Understanding 4TB SSD Technology

A 4TB SSD is a high-capacity storage device using flash memory instead of spinning disks. With 4 terabytes (4,000GB) of space, you can store approximately 800 HD movies, 1.3 million photos, or 100+ modern games.

These drives connect via different interfaces: PCIe for internal drives (offering the fastest speeds), SATA for older systems, and USB for external storage. The technology has matured significantly in 2025, making large capacity SSDs more affordable than ever.

How to Choose the Best 4TB SSD?

Choosing the right 4TB SSD doesn’t have to be complicated. Based on my testing experience, here are the key factors to consider:

Solving for Speed Requirements: Look at Sequential and Random Performance

Sequential speeds (measured in MB/s) matter for large file transfers. If you’re editing 4K video or moving large datasets, look for drives with 7,000+ MB/s read speeds. For gaming and general use, random IOPS performance is actually more important – this affects how quickly games load and how snappy your system feels.

Solving for Compatibility: Match the Interface to Your System

Not all SSDs work with all systems. If you have an older computer without M.2 slots, you’ll need a SATA SSD like the Samsung 870 EVO. For modern gaming PCs, PCIe 4.0 NVMe drives like the Samsung 990 PRO offer the best performance. Check your motherboard specs before buying to ensure compatibility.

For more detailed information on SSD form factors and compatibility, check our comprehensive guide.

Solving for Endurance Needs: Check TBW Ratings

Endurance is measured in TBW (terabytes written). If you’re just gaming and browsing, even 300 TBW is plenty. Content creators writing terabytes daily should look for 1,000+ TBW. The Samsung 870 EVO offers an incredible 2,400 TBW, while many NVMe drives range from 600-1,200 TBW.

Solving for Thermal Management: Heatsinks vs Bare Drives

High-performance NVMe drives can get hot. If you’re doing sustained writes (video editing, file transfers), consider a drive with a heatsink or ensure your motherboard has M.2 cooling. Gamers typically don’t need heatsinks as gaming involves more reading than writing.

Solving for Budget Constraints: Price Per GB Analysis

Currently, PCIe 4.0 drives cost about 6-8 cents per GB, while SATA drives are around 5-7 cents. External portable drives command a premium at 7-10 cents per GB due to their convenience. The WD_BLACK SN7100 offers excellent value at just under 6 cents per GB with flagship-level performance.

Use our price per GB calculator to compare different storage options and find the best value.

Solving for Portability Needs: Internal vs External

If you need to move data between computers, external drives are the obvious choice. The Samsung T7 offers excellent performance in a tiny package. For maximum portability with protection, consider the rugged T7 Shield. Internal drives are faster and cheaper per GB but tied to one computer.

If you encounter any issues during installation, our SSD troubleshooting guide can help fix common problems.
