Instead of a box, the US75 comes packaged in a cardboard blister pack.  The packaging advertises some of the drive's key features including its 1TB capacity, PCIe Gen 4x4 interface, support for NVMe 2.0, maximum read and write speeds and 5 year warranty.

Physical Features:

The US75 uses the 2280 form factor for M.2 (NGFF) SSDs. It measures 22 x 80 x 3.6 mm and weighs in at 8g. The drive also has an "M key" edge connector which provides PCIe SSDs with up to 4x lanes of bandwidth.

The US75 uses Maxio Technology's MAP1602 controller chip. This DRAM-less, PCIe Gen 4x4 NVMe 2.0 controller is equipped with a quad-core ARM Cortex R5 CPU and has 4 NAND channels with four chip enables (CE) per channel. The MAP1602 also offers support for 3D TLC/QLC NAND flash as well as Maxio's Agile ECC error correction technology.

For the 1TB version of the US75, Silicon Power opted to use YMTC's 232-layer 3D TLC NAND flash. Looking at the picture above, you can see four 256GB NAND flash packages on the top of the PCB. There is also no DRAM cache chip as the US75's controller takes full advantage of NVMe's Host Memory Buffer feature by using a small portion of the computer's memory to cache the mapping tables.
