Conclusion 
Average Bench 91.7%

The 240GB Sandisk Extreme Pro uses the same controller and NAND as its 13 months younger predecessor, the Extreme II. Comparing the Extreme II and Extreme Pro shows that average performance has increased by 10% but peak performance remains broadly unchanged. The Pro features an improved nCache which uses an SLC buffer to cache writes prior to writing them to the slower MLC NAND. In order to benefit from this improved caching, huge amounts of data need to be written for extended periods, an unlikely consumer scenario. Comparing core performance between the Samsung 840 Evo and Extreme Pro shows that the Extreme Pro averages around 12% faster than the Evo. The Extreme Pro also has a 10 year warranty but I wonder if SATA 3 will even be around at that time. Although the Extreme Pro has a superb performance profile it's not a game changer. [Jun '14 SSDrivePro]

The OCZ Vector 180 has a five year warranty and is rated for 50GB/day over that time. In terms of hardware the Vector 180 is basically a rebadged two year old Vector 150. The 180 does feature "Power Failure Management Plus" which protects data that has already been written to the drive but any data that is in the process of being written is still at risk. In terms of performance the Vector 180, like its predecessor (Vector 150) is very strong. With an effective speed of 98.7% the Vector appears to hold its own with the likes of the similarly priced Samsung 850 Pro. But taking a closer look at the performance differences between the 850 Pro and Vector 180 shows that although the headline speeds are comparable, the Vector has significantly slower 4K Mixed IO speeds, this won't impact most consumers but it could be a sticking point for power users. [Jun '15 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.
