Very modern day SSD with plenty of quick and good value storage. Just bought it for 125$ CAD and it's incredibly quick and Its great value. The advertised speed is 2400mbs (2.4GB) with a 5-year warranty. Definitely one of the best value SSDs on the market.

Amazing performance for the price and solid reliability.

Western Digital replaced TLC with QLC NAND in Blue SN550 (recognizable by firmware id 233010WD). This is why the peformance shows terrible consistency. The new SN550 with TLC performes significantly worse then the old one. WD is supposedly offering a free replacement.

 Frequently Asked Questions

 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.
