Tom's Hardware SSD Performance Test Shows Minimal Effect on Game Frame Rates

On August 9, 2023, Tom's Hardware recently conducted a comparative test of SATA and PCIe-based SSDs across multiple game titles, revealing that faster SSD generations produce only minor improvements in load times with virtually no impact on gaming performance metrics.

Test Methodology and Key Findings

The evaluation assessed SSD speeds for SATA, PCIe 3.0, PCIe 4.0, and PCIe 5.0 interfaces in 11 AAA games, focusing on their influence on average frame rates and load duration. PCI Express (PCIe) refers to a high-speed serial interface for data transfer between components like SSDs and motherboards, ensuring efficient connectivity.

PCIe SSDs, which use flash memory for rapid data access, demonstrated minimal variation in performance across generations when it comes to in-game rendering. The test showed that while faster PCIe versions reduce loading screens by fractions of seconds, their effect on actual gameplay frame rates remains negligible, suggesting that other factors dominate gaming experiences.

Tested Game Titles

11 popular 3A games were included in the analysis, such as Forspoken, which is an action-adventure title, and心灵杀手2, a horror-themed game known for its immersive graphics.

1. Forspoken
2. 心灵杀手2
3. 瑞奇与叮当：时空跳转
4. 蜘蛛侠2
5. 星空
6. 毁灭战士：黑暗时代
7. 死亡空间重制版
8. 赛博朋克2077
9. 其他 titles not specified in the data

This outcome implies that investing in higher PCIe SSD versions might be more beneficial for reducing wait times rather than enhancing core gaming mechanics.

PCIe NVMe SSD：游戏体验提升关键指标简析

近日发布的测试数据显示，在常规帧率表现方面，各类接口SSD差异极小，但低帧率场景下，传统SATA接口存储设备与PCIe接口NVMe固态硬盘存在明显性能差距。测试表明，游戏加载大型材质贴图时，SATA SSD受限于40GB/s带宽，可能引发瞬间帧率波动。

帧率表现全面解析

根据30分钟《赛博朋克2077》等大型游戏的实际测试，PCIe NVMe SSD展现出1.2×于SATA SSD的持续性能优势。节点选择方面，PCIe NVMe SSD在1%低帧率场景下优势更为明显，游戏帧率波动范围控制在±1.8以内，有效解决了传统存储设备在资源调用高峰期可能出现的画面撕裂问题。

技术原理解读

业内观察人士指出，SSD接口类型主要分为SATA、PCIe等标准。其中PCIe 4.0 x4接口最高可達40GB/s传输速率，较SATA 6Gb/s接口（约7300MB/s）在实际应用场景中带来近2.8倍的加速效果，这对60帧以上高画质游戏体验影响尤为显著。

关键性能差异对比

1. 平均帧率：传统SATA SSD≤62.4帧，PCIe NVMe SSD≥75.6帧
2. 最小帧率波动：PCIe NVMe SSD较SATA SSD降低37.6%
3. 材质加载响应：PCIe NVMe SSD较SATA SSD缩短约51%

存储技术演进方向

有硬件工程师分析指出，随着游戏开发者开始重视多线程场景下的帧率表现，存储设备的接口类型与性能参数将在未来4-5年成为选购游戏硬件的核心考量因素之一。

【PCIe SSD性能演变与应用实际测评】

当前PCIe SSD从3.0进阶到5.0的迭代进程中，各代际间性能差距已逐渐收窄。通过实际性能测试发现，在游戏场景中，数据传输带宽提升并未转化为实质性帧数增长。

其中PCIe 3.0的理论带宽为8GT/s，而PCIe 4.0提高到16GT/s，PCIe 5.0则跃升至32GT/s，但这些参数提升在实际应用中表现得较为隐性。

载入时间对比显示，NVMe PCI-Express SSD相比传统SATA SSD优势明显，多个游戏测试用例中，前者在载入速度上可使耗时同比缩短数倍。

从PCIe 3.0升级到4.0或5.0，纵向来看带宽增加，但横向看游戏体验提升幅度有限。

综合评估来看，选购SSD时需权衡性能增长与实际应用需求。在过去，追求更高PCIe规格，而现在，应该更关注整体存储解决方案的适用性。

Solid State Drives Comparison PCIe Generations Impact on Gaming

The PC gaming market has seen a significant technological shift from PCIe 3.0 to PCIe 5.0 SSDs. While PCIe 5.0 theoretically offers doubled bandwidth compared to its predecessor, real-world game loading time tests reveal minimal performance differences. According to independent analysis by Tom's Hardware, most current gaming applications utilize random I/O operations of 32KB or 64KB block sizes at consistent queue depths. The raw, unattainable bandwidth frequently cited by manufacturers cannot translate to measurable gameplay improvements.

Selecting Appropriate Storage for Optimal Gaming Experience

The testing methodology focused on common gaming scenarios, evidencing that storage technology advancements beyond a certain threshold do not provide proportional benefit. Accordingly, consumers should strategically allocate their hardware budgets. Resources dedicated to graphics cards, central processing units, and system memory consistently demonstrate more substantial impact on overall gaming performance.

Storage selection should primarily consider capacity and cost efficiency. Mid-tier PCIe 4.0 SSD solutions effectively meet the vast majority of gaming requirements at a reasonable investment level. This practical recommendation aligns with sound hardware optimization principles in contemporary PC gaming environments.

• PCIe 5.0 SSDs offer theoretical performance improvements
• Game performance remains more constrained by other components
• Sudden changes in loading times were not observed in testing
• Optimal investment prioritizes visible performance components
• Potentially misleading marketing claims about SSD performance
