Wbt is achieving NAND speeds. 4ds is achieveing DRAM speeds.
Here is an idea of the difference. Please google the info.


DRAM is the second fastest mode of storage available on your computer, only after the on-board cache(SRAM) integrated on micro-processor die. A modern RAM stick (let's talk about DDR4 at 2133 MHz) is capable of transmitting data at 17064 MB/s or 17 GB/s. The fastest consumer grade SSD that I know of is Samsung 950 Pro; it is capable of about 2500 MB/s or 2.5 GB/s.
The first genration DDR3 RAM was capable of 6.4 GB/s.
