Silicon Power US70 1TB M.2 PCIe Gen4x4 SSD

Race into the Future: PCIe 4.0

A Closer Look

Silicon Power’s US70 comes in a small black box similar to some of their other models. Basic specs can be found on the back in several languages. Gold accents differentiate this PCIe gen 4 drive from the UD70 PCIe Gen 3 drive we tested recently.

The US70 is a standard 2280 sized M.2 M-Key drive. It comes with a blue PCB with a sticker covering most of the front.

On the back, there are two DRAM modules as well as a NAND flash module. The DRAM cache is comprised of a pair of SKHynix 512MB DDR4-2400 C17 memory modules.

On the front, two 3D NAND flash modules make up half of the 1TB of capacity. We weren’t able to find a spec sheet for these specific modules.

Closer to the connector we find a Phison E16 controller which was the world’s first consumer PCIe 4.0 SSD Controller and supports up to 8 channels of TLC or QLC storage. Half of the DRAM Cache sits right next to the Phison controller.
