SanDisk 256GB X210 Internals
The SanDisk X210 comes in a 7.5mm z-height metal casing. This slim 2.5" form factor is well suited for slim applications.
The case comes apart easily once four screws are removed. The top portion of the case is actually made of a metal alloy and the bottom consists of plastic. The metal half has thermal pads that wick heat away from the NAND, DRAM and Marvell 9187 controller. This extends the life of the components, and helps cool the SSD in high heat environments.
The bottom of the PCB faces into the plastic portion of the case, and is devoid of components.
The top of the PCB holds eight of the BGA-mounted 32GB ABL NAND packages, along with the controller and DRAM.
