Samsung unveils the world’s highest capacity consumer SSD

Samsung today announced what it claims is the highest capacity consumer solid state drive, a 4TB member of its 850 EVO line, which will retail for $1,499 or about 36 cents per gigabyte of capacity.

The new 850 EVO SSD uses Samsung's 48-layer high V-NAND technology, which stacks flash memory cells one atop another like microscopic skyscrapers and stores three bits per cell.

Samsung then crammed the 4TB of capacity into a 2.5-in. SSD form factor only 7mm thick, which is small enough to fit into ultra-slim notebooks. Previously, Samsung's 2TB EVO SSD was its highest capacity flash drive.
