While the PCI-Express interface is currently the way forward for performance SSD drives, 3D NAND technology holds the key to SSD capacities never even dreamed of before; Samsung's 16TB PM1633a being the perfect example of this. 3D NAND can help achieve these huge capacities because its fabrication process allows for the creation of much denser NAND chips than the standard 2D Planar process.

Samsung has had quite a head start in offering drives that use 3D NAND into the consumer marketplace but other drive manufacturers are slowly but surely entering the fray. Crucial have thrown their hat into the ring with the MX300 750GB Limited Edition.
