A few months ago we took a look at Crucial's MX300 Solid State Drive. This was the company's first consumer solid state drive to make use of 3D NAND and make them the second company (behind Samsung) to offer a 3D NAND drive to consumers. By using 3D NAND Crucial is able to keep the costs of the drive lower and enable higher capacity drives. When the MX300 was initially launched Crucial only offered a 750GB version, but now the they have filled out the lineup with 275GB, 525GB, 1TB, and 2TB capacities. Today we will be testing the 525GB and 1TB (1050GB) versions of the drive. They offer the same 530 MB/s sequential read and 510 MB/s sequential write speeds as the 750GB. Let's jump in!
