While being priced similarly and performs similarly to competitor SSD. This PCI-E 4.0 SSD is priced little bit lower than other PCI-E 4.0 SSDs. Offering one of the fastest R/W speeds, this SSD pretty much guarantee having to wait only few seconds to transfer most (if not the entire) of your photos, videos, documents or game libraries. Random 4K R/W is slightly lower when compared with Intel 900p/905p but worth it for very fast and new PCI-E 4.0 interface and obviously 1TB of storage. Suggested to pay 10 USD extra for heatsink though. [Oct '19 ColdSpy]

 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.
