When selecting the right SSD for our computers, we often compare models to find the one that best suits our needs. Samsung’s 970 EVO, 970 EVO Plus, and 970 PRO are commonly scrutinized. All three are NVMe SSDs, a standard that defines a more efficient protocol than the older SATA connection, allowing for higher speed and better performance in data transfer.
Each model brings its own strengths to the table. The Samsung 970 EVO uses 64 layers of V-NAND technology, while the 970 EVO Plus steps up with 96 layers, promising better performance and durability. Meanwhile, the 970 PRO boasts a 2-bit MLC V-NAND, offering the highest endurance and speed, which is ideal for heavy workload environments. The differences between these models lie not just in their memory architecture but also in their target audience and usage scenarios.
Understanding those key specifications enables us to make informed decisions matching our usage patterns with the appropriate drive capabilities. Solid state drives like the ones from the Samsung 970 series are pivotal for users looking to enhance their computer’s responsiveness and reduce load times, whether it’s for gaming, content creation, or general productivity tasks.

Comparing Performance and Endurance
When considering the 970 EVO, EVO Plus, and PRO, it’s essential to dissect not just the raw speed but also how long they can maintain peak performance. Let’s look into the specifics of each drive’s capabilities.
Speed and Sequential Read/Write
| Model | Sequential Read (up to) | Sequential Write (up to) |
| 970 EVO | 3,500 MB/s | 2,500 MB/s |
| 970 EVO Plus | 3,500 MB/s | 3,300 MB/s |
| 970 PRO | 3,500 MB/s | 2,700 MB/s |
TBW and Endurance Ratings
Our investigation shows that the Total Bytes Written (TBW) rating, which indicates endurance, differs among our contenders. The 970 PRO leads with the highest endurance rating, followed closely by the 970 EVO Plus, whereas the 970 EVO has a lower TBW, reflecting its positioning as a more cost-effective solution.
IOPS and Random Read/Write Speeds
Design and Technologies
In exploring the Samsung 970 EVO, 970 EVO Plus, and 970 PRO, we focus on the design and technologies that set these models apart. Each model utilizes cutting-edge technologies tailored for different users.
Form Factor and Interface
The form factor for all three models – the 970 EVO, 970 EVO Plus, and 970 PRO – is the M.2 (2280). This compact size is ideal for laptops and small-form-factor PCs. All three SSDs use the NVMe interface over a PCIe Gen3.0 x4 connection. This interface delivers higher bandwidth and lower latency compared to SATA SSDs.
We ensure that they are compliant with the NVMe 1.3 protocol, which enhances their performance and efficiency even further.
V-NAND Technology and Firmware
Samsung’s V-NAND technology is a form of 3D NAND that stacks memory cells vertically. This significantly increases density and performance while minimizing power consumption. Here’s how the V-NAND technology and firmware contribute to the functionality of each model:
| Model | V-NAND Layers | Controller |
| 970 EVO | 64-layer | Samsung Phoenix |
| 970 EVO Plus | 96-layer | Samsung Phoenix |
| 970 PRO | 2-bit MLC | Samsung Phoenix |
The 970 EVO and EVO Plus feature 3-bit MLC V-NAND with the EVO Plus employing a higher layer count, which results in better performance and endurance. The 970 PRO, on the other hand, uses a 2-bit MLC, leading to even greater durability and performance under intensive workloads.
The firmware across all models is meticulously designed to extract the most from the V-NAND structure and the Phoenix controller. Through frequent updates, we maintain smooth and efficient operation, ensuring each SSD performs at its peak.
Pricing and Warranty Information
When comparing the Samsung 970 EVO, 970 EVO Plus, and 970 PRO, we consider not only their performance but also how much value they offer for their price and the warranties provided. Price and warranty can greatly influence the decision-making process, especially when the differences in features and capabilities are subtle.
Cost and Value Proposition
| Model | Price Range | Value Proposition |
| Samsung 970 EVO | Moderately Priced | Cost-effective for mainstream users |
| Samsung 970 EVO Plus | Slightly Higher | Better performance per dollar |
| Samsung 970 PRO | Premium | Top-tier for professionals |
The 970 EVO and 970 EVO Plus offer a solid balance between price and performance, making them suitable for general usage and gaming. For professional users with intensive workloads, the 970 PRO, while being the most expensive, offers the highest endurance and performance, justifying its price.
Warranty Terms and Coverage
All three models come with a five-year limited warranty.
The warranty implies that Samsung ensures the drives will not fail under normal operational conditions within this period. While the warranty terms are similar, it’s important to note that the durability and longevity of the PRO version can provide additional assurance for users requiring maximum reliability. The limited warranty does include certain conditions, and users are encouraged to understand these fully to ensure they are covered.
Additional Considerations and Competitors
When evaluating the Samsung 970 EVO, 970 EVO Plus, and 970 PRO, it’s crucial we look beyond raw performance specifications. Software integration and competing products create a broad ecosystem where these SSDs operate.
Software and Efficiency
Efficiency isn’t just about lower power consumption; it’s also about effective use of the drive’s resources and capabilities. Our SSDs incorporate advanced V-NAND technology, making them highly efficient both in terms of energy and data handling – crucial factors for users requiring peak performance for extended periods.
Competing SSD Models
Competition in the market is fierce, with several brands offering competing models that challenge our Samsung SSD range:
| Brand | Model | Notable Feature |
| Western Digital | WD Black SN750 SSD | High throughput for gaming |
| Intel | Optane SSD 905P | Exceptional endurance rating |
| ADATA | XPG SX8200 Pro | Strong price-to-performance ratio |
| Toshiba | OCZ RD400 | Good all-round performance |
Each brand brings its unique advantages to the table. Our Samsung drives compete by offering a blend of reliability, performance, and capacity options. It’s important to note, for example, that the Intel Optane SSD 905P, while pricier, offers exceptional endurance, and the WD Black SN750 stands out in gaming environments. A potential buyer must consider individual needs, whether it’s blazing-fast write speeds or a drive that offers longevity under high write volumes.
