The Drive

The drive conforms to the dimensions set forth by the 2.5" form factor. It is made out of plastic and is only 7 mm thick, which makes it compatible with Intel's Ultrabook specification.


The Crucial BX500 uses the SATA 6 Gbps interface. It is compatible with any older SATA standard, but will, in such a case, work at reduced performance.


You will find the SSD controller and four flash chips on the PCB. As mentioned before, a DRAM chip is not included; more details on that later.


The Silicon Motion SM2258 is a four-channel flash controller; the used XT variant denotes support for DRAM-less SSD designs.


The four 3D TLC flash chips are made by Micron, Crucial's parent company. The NW913 markings decode to MT29F1T08EMHAFJ4. Each chip has a capacity of 1 Tbit (128 GB).
