The Drive

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


Like most recent SSDs, the ADATA SU900 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. A DRAM chip is also present; it provides the SSD controller with RAM and can also buffer incoming writes.


The Silicon Motion SM2258 is a four-channel SSD controller with support for Opal/TCG, which ADATA chose not to enable on the SU900, though. The SM2258H variant seems to be a new revision I haven't seen on any other drives yet.


The eight MLC flash chips are produced by IMFT (Intel/Micron) and are built on a 16 nanometer 3D NAND process. ADATA chose to rebrand them with their own company logo.
