Crucial P310 4TB NVMe SSD

The Crucial P310 is a 4TB internal solid-state drive built for consumer PCs that need fast, high-capacity storage. It uses the M.2 2280 form factor and connects through a PCIe 4.0 x4 interface with NVMe 2.0 protocol. The drive employs Micron 3D NAND technology and operates without a DRAM cache, relying on Host Memory Buffer instead. It fits standard M.2 slots in modern desktops and laptops.

4TB capacity with Gen4 speeds

Sequential reads reach up to 7100 MBps and writes up to 6000 MBps, providing ample throughput for large game libraries, media projects and heavy multitasking. The 4TB capacity offers generous headroom for operating systems, applications and bulky files without constant space management. Performance scales with PCIe 4.0 platforms; on older PCIe 3.0 systems the drive will run at lower speeds limited by the bus. Sustained write workloads may see reduced speeds once the SLC cache fills.

DRAMless design with HMB

This SSD has no dedicated DRAM cache and uses Host Memory Buffer to manage mapping tables. That design keeps costs down while still delivering strong Gen4 performance for most consumer workloads. Systems must support HMB for the feature to function; otherwise the controller relies solely on internal resources. Buyers building a DRAM-sensitive workstation or enterprise array should verify this constraint before choosing the P310.

Questions about this item

Will this 4 TB M.2 2280 drive fit my laptop or desktop slot?

The drive uses the standard M.2 2280 form factor, so it fits any M.2 slot that accepts 80 mm length modules. Check your device manual to confirm the slot supports PCIe 4.0 x4 NVMe and has physical clearance for a single-sided board.

Does the lack of a DRAM cache and heatsink affect sustained write performance?

The drive uses Host Memory Buffer instead of onboard DRAM and has no heatsink. Sequential write reaches 6000 MB/s, but prolonged heavy writes may throttle sooner in a poorly ventilated slot. Adding a motherboard heatsink helps maintain peak speeds.

What PCIe generation do I need to reach the advertised 7100 MB/s read speed?

A PCIe 4.0 x4 NVMe 2.0 connection is required for the full 7100 MB/s read and 6000 MB/s write. The drive works in PCIe 3.0 slots but will run at the lower generation's speed limits.
