Samsung 990 EVO Plus SSD 4TB - High-Speed PCIe Gen4 Storage

In this review of the Samsung 990 EVO Plus SSD 4TB, the bottom line is simple: this drive is for users who need very large, fast internal storage for demanding workflows and modern gaming consoles. The 990 EVO Plus stands out because it pairs a true 4TB capacity with sequential read speeds up to 7,250 MB/s and Intelligent TurboWrite2.0 for sustained large-file performance, making it a practical upgrade for creators, PC enthusiasts, and those migrating large OS installs. It reviews well for compatibility and real-world speed without excessive power draw.

Key Features

• Groundbreaking speed: Sequential read/write performance up to 7,250/6,300 MB/s speeds large transfers and load times for heavy projects and games.
• Large 4TB capacity: A true 4TB drive lets users store many games, video projects, or multiple OS images on a single M.2 module.
• Intelligent TurboWrite2.0: Enhanced caching helps maintain higher throughput on large-file workloads compared with basic TLC implementations.
• Thermal efficiency: A nickel-coated controller reduces power draw and improves thermal control so the drive stays cool under sustained use.
• Modern interface support: Compatible with PCIe 4.0 x4 and PCIe 5.0 x2, offering broad motherboard and future-proofed bandwidth options.
• Ongoing software support: Samsung Magician keeps firmware current and provides drive monitoring plus optional encryption features.

Who It's For

The 990 EVO Plus 4TB is aimed at creative professionals, power users, and gamers who need both very high sequential speeds and a large single-drive capacity. Video editors working with large media files, software developers keeping many virtual machines or disk images, and anyone upgrading storage for a PS5-compatible slot will appreciate the combination of speed and space.

Users who primarily need light storage for documents or casual web use should look for lower-capacity, lower-cost alternatives. Also, to extract the full performance benefit you should confirm your system supports PCIe 4.0 or newer; older PCIe gen slots will limit peak throughput.

Pros & Cons

Pros

• Very fast sequential read/write rates accelerate large transfers and load times.
• Large 4TB capacity removes the need for immediate external storage for many users.
• Nickel-coated controller improves thermal control and power efficiency during long sessions.
• Samsung Magician provides firmware updates and drive health monitoring for long-term reliability.

Cons

• To reach top speeds requires a PCIe 4.0 or 5.0-capable host; older systems will see reduced throughput.
• High-capacity NVMe drives are more expensive than lower-capacity alternatives, which may be overkill for casual users.

Frequently Asked Questions

Will this work in a PS5?
Yes, customers report PS5 compatibility when the console or slot supports the required M.2 size and cooling; confirm physical space and thermal requirements before installation.

Do I need PCIe 4.0 to see the speed benefits?
You will get higher bandwidth with PCIe 4.0 x4 or PCIe 5.0 x2; older PCIe generations will limit the peak sequential speeds.

How do I keep the drive firmware up to date?
Use Samsung Magician software to check for firmware updates, enable drive health monitoring, and configure optional encryption settings.
