Main features
1. Samsung V-NAND Technology
The 850 PRO is the first SSD series based on Samsung's revolutionary 3D V-NAND technology. Unlike conventional NAND memory, which is arranged flat on one level, Samsung's V-NAND technology stacks the memory cells vertically in multiple layers. This increases storage density, improves performance and reduces power consumption.2. Fast reading and writing speed
With a sequential read speed of up to 550 MB/s and a write speed of up to 520 MB/s, the Samsung SSD 850 PRO offers outstanding performance. This enables fast booting, short loading times and a noticeable acceleration of applications compared to conventional HDDs or older SSDs.3. Superior IOPS performance
The random read and write speed, measured in IOPS (Input/Output Operations per Second), reaches up to 100,000 IOPS (read) and 90,000 IOPS (write). This means that the SSD is excellent for multitasking and offers smooth performance even under high demands.4. Dynamic Thermal Guard
The integrated Dynamic Thermal Guard automatically monitors and controls the temperature of the SSD to prevent overheating. This protects the data and ensures that the SSD delivers optimal performance even under demanding working conditions.5. Energy efficiency
Thanks to V-NAND technology and the efficient controller, the 850 PRO offers approximately 40% higher energy efficiency compared to previous models. The SSD consumes less power, which is particularly beneficial for use in laptops and mobile devices as it extends battery life.6. 10 year guarantee
The Samsung SSD 850 PRO comes with a 10-year warranty, which underlines the durability and reliability of the SSD. Samsung offers up to 150 TBW (Terabytes Written), which means an extremely long lifespan for the majority of users.7. Magician Software
Samsung Magician software allows the user to easily manage the SSD, offering features such as firmware updates, performance optimization, benchmarks, and secure data deletion. Additionally, RAPID (Real-time Accelerated Processing of I/O Data) technology allows the user to use the system's DRAM (RAM) memory as a cache, which can further increase performance.8. Security through AES encryption
The SSD supports 256-bit AES hardware encryption, which securely protects data without affecting the performance of the hard drive. It is also compatible with TCG Opal 2.0 and IEEE 1667, making it ideal for use in business environments where data protection and security are a high priority.Areas of application
1. High-end gaming
The Samsung SSD 850 PRO is ideal for gaming PCs. The fast read and write speeds ensure shorter loading times, smoother gaming performance and the ability to run multiple applications in parallel.2. Content creation and multimedia editing
The high performance and reliability make this SSD ideal for content creators who work with large files such as 4K videos, photo editing and music production. Users particularly benefit from the speed and durability of the 850 PRO in professional applications such as Adobe Premiere, Photoshop or other computationally intensive programs.3. Workstations and professional applications
The 850 PRO is ideal for use in workstations that are often under constant load and require high reliability. It not only offers high performance, but also a long service life and data security thanks to AES encryption.4. Servers and virtualization
The 850 PRO can also be used in smaller servers or in virtualized environments. It offers sufficient storage space and performance to support multiple virtual machines.5. Laptop upgrade
The SSD's low power consumption and high performance also make it ideal for laptop upgrades. Battery life is improved and the device runs significantly faster, making it an optimal choice for mobile users.Comparison with other models
- Samsung SSD 850 EVO: The 850 EVO series also offers strong performance but at a slightly lower price. However, compared to the 850 PRO, it offers a shorter warranty period (5 years) and a lower TBW (75 TBW for the 256 GB version). So the 850 PRO is better suited for more intensive applications and a longer lifespan.
- Samsung SSD 860 PRO: The successor 860 PRO series builds on the strengths of the 850 PRO, but offers slightly improved write speeds and a higher TBW. However, when it comes to value for money, the 850 PRO remains an excellent choice, especially if the user does not need the full range of features of the 860 PRO.
Advantages and disadvantages
Advantages:
- Outstanding read and write speeds.- Long lifespan thanks to V-NAND technology and high TBW.
