TEAMGROUP MP44S SSD 1TB SLC Cache Gen 4x4 M.2 2230 PCIe 4.0 Review & Specifications

The TEAMGROUP MP44S SSD 1TB SLC Cache Gen 4x4 M.2 2230 PCIe 4.0 by TeamGroup is a NVMe solid-state drive (SSD) featuring 1000 GB of storage. It is built with QLC 176-layer NAND flash memory and utilizes a Phison E21T 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 2230 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 5000 MB/s and 3500 MB/s respectively, while random read/write performance delivers up to 480k and 500k IOPS. The drive offers an endurance rating of 250 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 62.2% 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 $70.0 per terabyte. The overall combined performance-to-price ratio, which evaluates both maximum performance and total storage capacity per dollar, is calculated at 62.2%. Based on this metric, the drive is a less favorable value in this category. Considering its performance rating of 62.2%, other SSDs at similar or lower prices may deliver better overall performance and capacity per dollar, making this drive less competitive.
