The 240GB Sandisk Extreme Pro uses the same controller and NAND as its 13 months younger predecessor, the Extreme II. Comparing the Extreme II and Extreme Pro shows that average performance has increased by 10% but peak performance remains broadly unchanged. The Pro features an improved nCache which uses an SLC buffer to cache writes prior to writing them to the slower MLC NAND. In order to benefit from this improved caching, huge amounts of data need to be written for extended periods, an unlikely consumer scenario. Comparing core performance between the Samsung 840 Evo and Extreme Pro shows that the Extreme Pro averages around 12% faster than the Evo. The Extreme Pro also has a 10 year warranty but I wonder if SATA 3 will even be around at that time. Although the Extreme Pro has a superb performance profile it's not a game changer. [Jun '14 SSDrivePro]

The Sandisk Extreme II uses the 88SS9187-BLD2 controller, Marvel's latest, and Sandisk's own 19MM MLC Memory. On paper this makes an extremely good combination and the benchmarks agree. The Extreme II scored an impressive 1143 in the server orientated AS SSD Benchmark putting it amongst the more capable server drives. In terms of real world consumer performance the Extreme II also fared well achieving a real world speed index score of 570.5 MB/s, amongst the top three scores we have seen to date. The Extreme II has everything going for it apart from its price which is currently significantly above average and hurting its value rating. Because the Extreme is the newest SSD we have in our group test we expect prices will drop with time. Until then, however, there is better value to be had elsewhere. [Jun '13 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 exposes youtubers that promote overpriced/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.
