The (WD20EZRX) is Western Digital's latest green drive. I don't see what's green about it considering that it draws 5.5 watts even when idle, which is about average nowadays. With peak sequential lab read/write speeds of 150 MB/s the performance profile is approximately 20% below average for recent Hard drive. It's not all bad news as the WD Green is priced aggressively so despite its relatively weak performance it still represents reasonable value for money, at least within the 2TB category. Due to economies of scale, larger capacity drives nearly always yield better value for money. Compared to the 3GB 7200.14 Barracuda, performance is very similar but the barracuda offers 50% more capacity for 36% more money. [Dec '13 HDrivePro]

This is the latest version of Western Digital's mid-range Blue drive. At only one year of age this drive is relatively new and the performance figures reflect this. With maximum sequential speeds of 180 MB/s (both read and write) the Blue is amongst the faster drives currently available and in terms of real world performance it beats its predecessor the 2010 Blue (WD10EALS) by around 18%. The 2012 Blue has a single 1TB platter which combined with its 7200 rotation speed allows for above average performance across the board. In terms of value for money a larger capacity drive will nearly always be a better choice but within the 1TB category as a system drive, the 2012 Blue is a very reasonable, if not the best, option. [Jan '14 HDrivePro]

 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.
