Conclusion

The OCZ Vertex 460 replaces the Vertex 450. The main difference between the two is a change from Intel/Micron (IMFT) 20nm MLC NAND to Toshiba 19nm MLC NAND, a fitting move considering that Toshiba acquired OCZ shortly before the Vertex 460's release. Comparing the Vertex 460 and 450 shows that the two drives are broadly on a par in terms of performance. In terms of pricing the Vertex 460 is priced reasonably considering its age, I expect prices will drop rapidly as retailers build stocks of the relatively new drive. At current prices the 240GB Vertex 460 represents above average value for money but struggles to compete with its slightly more expensive sibling, the Vector 150. Comparing the 460 and 150 shows that Vector 150 leads in terms of effective speed by 10% but only costs 5% more than the 460. [Mar '14 SSDrivePro]

The 120GB Sandisk Extreme II proved to be a disappointment. I was expecting the same blistering performance as I saw on its larger 240GB sibling but that proved not to be the case. Comparing the 120GB and 240GB Extreme II's reveals that the larger 240GB version has peak speed ratings that are approximately 35% faster that the 120GB Extreme II. The main weakness of the 120GB Extreme II is its sequential write speed which is just 305 MB/s vs 492 MB/s on the 240GB version. Reduced write ability at lower capacities is explained by fewer NAND modules which reduce a controllers ability to parallelize slow write operations across different memory banks. Overall the Sandisk Extreme II sits amongst the bottom 20% of performers in the 120-128GB capacity category. Several of the drives in the group test have comparable performance at both the 120 and 240 GB capacities, those drives are the ones to go for. [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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
