard disk drive to a solid-state drive seems an appealing step. But before you take any action in this regard you should realize that SSDs are not free of downsides/disadvantages, such as their steep prices. Even after the dramatic price fall of NAND flash memory, SSD is still deemed expensive. See for example the price of the cheapest 1 TB SSD, which is Samsung 840 Evo, it costs on Amazon by the time of writing $431, that indicates $0.43 per GB, whereas the cost of Western Digital 4TB Black is almost $230, and that indicates $0.0575 per GB, a real vast difference.
