Frequently Asked Questions
Is the Samsung 950 Pro worth the upgrade over the 850 if I only game?
For most gaming scenarios, the difference between the 950 Pro and the 850 series might be minimal. While the 950 Pro will offer faster load times in some titles that are optimized for NVMe, the vast majority of games currently benefit more from faster GPU and CPU. If you’re looking for the absolute fastest load times and have an NVMe-compatible system, the 950 Pro is the choice, but for many gamers, the 850 series provides excellent performance at a better value.
What kind of motherboard do I need for the Samsung 950 Pro?
The Samsung 950 Pro utilizes the NVMe protocol and connects via an M.2 slot that supports PCIe lanes. Therefore, you’ll need a motherboard that explicitly supports NVMe SSDs through its M.2 slot, and crucially, has M.2 slots wired for PCIe 3.0 x4 (or higher) to achieve its full potential. Older motherboards or those with M.2 slots limited to SATA or PCIe 2.0 x2 will not be compatible or will significantly bottleneck the drive’s speed.
Are the 850 EVO and 850 Pro significantly different?
Yes, while both are SATA III SSDs, the 850 Pro generally offers higher endurance ratings (TBW – Terabytes Written) and often uses higher-quality NAND flash, contributing to slightly better sustained performance and longevity. The 850 EVO is still a fantastic drive for most users, offering a great balance of performance and price, whereas the 850 Pro is targeted towards professionals and power users who prioritize maximum endurance and consistent peak performance over a longer lifespan.

How much faster is the 950 Pro in real-world usage compared to the 850?
In sequential read/write tasks like transferring large files or loading massive game assets, the 950 Pro can be 3-5 times faster than the 850 series. However, for everyday tasks like booting the OS, launching applications, or general web browsing, the difference is less pronounced, often measured in milliseconds. The 950 Pro truly shines in professional workloads that involve heavy data manipulation, large file transfers, and multitasking with demanding applications.
Is the 950 Pro still a good buy in 2024?
While the Samsung 950 Pro was a groundbreaking drive at its release, newer NVMe SSDs (including Samsung’s own 970 EVO Plus, 980 PRO, and 990 PRO) offer even higher speeds and better efficiency. If you can find a 950 Pro at a significantly discounted price and your motherboard supports NVMe, it can still offer a substantial upgrade over SATA SSDs. However, for new builds or those seeking the absolute best performance, newer generation NVMe drives are generally recommended.
Final Verdict
The Samsung 950 Pro represents a significant leap in storage technology, offering unparalleled NVMe speeds for demanding users. However, for the vast majority of consumers, including most gamers and everyday users, the Samsung 850 series provides an exceptional balance of performance, reliability, and value. The 850’s SATA interface is more than capable for typical workloads, making it the more practical and budget-friendly choice. The 950 Pro is a powerhouse for professionals, but the 850 is the smarter pick for the average user.
