Conclusion 
Average Bench 113%
Average Bench 74.7%

The Mushkin Chronos and Chronos Deluxe are both Sandforce 2881 based SSDs from Mushkin. The only difference between the two is their NAND Flash: Intel asynchronous 25Nm for the Chronos vs Toshiba 32Nm Toggle Mode for the Deluxe. The 32Nm Toggle NAND supports far higher write speeds as can be seen from this direct performance comparison of the two drives. Overall the Chronos Deluxe performs slightly above expectations for a Sandforce SF2281 drive, it has reasonable read speeds but still struggles when faced with writing incompressible data. With an effective (real world) speed of 347 MB/s the Chronos Deluxe lags the group leaders by 50% and as such there are far better drives, such as the Samsung Evo, available in today's market. [Jan '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 the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
