If you are looking for a budget 2.5-inch SATA SSD you'll quickly find that many are using TLC NAND Flash memory. TLC NAND has come a long way in recent years, but after a number of poorly implemented solutions have come to market it has some enthusiasts avoiding them. The Crucial BX300 series was launched in August 2017 as a budget drive that uses 3D MLC NAND with SLC caching! This should appeal to those that don't want a drive using TLC NAND Flash memory. Say goodbye to the Crucial BX200 with TLC NAND Flash that came out in November 2015!

The Crucial BX300 series is made up of 2.5-inch SATA 6Gb/s SSDs that is available in capacities of 120GB ($59.99), 240GB ($87.99), and 480GB ($144.99). Sequential performance is rated at up to 555MB/s read and 510MB/s write on all three capacities. When it comes to 4K Random IOPS performance all three are rated at 90K write, but differ in read performance. For example the 120GB drive is rated at just 45K IOPS, the 240GB drive is rated at 84K IOPS and the 480GB drive is rated at 95K IOPS. All Crucial BX300 drives come with a 7mm to 9.5mm spacer and a serial number for Acronis True Image HD 2015 software for easy data migration.
