High-performance PCIe 4.0 storage in the 4TB heatsink configuration
The Samsung 990 PRO 4TB MZ-V9P4T0CW combines Samsung V-NAND TLC, an in-house controller and 4GB LPDDR4 cache for high-performance client storage. This exact capacity has its own random-read, power and endurance profile, while the pre-installed heatsink provides the official thermal configuration.
PCIe 4.0 x4
The drive uses PCIe 4.0 x4 with NVMe 2.0 and is backwards compatible with PCIe 3.0.
7,450/6,900MB/s
Samsung rates every listed 990 PRO capacity up to 7,450MB/s sequential read and 6,900MB/s sequential write.
1,600K IOPS/1,550K IOPS
This 4TB profile is rated up to 1,600K IOPS random read and 1,550K random write IOPS at QD32.
4GB LPDDR4 cache
The exact 4TB model includes 4GB of Samsung-specified LPDDR4 DRAM cache memory.
Factory-fitted heatsink
The integrated heatsink must remain fitted, and the host needs clearance for the published maximum dimensions.
Security and warranty
AES 256-bit, TCG Opal 2.0 and IEEE1667 support accompany a five-year limited or 2,400TBW warranty, whichever comes first.
Who is the Samsung 990 PRO 4TB MZ-V9P4T0CW best for?
A strong choice for
- Compatible high-performance client PCs
- Gaming and creative workflows
- Systems with a compatible M.2 2280 PCIe 4.0 slot
- Samsung Magician-supported storage management
- 4TB buyers needing the integrated-heatsink configuration
Consider another model if you need
- Your system lacks an M.2 2280 PCIe slot
- Your host cannot accommodate the 80.15 × 25 × 8.88mm dimensions
- Your platform cannot provide sufficient airflow or cooling
- You require endurance above 2,400TBW
- You need an enterprise or data-centre SSD
