Gen5 performance with a factory-installed thermal solution
The Crucial T705 4TB with heatsink combines Micron 232-layer TLC NAND with an aluminium-and-copper heatsink designed to dissipate heat under suitable airflow. It targets compatible PCIe Gen5 systems for gaming, content creation and other heavy storage workloads.
Exact 4TB performance
This capacity is rated at 14,100MB/s read and 12,600MB/s write rather than the higher 2TB series maximum.
High random throughput
The 4TB profile reaches up to 1,500K random-read and 1,800K random-write IOPS.
Micron 232-layer TLC NAND
The T705 uses Micron TLC NAND engineered for Crucial's Gen5 performance range.
DirectStorage support
Microsoft DirectStorage is supported when the rest of the system and software meet its requirements.
Backward-compatible interface
The drive can operate in compatible PCIe Gen4 and Gen3 systems at the lower interface speed.
Premium passive heatsink
The integrated aluminium-and-copper heatsink is designed for passive heat dissipation with proper system airflow.
Who is the Crucial T705 4TB with heatsink best for?
A strong choice for
- High-end compatible PCIe Gen5 desktops
- Large game libraries and DirectStorage-capable systems
- Video editing and 3D rendering
- Heavy local creative workloads
- Builds needing a pre-installed SSD heatsink
Consider another model if you need
- Your system lacks an M.2 PCIe NVMe slot
- Your workload does not benefit from Gen5 performance
- Your motherboard clearance cannot accept the 0.83-inch heatsink height
- You need lower power or heat output
