Silicon Power 2TB NVMe M.2 PCIe Gen3x4 2280 SSD Solid State Drive Review & Specifications

The Silicon Power 2TB NVMe M.2 PCIe Gen3x4 2280 SSD Solid State Drive by Silicon Power is a NVMe solid-state drive (SSD) featuring 2000 GB of storage. It is built with TLC Intel 64L NAND flash memory and utilizes a Silicon Motion SM2263XT controller to manage data access, wear leveling, and overall performance. Utilizing the older PCIe 3.0 x4 interface, this model offers a theoretical maximum throughput of up to 8 GB/s. It is based on the NVMe 1.3 standard, which provided improved error logging, sanitize commands, and host memory buffer (HMB) support. Packaged in the M.2 2280 form factor, it remains a cost-effective and widely compatible solution for general-purpose computing.

NVMe SSD Performance

Sequential read and write speeds reach 2200 MB/s and 1600 MB/s respectively, while random read/write performance delivers up to 240k and 250k 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 offers entry-level performance in our synthetic benchmark, scoring 57.0% relative to the fastest NVMe SSDs in our database. However, this classification doesn't always reflect real-world capability. Many drives in this range — especially those with DRAM cache, and even some newer, efficient DRAM-less models — can still deliver responsive performance in general computing, gaming, light creative work, and casual development environments. Unless your workload involves large file transfers or sustained heavy I/O, this level of performance is more than adequate.

Cost-Effectiveness

From a cost-efficiency standpoint, this SSD delivers excellent value at just $49.0 per terabyte. The overall combined performance-to-price ratio, which evaluates both maximum performance and total storage capacity per dollar, is calculated at 81.4%. Based on this metric, the drive is an outstanding choice for users seeking the highest performance and storage return per dollar spent.
