The 128GB Transcend SSD370 proved to be a bit of a disappointment both in absolute terms and in comparison to its larger capacity 256GB sibling. The 128GB SSD370 is let down by its abysmal peak sequential write speed of just 158 MBps which is the lowest speed we have seen to date on a ~128GB SATA 3.0 SSD. Comparing the 256GB and 128GB versions shows that 256GB capacity drive has nearly double the write speed which is typical for larger flash based drives. In terms of value for money the 128GB SSD370 fares a little better but there are far faster and moderately cheaper alternatives available in the extremely competitive SSD market. [Oct '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.
