The WD Black SN850X has a superb consumer performance profile. As well as offering solid burst speeds of 5 GB/s, the SN850X also offers respectable out of cache performance. At current prices (1TB $90 USD, 2TB $145 USD and 4TB $290 USD) the WD Black SN850X is our top value pick at every capacity. [Jun '24 SSDrivePro]

MORE DETAILS

The Samsung 970 Pro is a third generation NVMe PCIe SSD which replaces the 960 Pro. It comes in a M.2. form factor and features Samsung’s latest Phoenix controller and 64 layer proprietary 3D MLC NAND. MLC NAND has better write consistency but is more expensive than the TLC NAND found in the 970 Evo. The 970 Pro demonstrates a 16% increase in peak sequential write speed over the 960 Pro. There are also improvements in random read and write speeds. Interestingly this iteration of Pro SSDs come with a price cut, with the 512GB retailing at just $250 and the 1TB at $500, whilst at the time of writing, the 512GB 960 Pro is $315. The 970 Pro targets professionals who may rely on Samsung’s 5 year or 600TBW warranty and who may need its extended write performance. But, for most users who rarely transfer more than 22 GB at a time (this is the size of the SLC cache the 500GB 970 Evo), the cheaper 970 Evo may represent better value for money. [May '18 SSDrivePro]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
