Silicon Power 2TB US75 Nvme PCIe Gen4

Silicon Power 2TB US75 Nvme PCIe Gen4 Review & Specifications

The Silicon Power 2TB US75 Nvme PCIe Gen4 by Silicon Power is a NVMe solid-state drive (SSD) featuring 2000 GB of storage. It is built with TLC 232-layer NAND flash memory and utilizes a Maxiotech MAP1602A controller to manage data access, wear leveling, and overall performance. This drive runs on the PCIe 4.0 x4 interface (up to 16 GB/s) and utilizes the NVMe 1.4 protocol. NVMe 1.4 brought significant updates such as improved power management, persistent memory region support, and native command retry. The SSD comes in a M.2 2280 form factor. PCIe 4.0 is backward compatible with older PCIe slots, but speeds will adjust accordingly.

NVMe SSD Performance

Sequential read and write speeds reach 7000 MB/s and 6500 MB/s respectively, while random read/write performance delivers up to 1000k and 1100k IOPS. The drive offers an endurance rating of 1200 TBW and is backed by a 5-year manufacturer warranty.

This SSD does not include a dedicated external DRAM cache chip. Instead, it relies on a small internal SRAM cache integrated into the controller, typically around 32 MB to 128 MB. Manufacturers may sometimes refer to this SRAM as "DRAM cache," but it is not the same as a discrete DRAM module. Furthermore, because it uses the NVMe interface, the SSD may also support Host Memory Buffer (HMB) — a feature that allocates a small portion of your system’s RAM (usually 64–128 MB) to act as a substitute for DRAM. While this design is cost-effective and suitable for everyday tasks, performance under heavy or sustained random I/O can be lower compared to full-DRAM SSDs. A Dynamic SLC cache is still included to help with write bursts and improve responsiveness.

This SSD module provides strong mid-range performance, achieving 70.3% of the highest score in our benchmark. It delivers excellent responsiveness and load times for a wide variety of tasks, making it ideal for mainstream gaming setups, content creation, software development, and multitasking-oriented workflows. Unless you're working with large-scale real-time data or intensive write-heavy workloads, this level of performance is more than sufficient for demanding users.

Cost-Effectiveness

From a cost-efficiency standpoint, this SSD delivers excellent value at just $54.5 per terabyte. The overall combined performance-to-price ratio, which evaluates both maximum performance and total storage capacity per dollar, is calculated at 90.3%. Based on this metric, the drive is an outstanding choice for users seeking the highest performance and storage return per dollar spent.
