Conclusion 
Average Bench 86.9%
Average Bench 74.1%

The 120GB Kingston HyperX 3K is nearly two years old, several generations of SSD have passed since its original release. Better 120GB SSDs have more NAND modules than the old HyperX and are able to write faster than the peak 234 Mb/s achieved by the HyperX 3K. The HyperX 3K also has a Sandforce 2281 controller which is unable to write compressed data as well as its more recent competition. All that said the HyperX still has an effective speed of 367 MBps which is respectable and far faster than even the best mechanical drive. With peak 4K read/write speeds of 33/110 MB/s the HyperX 3K also has competent small file performance. To summarize as a current value proposition the HyperX 3K struggles, simply because the likes of Samsung and OCZ have innovated and moved forward in the two years since the HyperX 3K was released. [Feb '14 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 the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
