Capacity and audience

The Crucial T705 4TB is an internal SSD built for consumers who need maximum sequential throughput. It uses the PCIe 5.0 x4 interface with NVMe protocol and a 4GB DRAM cache to sustain heavy read and write workloads.

Thermals and power

The drive ships without a heatsink and relies on the motherboard heatsink for cooling. A copper-clad label transfers heat from the controller and NAND to that heatsink, keeping the drive in its performance envelope during sustained loads.

Build integration

The M.2 2280 form factor fits a standard motherboard slot. The drive is validated for Intel Core 13-14th Gen and AMD Ryzen 7000 platforms and uses Micron 232-layer TLC NAND. One month of Adobe Creative Cloud All-Apps is included with purchase and registration.

Questions about this item

Does this drive need a separate heatsink?

The drive ships without a heatsink and is designed to use the motherboard M.2 heatsink; its copper-clad label transfers heat to that heatsink for sustained performance.

Will it work with my Intel Core 13th or 14th Gen or AMD Ryzen 7000 system?

Yes, the drive is built with Micron 232-layer TLC NAND and validated for Intel Core 13-14th Gen and AMD Ryzen 7000 platforms running PCIe 5.0.

What speeds can I expect in real use?

Sequential reads up to 14,100 MB/s and writes up to 12,600 MB/s; random reads up to 1,500,000 IOPS and writes up to 1,800,000 IOPS.
