Crucial T705 4TB PCIe Gen5 NVMe Review & Specifications

The Crucial T705 4TB PCIe Gen5 NVMe by Crucial is a NVMe solid-state drive (SSD) featuring 4000 GB of storage. It is built with TLC 232-layer NAND flash memory and utilizes a Phison E26 controller to manage data access, wear leveling, and overall performance. This model leverages the cutting-edge PCIe 5.0 x4 interface, delivering a theoretical maximum bandwidth of up to 32 GB/s. It also complies with the modern NVMe 2.0 specification, which introduces modular architecture, improved command sets, and support for Zoned Namespaces. The drive is available in a M.2 2280 form factor. Note that optimal performance requires a motherboard with PCIe 5.0 support; otherwise, the SSD will operate at the maximum speed allowed by your system configuration.

NVMe SSD Performance

Sequential read and write speeds reach 14100 MB/s and 12600 MB/s respectively, while random read/write performance delivers up to 1500k and 1800k IOPS. The drive offers an endurance rating of 2400 TBW and is backed by a 5-year manufacturer warranty.

This SSD includes a dedicated 4096 MB DRAM cache module running at 4266 MHz. This discrete DRAM chip serves as a high-speed buffer between the controller and NAND flash, significantly reducing latency and improving random read/write performance. DRAM allows the controller to store the Flash Translation Layer (FTL), which is essential for efficient address mapping and wear leveling. Combined with a Dynamic SLC write cache, it offers excellent burst speeds and consistent performance under heavy workloads.

This SSD module offers high-end performance, achieving 89.4% of the top score in our synthetic benchmark, relative to the fastest NVMe SSD tested. It is an excellent choice for enthusiast gaming systems, professional creative suites, and data-heavy workloads such as compiling, virtualization, and large-scale file transfers.

Cost-Effectiveness

From a cost-per-storage perspective, this SSD provides moderate value at $97.3 per terabyte. The overall combined performance-to-price ratio, which evaluates both maximum performance and total storage capacity per dollar, is calculated at 64.4%. Based on this metric, the drive is a less favorable value in this category. However, with a high raw performance rating of 89.4%, it may still appeal to users who prioritize speed and responsiveness over cost or capacity. For budget-conscious users, more balanced alternatives may be preferable.
