The Drive

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


PCI-Express 5.0 x4 is used as the host interface to the rest of the system, which doubles the theoretical bandwidth compared to PCIe 4.0 x4.


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


Samsung has installed this small heat spreader foil on the back of the drive.


It has a thin cooper core which helps a little bit, but isn't powerful enough to compete with a dedicated heatsink.

Chip Component Analysis

The Samsung Presto (S4LY027) controller is built on a 5 nm process at Samsung, with a 5-core Arm Cortex-R8 architecture. It features eight flash channels with support for PCI-Express 5.0 x4 and NVMe 2.0.


The two flash chips are Samsung 236-layer 3D TLC NAND. Each chip has a capacity of 1 TB.


The DRAM cache is a 2 GB LPDDR4X-4266 chip.
