The 32GB Sandisk Ultra Fit has both a tiny form factor and a respectable performance profile. With peak sequential read/write speeds of 136/55 MBps and peak 4K read/writes of 6.6/2.0 MBps the 32GB Ultra Fit sits amongst the top 25% of 32GB flash drives. In terms of value for money the Ultra fit fares even better and is bested only by the Sandisk Extreme. Comparing the 32GB Extreme and Ultra Fit shows that the Extreme has over double the effective speed yet the extreme is only 32% more expensive than the Ultra Fit. To conclude, the 32GB Ultra Fit has good peak performance (sustained performance is far less impressive) but its key strengths are its tiny form factor and reasonable price tag. [Oct '14 USBFlashPro]

 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.
