i sell child to buy good ssd [Apr '19 userbanchmark]

MORE DETAILS

The AMD Radeon R7 SSD is manufactured by OCZ (Toshiba). The release of the R7 is in line with OCZ's approximate six-monthly release cycle. Apart from newer NAND memory, the R7 has the same components as the OCZ Vector 150. Comparing the AMD R7 and Vector 150 shows that peak performance is broadly unchanged. We don't have any user samples for the new R7 yet but based on components, it's reasonable to assume that real-world effective speeds will also be comparable to the Vector 150. Although the 240GB R7 SSD is a strong performer, disappointingly, it brings nothing new to the table in terms of hardware. Unless OCZ/Toshiba can pull something out of the bag they will continue to loose market share to Samsung who are still managing to innovate with each of their releases; most recently the 850 pro series.  [Aug '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.
