Samsung has long dominated the NVMe market, but the recent release of the Samsung 990 EVO Plus has blurred the lines between “mainstream” and “flagship” storage. While the Samsung 990 Pro has been the gold standard for PCIe 4.0 performance since its launch, the new EVO Plus offers surprisingly similar speeds at a lower price point.
In this Samsung 990 Evo Plus vs 990 Pro comparison, we break down two of Samsung’s most popular PCIe Gen4 NVMe SSDs to help you decide which one fits your needs best.
Both drives are designed for fast boot times, smooth gaming, and demanding workloads—but they target different types of users. The Samsung 990 Evo Plus focuses on efficiency and value, while the Samsung 990 Pro is built for maximum performance and endurance.
In this guide, we dive deep into the Samsung 990 EVO Plus vs 990 Pro debate to see if the Pro’s dedicated DRAM still justifies its premium, or if the more power-efficient, hybrid-interface EVO Plus is the new king of value.

Key Takeaways
Before we look at the specific pros and cons, here are the most important things to know about the Samsung 990 EVO Plus vs 990 Pro:
- The DRAM Gap: The 990 Pro features dedicated DRAM, which helps it maintain higher speeds during massive, sustained file transfers (50GB+). The EVO Plus uses Host Memory Buffer (HMB) technology, leveraging a tiny bit of your system’s RAM instead.
- Thermal Efficiency: The 990 EVO Plus runs cooler and is more power-efficient, making it a superior choice for thin laptops where airflow is limited.
- Gaming Performance: In actual game loading tests, the difference is negligible. Both drives will load modern titles in almost identical timeframes.
- PCIe 5.0 Support: Interestingly, the EVO Plus supports PCIe 5.0 (though only on 2 lanes), providing unique versatility for newer motherboards.
Real-World Performance Breakdown

On paper, the Samsung 990 Evo Plus vs 990 Pro specs look very close, but real-world usage tells a clearer story. In everyday tasks like booting Windows, launching apps, or loading games, both SSDs feel equally fast. System startup times are nearly identical, and common applications open instantly on both drives.
The difference appears during sustained workloads. When transferring large files continuously or handling heavy multitasking, the Samsung 990 Pro maintains higher speeds for longer due to its DRAM cache. Meanwhile, the Samsung 990 Evo Plus may dip slightly once its cache is saturated—but this is rarely noticeable for average users.
For most people, real-world responsiveness feels the same. Only power users pushing their storage hard every day will consistently benefit from the Pro’s extra headroom.
Gaming Performance Analysis

For gaming, the Samsung 990 Evo Plus vs 990 Pro debate is surprisingly simple: there is virtually no difference.
Both SSDs:
- Deliver extremely fast game load times
- Handle texture streaming smoothly
- Prevent stutters in large open-world titles
- Fully support DirectStorage-style workloads
In real gaming scenarios, frame rates are not affected by choosing the Pro over the Evo Plus. Level loading times differ by fractions of a second—often impossible to notice without a stopwatch.
If you’re building a gaming PC or upgrading a PS5-compatible NVMe SSD, the Evo Plus already provides everything modern games require. The Pro does not offer a meaningful gaming advantage unless gaming is combined with heavy background tasks like recording, streaming, or asset creation.
Thermals & Power Efficiency
Thermal behavior is an important but often overlooked factor in the 990 Evo Plus vs 990 Pro comparison.
The 990 Evo Plus is designed with efficiency in mind:
- Runs cooler under sustained loads
- Draws less power
- Better suited for laptops and small-form-factor PCs
The 990 Pro, while faster under heavy workloads, tends to run hotter, especially during long write sessions. For desktops, this is easily managed with motherboard heatsinks or aftermarket cooling, but in compact systems, it can matter.
If you care about battery life, quiet operation, or lower temperatures, the Evo Plus has a clear advantage.
Price-to-Performance Analysis

This is where the Samsung 990 Evo Plus vs 990 Pro comparison becomes decisive for most buyers.
While the 990 Pro is technically faster, its real-world advantage is limited to specific professional workloads. The Evo Plus delivers around 90–95% of the experience at a noticeably lower cost per GB.
In short:
- The Evo Plus offers better value for money
- The Pro charges a premium for performance most users won’t fully utilize
Unless your workflow demands constant high-end storage performance, the Evo Plus wins on price-to-performance.
Who Should NOT Buy Each SSD
Who Should NOT Buy the 990 Evo Plus
