However, real-world performance can vary depending on factors such as system configuration and workload. In our tests, the WD Black SN850X consistently outperformed the Samsung 980 Pro in sequential read/write operations, with a slight edge in random read/write speeds as well.
Endurance and Reliability
SSDs have a limited lifespan due to the finite number of write/erase cycles they can withstand. The Samsung 980 Pro offers a total bytes written (TBW) rating of 600 TB for the 1TB model, while the WD Black SN850X boasts a slightly higher TBW rating of 650 TB. Both drives come with a 5-year limited warranty, providing peace of mind against premature failure.
Controller and NAND Type
The Samsung 980 Pro employs Samsung‘s own Elpis controller, while the WD Black SN850X utilizes the Marvell 88SS1092 controller. Both controllers are highly efficient and deliver excellent performance. In terms of NAND type, the Samsung 980 Pro uses TLC (Triple-Level Cell) NAND, while the WD Black SN850X utilizes BiCS5 (3D TLC) NAND. TLC NAND offers higher capacity and cost-effectiveness, while BiCS5 NAND boasts higher endurance and performance.
Form Factor and Compatibility
Both the Samsung 980 Pro and WD Black SN850X come in the standard M.2 2280 form factor, making them compatible with most modern motherboards and laptops. They support the PCIe 4.0 x4 interface, which provides ample bandwidth for optimal performance.
Software and Features
Samsung offers the Magician software suite for the 980 Pro, which includes tools for monitoring drive health, optimizing performance, and securing data. WD provides the WD Dashboard software for the Black SN850X, which offers similar functionality. Additionally, both drives support TRIM and S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) for enhanced drive management.
Pricing and Value
The Samsung 980 Pro and WD Black SN850X are competitively priced within their respective performance tiers. The 1TB model of the Samsung 980 Pro typically retails for around $130, while the 1TB model of the WD Black SN850X is slightly more expensive at around $150. Ultimately, the best value depends on your individual needs and budget.
Final Thoughts: Choosing the Right SSD for Your Needs
The Samsung 980 Pro and WD Black SN850X are both exceptional SSDs that offer blazing-fast speeds and ample storage capacity.
