This is yet another Sandforce 2881 based SSD from Kingston, this time coupled with newer 19nm Nand flash. In terms of performance the V300 is nothing we haven't seen before with other Sandforce based SSDs. A side-by-side comparison with the HyperX shows that the two drives have a near identical performance profile which is more than a little disappointing given that the V300 is 16 months newer. With a sequential write speed of just 280 MB/s the V300 lags the group leaders by 62%, an expected result for a Sandforce based drive. To conclude, Kingston aren't offering anything new with the V300, consequently there are far faster (and cheaper) drives available elsewhere including the excellent Samsung Evo which is the current group leader. [Jan '14 SSDrivePro]

The 840 Pro is stunning. Samsung have created a completely in-house package including both the controller and their own new 21nm toggle mode NAND. On release (Oct '12) this was the fastest performing deep queue depth consumer grade SSD available. Fast forward six months (Apr '13) and the 840 Pro still holds both the random read/write deep queue depth speed records of 384 MB/s and 326 MB/s, impressive considering how fast the SSD space tends to move. There are no obvious weaknesses, in-fact the 840 pro takes first place in nearly all of the speed categories and is only seriously rivalled by one drive, the OCZ Vector. To conclude, in terms of both outright performance, particularly server orientated, and value for money the 256GB and 128GB 840 Pros are amongst the top handful of drives currently available. [Jun '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.
