Conclusion 
Average Bench 746%

The Crucial T705 is a slightly improved version of the T700. Both are among the first PCIe 5.0 SSDs, offering peak data rates double those of PCIe 4.0. The T705 can reach staggering burst sequential read and write speeds of 15 and 12 GB/s. However, out of cache performance still lies within PCIe 4.0 limits so the T705 doesn’t have a PCIe 5.0 advantage during sustained workloads. The T705 offers around a 5% effective speed advantage over the T700 which is not justifiable at current prices (1TB = $180, 2TB = $300, 4TB = $500). While it may appeal to users looking for almost unparalleled burst performance, most users won’t notice much improvement compared to the WD Black SN850X because of other bottlenecks in a typical system. [Jun '24 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.
