Solid-state drives (SSDs) have revolutionized storage technology, offering significantly faster speeds and improved performance compared to traditional hard disk drives. As we move into 2024, the latest PCIe Gen 5 SSDs are making headlines with their blazing-fast speeds. However, for most users, PCIe Gen 4 SSDs still offer the best balance of performance and value. In this comprehensive guide, we’ll explore the differences between Gen 5 and Gen 4 SSDs, and why Gen 4 remains the smarter choice for most consumers.
Understanding PCIe Generations
Before diving into the specifics of Gen 5 and Gen 4 SSDs, it’s essential to understand the progression of PCIe (Peripheral Component Interconnect Express) technology:
- PCIe Gen 3: Introduced in 2010, offering speeds up to 8 GT/s per lane
- PCIe Gen 4: Launched in 2017, doubling speeds to 16 GT/s per lane
- PCIe Gen 5: Released in 2019, again doubling speeds to 32 GT/s per lane
Each new generation effectively doubles the bandwidth of its predecessor, allowing for faster data transfer rates and improved overall performance.
PCIe Gen 5 SSDs: The Latest and Greatest
PCIe Gen 5 SSDs represent the cutting edge of storage technology, offering theoretical speeds up to 13,000 MB/s for sequential reads and 12,000 MB/s for sequential writes. These drives leverage the increased bandwidth of the PCIe 5.0 interface to deliver unprecedented performance.
Advantages of Gen 5 SSDs:
- Blazing-fast speeds: Gen 5 SSDs offer the highest theoretical speeds available in consumer storage.
- Future-proofing: As software and games become more demanding, Gen 5 SSDs will be well-equipped to handle future requirements.
- Improved multitasking: The increased bandwidth allows for better performance when running multiple intensive tasks simultaneously.
Disadvantages of Gen 5 SSDs:
- High cost: As the newest technology, Gen 5 SSDs command a significant price premium.
- Limited availability: Few Gen 5 SSDs are currently on the market, limiting options for consumers.
- Compatibility issues: Not all systems support PCIe 5.0, requiring newer motherboards and processors.
- Increased power consumption and heat generation: The higher speeds come at the cost of increased power draw and heat output.
PCIe Gen 4 SSDs: The Sweet Spot for Performance and Value
While Gen 5 SSDs offer impressive theoretical speeds, PCIe Gen 4 drives continue to provide excellent performance at a more reasonable price point. With sequential read speeds up to 7,000 MB/s and write speeds up to 6,000 MB/s, Gen 4 SSDs offer plenty of speed for most users.

- Better value: Gen 4 SSDs offer a superior price-to-performance ratio compared to Gen 5 drives.
- Broader compatibility: Many current systems support PCIe 4.0, making adoption easier.
- Lower power consumption and heat generation: Gen 4 SSDs typically run cooler and consume less power than their Gen 5 counterparts.
Disadvantages of Gen 4 SSDs:
- Not the absolute fastest: For users who demand the highest possible speeds, Gen 4 SSDs fall short of Gen 5 performance.
- May become outdated sooner: As technology progresses, Gen 4 SSDs may become obsolete faster than Gen 5 drives.
Why Gen 4 SSDs Remain the Better Choice for Most Users
Despite the impressive specifications of Gen 5 SSDs, there are several compelling reasons why Gen 4 drives continue to be the smarter choice for most consumers in 2024:
1. Price-to-Performance Ratio
Gen 4 SSDs offer an excellent balance between cost and performance. While Gen 5 drives may boast higher theoretical speeds, the real-world performance difference is often minimal for most users. Gen 4 SSDs provide more than enough speed for gaming, content creation, and everyday computing tasks at a fraction of the cost of Gen 5 drives.
2. Diminishing Returns
The jump from Gen 3 to Gen 4 SSDs brought significant real-world performance improvements. However, the leap from Gen 4 to Gen 5 offers diminishing returns for most applications. Many current games and software cannot fully utilize the bandwidth provided by Gen 4 SSDs, let alone Gen 5 drives.
3. System Compatibility
PCIe Gen 4 has been available since 2017, and many current systems support this standard. Upgrading to a Gen 4 SSD is often as simple as swapping out the drive. In contrast, Gen 5 SSDs require newer motherboards and processors, potentially necessitating a more extensive and costly system upgrade.
4. Thermal Management and Power Efficiency
Gen 5 SSDs generate more heat and consume more power than their Gen 4 counterparts due to their higher speeds. This increased thermal output can lead to throttling issues if not properly managed, potentially negating some of the performance benefits. Gen 4 SSDs strike a better balance between performance and thermal efficiency, making them easier to integrate into existing systems without additional cooling solutions.
5. Mature Technology
PCIe Gen 4 technology has been on the market for several years, allowing manufacturers to refine their designs and improve reliability. Gen 5 SSDs are still in their infancy, and early adopters may face teething issues or firmware updates as the technology matures.
6. Sufficient Speed for Current Applications
For the vast majority of users, including gamers and content creators, Gen 4 SSDs offer more than enough speed to handle current and near-future applications. Load times, file transfers, and overall system responsiveness are already excellent with Gen 4 drives, making the extra cost of Gen 5 SSDs difficult to justify for most scenarios.
Use Cases Where Gen 5 SSDs May Be Justified
While Gen 4 SSDs are the better choice for most users, there are specific scenarios where the extra performance of Gen 5 drives may be warranted:
1. Professional Video Editing and VFX
For professionals working with 8K video or complex visual effects, the increased bandwidth of Gen 5 SSDs can provide tangible benefits in terms of faster rendering times and smoother scrubbing through high-resolution footage.
2. Scientific Computing and Data Analysis
Researchers and data scientists working with massive datasets may benefit from the increased read and write speeds of Gen 5 SSDs, allowing for faster data processing and analysis.
3. Server and Data Center Applications
In enterprise environments where every millisecond counts, the improved performance of Gen 5 SSDs can translate to better overall system efficiency and reduced latency for mission-critical applications.
4. Extreme Enthusiasts and Benchmarkers
For those who demand the absolute best performance and are willing to pay a premium, Gen 5 SSDs offer bragging rights and the satisfaction of owning cutting-edge technology.
Future-Proofing Considerations
One argument in favor of Gen 5 SSDs is the potential for future-proofing. As software and games become more demanding, the extra bandwidth provided by Gen 5 drives may become more relevant. However, it’s important to consider the following factors:
- By the time Gen 5 speeds become necessary for mainstream applications, prices will likely have dropped significantly.
- The performance gap between Gen 4 and Gen 5 SSDs in real-world scenarios may remain minimal for years to come.
- Investing in a high-quality Gen 4 SSD now and upgrading later when Gen 5 technology is more mature and affordable may be a more cost-effective strategy.
Making the Right Choice: Factors to Consider
When deciding between a Gen 4 and Gen 5 SSD, consider the following factors:
- Budget: Gen 4 SSDs offer significantly better value for money in 2024.
- System compatibility: Ensure your motherboard and processor support the chosen SSD generation.
- Intended use: Evaluate whether your specific applications can benefit from Gen 5 speeds.
- Upgrade path: Consider your long-term upgrade plans and whether investing in Gen 5 now aligns with those plans.
- Capacity needs: Gen 4 SSDs are available in larger capacities at more reasonable prices compared to Gen 5 drives.
Conclusion: Gen 4 SSDs – The Practical Choice for 2024
While PCIe Gen 5 SSDs represent the pinnacle of storage technology in 2024, they come with a significant price premium and potential compatibility issues. For the vast majority of users, including gamers, content creators, and professionals, PCIe Gen 4 SSDs continue to offer the best balance of performance, value, and compatibility.
