Crucial T705 w/ Heatsink - M.2 PCIe Gen5 NVMe SSD - 4TB

The Crucial T705 with heatsink bundles the same T705 drive (Phison E26, Micron 232-layer TLC, DRAM cache) with an aluminum heatsink for PS5 compatibility and desktop systems without M.2 cooling.

Same Drive, Heatsink Included

Specs are identical to the bare T705: up to 14,500/12,700 MB/s sequential read/write on the 2TB, with 1,550K/1,800K IOPS random I/O. The heatsink adds thermal protection during sustained transfers, which Gen5 drives genuinely need. The Phison E26 will throttle without adequate cooling.

PS5 and Desktop Use

The heatsink is sized to fit the PS5's M.2 expansion bay. For desktop builds, it serves as a fallback if your motherboard's M.2 slot lacks its own heatsink or if the included heatsink is too thin to handle Gen5 thermals effectively.

Endurance

600 TBW (1TB), 1,200 TBW (2TB), 2,400 TBW (4TB). Five-year warranty.

Best for: PS5 storage expansion where you want near-maximum Gen5 performance. Desktop builds with exposed M.2 slots. The 2TB model is the sweet spot for price-to-performance.

Avoid if: Your motherboard has a quality M.2 heatsink already. The bare T705 is cheaper and performs identically with proper cooling.
