Conclusion 
Average Bench 89%
Average Bench 85.8%

Comparing the 150 to the original Vector is disappointing, the newer 150 actually offers marginally worse performance than its predecessor. A strange result but verified (at least partly) by figures on OCZ's own website: 100K 4K read IOPS for the Vector vs 90K 4K read IOPS for the 150. The newer 150 comes with a 5 year warranty which covers 50GB/day vs. the original Vectors 20GB/day but even this should be taken with a pinch of salt considering that the OCZ stock price is currently trading at around seven cents per share, an all time low. Despite the fact that new Vector 150 performs worse than its predecessor it's still a very competent performer and if prices drop, it has the potential to become a decent value proposition. In the meantime however there are far better deals available elsewhere.  [Dec '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 the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
