Conclusion 
Average Bench 85.5%
Average Bench 80.6%

The HyperX 3K is an updated version of the regular HyperX, the only difference between the two SSDs is the grade of NAND flash. The regular HyperX's NAND flash is rated at 5,000 erase cycles vs 3,000 on the 3K version so broadly speaking the number of erase cycles before drive failure on the newer drive is approximately 40% less than on the original HyperX. The distinction is largely irrelevant for consumer users because even after 10 years neither of the drives are likely to come even close to their maximum number of erase cycles. As expected both HyperX's have very similar performance profiles which can be seen in this direct comparison of the two drives. Although the HyperX SSDs were strong contenders on release they are showing their age now and can no longer compete amongst the newer drives from Samsung and Plextor which are both cheaper and faster. [Jan '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.
