The Drive

The drive uses the M.2 2280 form factor, which makes it 22 mm wide and 80 mm long.


Like most M.2 NVMe SSDs, the Sabrent Rocket connects to the host system over a PCI-Express 3.0 x4 interface.


Sabrent's sticker doubles up as a heatspreader due to it having copper foil underneath.


On the PCB, you'll find the controller, four flash chips, and a DRAM chip.

Chip Component Analysis

The flash controller is made by Phison and their latest model with support for QLC and PCI-Express 3.0 x4. On the Rocket (without the "Q") it runs in TLC mode, though. It uses eight flash channels and is produced on a 28 nm process at TSMC Taiwan. The main difference to the E12 without the "S" is that the E12S is physically smaller, works with half the DRAM capacity of the E12, and uses a metal case, which helps with thermals.


The four TLC flash chips are made by Micron, built using 64-layers on a 3D NAND production process.


A Kingston DDR3-1866 chip provides 512 MB of fast DRAM storage for the controller to store the mapping tables.
