Do I need a heatsink for the Crucial T705?

Yes, in practice. The drive ships bare, and Crucial says to use your motherboard's heatsink or an aftermarket one with proper airflow. Without it, sustained writes will throttle.

Will the T705 work in my motherboard?

Only if you have an M.2 slot wired for PCIe Gen5 x4, such as on Intel 13th/14th Gen or AMD Ryzen 7000 boards. It fits a standard M.2 2280 slot, but on a Gen4 slot it runs at Gen4 speeds.

How fast is it really?

Crucial rates it at up to 14,100 MB/s sequential read and 12,600 MB/s write, with 1.5M random read and 1.8M random write IOPS. Real-world numbers depend on cooling and workload.

Is the 4TB version worth the price over the 2TB?

If you want one drive for a large game and project library, the 4TB saves slots and carries a 2,400 TBW endurance rating. If you rarely fill 2TB, the smaller model costs less per purchase.

Is it good for PS5 or a laptop?

No for PS5, which uses its own Gen4 drive spec. In laptops, check clearance for a heatsink and expect the drive's power draw and heat to be a concern.

The bare M.2 2280 SSD. No heatsink or mounting screws are included, so plan for your motherboard's cover or a separate cooler.

Our take on the Crucial T705 PCIe Gen5 NVMe SSD 4TB

The Crucial T705 is a 4TB PCIe Gen5 x4 NVMe M.2 2280 SSD built on Micron TLC NAND, rated up to 14,100 MB/s sequential read and 12,600 MB/s write. It targets Gen5 platforms (Intel 13th/14th Gen, AMD Ryzen 7000) and supports Microsoft DirectStorage. It ships without a heatsink, so it needs your motherboard's cover or an aftermarket cooler with airflow. At $629.99 at Walmart as of November 8, 2026, it sits at the top of the 4TB Gen5 price band rather than at a discount.

What reviewers say

Owners of Gen5 drives in this class consistently report very fast real-world load and transfer times, but heat is the recurring complaint. Most say the drive needs a substantial heatsink and airflow to hold peak speeds.

What people mention

SpeedPraisedBuyers report transfers and loads far quicker than Gen4 drives in day-to-day use.
HeatCriticisedOwners say the drive gets hot and can throttle during long writes without a large heatsink.
HeatsinkMixedSome are fine using a motherboard cover; others say an aftermarket cooler is effectively required.
ValueCriticisedCommenters note the price per terabyte is steep next to Gen4 drives of the same capacity.
CapacityPraisedA single 4TB drive replacing several smaller ones is a common reason buyers pick it.
