How to Choose

Sequential Read/Write Speeds

Read speed determines how fast games and applications launch. Write speed matters when transferring large files like video projects. Most users are bottlenecked by random I/O in everyday use, not sequential throughput. For gaming, read speeds above 5000 MB/s offer diminishing returns; a 7300 MB/s drive won't launch Windows noticeably faster than a 6000 MB/s one. Focus on write speed only if you regularly move big datasets.

Interface Generation

PCIe 4.0 is the sweet spot for 2026: it saturates current game load times and is backward compatible with PCIe 3.0 slots (though at reduced speeds). PCIe 5.0 doubles bandwidth but demands a compatible motherboard and active cooling to avoid throttling. If your system lacks Gen5 support, a Gen4 drive is the most cost-effective choice. Only invest in Gen5 if you plan to upgrade your platform and work with AI or 8K video.

Capacity

Modern AAA games exceed 100 GB each, so a 1TB drive fills quickly. For a boot drive plus a few titles, 1TB suffices. For a game library without constant uninstalling, 2TB is the practical minimum. Higher capacities cost more per GB but reduce the hassle of managing space. If your budget allows, stepping up to 2TB on a reliable Gen4 drive is a better long-term investment than a smaller Gen5 drive.

Endurance & Warranty

Endurance is measured in TBW (terabytes written). A 1TB drive rated for 600 TBW can handle writing 1TB daily for over 1.5 years. For a boot drive with light use, even 300 TBW is fine. For heavy write workloads (video editing, databases), look for 600+ TBW. Warranty length often correlates with expected lifespan: 5-year warranties are standard on premium drives, while budget models may offer only 3 years. Shorter warranties and lower TBW increase the risk of premature failure.

Thermal Management

NVMe SSDs throttle performance when they exceed their temperature limits, typically around 80°C. Gen4 drives often produce enough heat to benefit from a heatsink, especially in laptops or compact cases with limited airflow. Some drives (like the WD_BLACK SN7100) are designed to run cool without one, while others (like the Samsung 9100 PRO) require active cooling. In a desktop, a motherboard heatsink is usually sufficient. In a handheld or slim laptop, prioritize a low-heat drive to avoid random slowdowns during long sessions.
