High-capacity gaming SSD

The Samsung 990 PRO w/ Heatsink Gaming Package is an M.2 2280 internal SSD built for consumers who need large, fast storage. It uses V7 V-NAND 3bit MLC memory and a Samsung controller on a PCI-Express Gen 4.0 x4 interface with NVMe 2.0. The 4TB capacity suits modern game libraries and heavy workloads.

Speed headroom and thermal limits

Sequential reads reach up to 7450 MBps and writes up to 6900 MBps, giving wide headroom for loading large assets and sustained transfers. The bundled heatsink helps maintain those speeds under prolonged loads, though the drive will still throttle once its thermal ceiling is reached.

Bundled heatsink impact

The included heatsink attaches directly to the drive to dissipate heat during extended gaming or creative sessions. It changes the thermal profile so the controller can hold peak throughput longer than a bare module would. No extra software or accessories are mentioned in the supplied data.

Questions about this item

Will the 990 PRO 4TB fit and run in a motherboard that only has PCI-Express Gen 3.0 M.2 slots?

The drive uses a PCI-Express Gen 4.0 x4 interface, so it will operate at Gen 3.0 speeds when installed in a Gen 3.0 slot. The M.2 2280 form factor is unchanged, so it physically fits the same slot.

How can I verify the 990 PRO is delivering its rated sequential performance after installation?

Run a benchmark such as CrystalDiskMark and compare the results to the specified maximums of 7450 MBps read and 6900 MBps write. Ensure the motherboard BIOS is set to PCIe Gen 4.0 and NVMe 2.0 is enabled for the slot.

Does the Gaming Package include a mounting screw or any adapters, or do I need to supply them?

The heatsink is pre-attached to the M.2 2280 module. A mounting screw is typically provided by the motherboard manufacturer, not the drive package, so check your board's accessory kit before installation.
