Almost two years old, the Samsung 830 is one of the oldest SSD's in the group test. The 830 has a reasonably consistent performance profile scoring slightly above average (446 MB/s) for real world use and slightly below average for server use. In all probability the 830 is nearing its end of life and as a result is retailing for approx £50 more than it was just a few months ago. Owners of this drive should feel no pressure to upgrade as the real world performance gains will not be significant but people looking to make a new purchase should steer clear as at its current price of £180 there are far better deals to be had elsewhere. [Apr '13 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.
