Packaging
The Drive
The drive conforms to the dimensions set forth by the 2.5" form factor. It is made out of plastic and only 7 mm thick, which makes it compatible with Intel's Ultrabook specification.
The Team Group Vulcan Z uses the SATA 6 Gbps interface. It is compatible with any older SATA standard, but will in such a case work at reduced performance.
On the PCB, you'll find the controller and two flash chips, a DRAM cache chip is not available.
Chip Component Analysis
The Silicon Motion SM2259XT G is an older SATA SSD controller. It supports four flash channels and is optimized for DRAM-less operation.
The two flash chips are Hynix 128-layer 3D TLC NAND. Each chip has a capacity of 1 TB.
