Crucial 480GB BX200 TLC SSD Review

Storage/SSD by stefan @ 2016-04-02

As we have seen with the Trion 100, Crucial is also settling into the affordable and high-capacity SSD market with their BX200 by incorporating Micron 16nm 128Gbit TLC NAND, a Silicon Motion SM2256 and also DRAM cache which varies in size depending on the total capacity of the drive. When writing up to 6GB files to the drive, the SLC cache takes up the effort and we are able to see good read/write speeds all over the board; however, if we are planning on working with very large files most of the time, the cache will fill up quite quickly and we will be forced to perform read/write operations directly to the TLC NAND, which is considerably slower.

A Closer Look Contd.

Also here we do get the SATA Data/Power ports:

As we have seen with the previous model, BX200 comes with a screw-less design, which means that the top and the bottom parts snap together and it is quite difficult to take them apart:

While the bottom area of the 480GB model is blank, on the front we will get to see eight NAND chips, along with the DDR3 memory buffer and also the controller:

Here is a close-up of the Micron 16nm TLC NAND:

As buffer, we do get a D9SDD 512MB DDR3 Micron memory chip:

The main controller is different from the one found on the BX100 so we are dealing with a Silicon Motion SM2256, which does support Active Garbage Collection but also TRIM. For the 480GB model, Crucial does also use SLC cache in a quantity of 6GB which speeds up the initial transfer speeds until this one fills up:
