The 256GB Transcend SSD370 sports a Silicon Motion (SM2246EN) controller coupled with Micron 20nm synchronous MLC NAND. With peak sequential read/write speeds of 520/290 MBps and peak 4k read/write speeds of 29/116 the SSD370 has an effective speed which is amongst the bottom 25% of ~250GB drives. The effective speed is weighed down by a relatively weak sequential write speed of just 290 MBps. The performance highlight for the SSD370 is its ability to deal with mixed 4k IO which is arguably one of the best real world indicators. At current prices the SSD370 can't compete as there are both cheaper and faster alternatives on the market but prices are almost certain to drop at which time the SSD370 will fare far better in terms of value. [Oct '14 SSDrivePro]

 Frequently Asked Questions

 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.
