At four months old, the 128GB Toshiba Q Series Pro is the newest SSD in the group test. It's always nice to see new drives pushing established speed boundaries and the Q Series Pro does exactly that. With peak and average sequential read/write speeds of 521/481 and 422/333 MB/s the Q Series Pro beats the 128GB group average peak write speed by 45% and is bested only by the Samsung Evo. A particularly impressive aspect of the Q Series Pro's performance profile is its mixed IO performance where it beats the average of the group leaders by a stunning 50% and sets new sequential/4k mixed IO records of 502/40.4 MB/s. The ability to handle concurrent read and write operations well means that the Q Series Pro will rarely pause for breath, even when faced with varying IO demands, a great server orientated trait. Overall the Q Series Pro has a very robust performance profile and is well priced making it one of the top 128GB SSDs of 2014. [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.
