Samsung 990 PRO 4TB NVMe SSD

This Samsung 990 PRO MZ-V9P4T0CW is a 4TB internal solid-state drive built for consumer desktops and workstations that demand high sequential throughput. It uses Samsung V-NAND TLC memory, a PCI-Express 4.0 x4 interface and the NVMe 2.0 protocol with a 4GB DRAM cache. Sequential reads reach up to 7450 MBps and writes up to 6900 MBps. The integrated heatsink and RGB lighting help manage thermals during sustained workloads.

Compatibility check before ordering

Verify that your motherboard or laptop provides an M.2 2280 slot wired for PCI-Express 4.0 x4 and NVMe 2.0 signalling. Confirm the physical clearance for a drive with an attached heatsink, as the added height may interfere with nearby components or case panels. Ensure the system BIOS and operating system support NVMe boot and the DirectStorage API for the advertised gaming-load improvements. The drive is also listed as compatible with PlayStation 5 expansion slots.

Bundled heatsink and software impact

The pre-fitted heatsink is designed to prevent thermal throttling so the controller can sustain peak sequential speeds during long sessions. Samsung notes up to 50 percent better power efficiency versus the 980 PRO thanks to the 8nm controller, and up to 65 percent higher random read and write IOPS at 1400k and 1550k respectively. DirectStorage optimisation reduces game asset streaming latency when the OS and title both support the API.

Questions about this item

Does the MZ-V9P4T0CW include the heatsink or must I buy one separately?

The drive ships with a slim heatsink already attached, so no separate cooler is required.

Why choose the 4TB 990 PRO over a smaller capacity in the same series?

The 4TB model delivers the same 7,450 MB/s sequential read and 6,900 MB/s write speeds while providing four terabytes of V-NAND TLC storage for large game libraries and workloads.

What does the 7,450 MB/s sequential read figure mean for actual gaming loads?

It represents the PCIe 4.0 x4 interface limit, enabling faster level streaming and reduced texture pop-in when the system uses DirectStorage API.
