Conclusion 
Average Bench 76.2%
Average Bench 101%

The Sandisk Extreme was once a good choice of SSD thanks to its extremely (pun intended) competitive price. In terms of performance the Extreme would of course obliterate any regular hard drive but at 16 months old the Extreme can no longer compete with more recent SSDs. In terms of typical consumer workloads the Sandisk delivers below average performance and is even less capable when it comes to server workloads scoring a total of just 761 on the AS-SSD benchmark. The weaknesses in performance are a consequence of the now dated Sandforce SF2281VB1 controller which delivers sub-optimal compressible transfer rates. The best thing the Sandisk Extreme has going for it is that its successor, the Extreme II, was just recently released. [Jun '13 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.
