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]

Five year warranty, this SDD will outlive most others (or at least it should). New technology, 64 layers of 3D NAND flash. It's too early to to do proper comparisons in terms of longevity but I'm sure it'll last me a while. This 545s 2.5 inch SSD is even faster than my Crucial MX300 M.2 SSD. I got a random read/write 4k speed of 100 MB/s + (with CrystalDisk Mark 5) that's unheard of on a SATA drive. Sure, this isn't NVMe or Optane, but that's okay, for the price ($165) I'm still pretty satisfied with this SSD. [Dec '17 morahman7vn]

 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 the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
