Who it’s best for: gamers building a high-end PC or upgrading a desktop where fans and thermals can be managed. Choose this if you want maximum Gen4 speeds and long-term stamina for demanding titles.
Caution: Thermal throttling can occur under sustained heavy loads unless adequately cooled. Ensure adequate airflow or a heatsink in compact builds.
Samsung SSD 990 PRO 1TB — Gen4 PCIe 4.0
Overview: This 1TB variant prioritizes speed-to-boot with strong random and sequential performance, ideal for smaller builds or users who want Gen4 power without the extra TB storage.
Why it’s chosen: It delivers up to 7450 MB/s read and 6900 MB/s write with impressive IOPS, making load times and large transfers snappy for gaming sessions and content creation workflows.
Who it’s best for: gamers using laptops or compact desktops that support PCIe 4.0 and want a compact, high-speed upgrade. Better for those who don’t need the extra 2TB of space right away.
Caution: While power efficiency improves over older Gen4 drives, it still requires adequate cooling in tight spaces or laptops with limited ventilation.
SIX X7400 NVMe M.2 1TB — Gen4x4
Overview: The SIX X7400 1TB is a Gen4x4 offering high transfer speeds with a focus on gaming workloads and heavy multitasking. It emphasizes raw bandwidth for fast game loads and data-heavy tasks.
Why it’s chosen: Up to 7350 MB/s read speeds help reduce texture streaming times and map loading. It also aims to balance performance with compatibility for desktops, laptops, and PS5 storage expansion.
Who it’s best for: Buyers seeking a high-speed option at a reasonable price, with broad compatibility for PC and console storage expansion.
Caution: The drive’s full potential depends on a capable system assuming PCIe 4.0 support; verify motherboard/PC bios compatibility before purchase.
WD_BLACK P40 1TB — External Gen4 NVMe
Overview: The WD_BLACK P40 is an external NVMe SSD, designed for portable gaming with high read speeds via USB 3.2 Gen2x2 interface. This makes it a strong choice for gamers who want fast game transfers or console compatibility on-the-go.

Buying Guide
What speed do you need for gaming?
Sequential speeds (read/write) influence load times and large file transfers. Random IOPS affect game map loading and texture streaming. For most modern titles, Gen4 drives with 7000–7500 MB/s read speeds deliver noticeable gains; Gen5 drives push even further but require compatible systems.
Internal vs. external storage
Internal M.2 NVMe drives offer the best performance for in-game loading and system responsiveness. External drives excel for portable storage, game libraries, and cross-platform use but may be limited by USB bandwidth.
Capacity considerations
2TB provides ample room for many modern games and updates. If you frequently install large titles or collect media, consider 1TB with a future upgrade plan or 2TB upfront for long-term convenience.
Thermal and power considerations
High-speed NVMe SSDs can throttle under heat. Look for drives with good thermal management, especially in compact desktops or laptops. Heatsinks, airflow, and chassis design impact sustained performance.
Compatibility checklist
- Motherboard or laptop must support PCIe 4.0 or 5.0 for full gains.
- Ensure the M.2 slot is the correct size (2280 is standard).
- Confirm whether the drive is intended for internal or external use.
FAQ
- What is the fastest consumer NVMe SSD for gaming?
PCIe 5.0 drives like the 9100 PRO offer the highest raw speeds, but require compatible systems. - Is PCIe 4.0 enough for gaming today?
Yes, Gen4 drives provide substantial improvements over Gen3 and are widely compatible with current GPUs and CPUs. - Should I buy a 2TB or 1TB drive first?
2TB reduces future upgrades and keeps more games installed, while 1TB is often sufficient if you manage space carefully. - Do external SSDs impact gaming performance like internal ones?
External SSDs are convenient for portability but may show lower real-world game load times due to interface limits. - Can all laptops support PCIe 5.0 drives?
Not all. Check your device specifications and BIOS support before upgrading. - What about thermals for high-speed NVMe drives?
Active cooling or proper airflow helps maintain peak speeds during extended gaming sessions.
