Specifications and downloads ↗How to choose
What to check before buying a gaming SSD
Speed matters, but compatibility, capacity, and real use define the right upgrade. Review the essentials.
Read the complete technical guide →Available interface
Confirm whether the computer supports 2.5-inch SATA, M.2 SATA, or M.2 NVMe PCIe. An M.2 connector does not guarantee support for every protocol.
Physical form factor
2.5-inch SATA SSDs use data and power cables. M.2 models connect directly to the motherboard and can have different lengths, such as 2280.
Useful capacity
Account for the operating system, applications, and game library. Keep free space for updates, temporary files, and future growth.
PCIe generation and thermals
For NVMe SSDs, check the PCIe generation and lanes supported. High-performance builds may also need suitable airflow or a compatible heatsink.

Questions about gaming SSDs
Does an SSD increase FPS in games?+
The main gains are usually shorter loading times, faster startup, and better system responsiveness. Average FPS depends mostly on the processor and graphics card, although some games can benefit from faster data access.
Is every M.2 SSD an NVMe drive?+
No. M.2 describes the physical form factor; a drive can use SATA or PCIe/NVMe. Check the motherboard manual and SSD specification.
Does a newer PCIe SSD work in an older slot?+
Many PCIe generations are backward compatible, but performance is limited by the platform. Confirm the generation, available lanes, and manufacturer restrictions.
Does an NVMe SSD need a heatsink?+
It depends on the model, airflow, and workload. Some SSDs and motherboards already include a thermal solution; follow manufacturer guidance and avoid incompatible heatsinks.
