With peak sequential read/write speeds of 140 and averages of 120 MB/s the 3TB WD Red is around 25% slower than the group leaders. If the Red is used in a NAS (Network Attached Storage), that won't make much difference because the vast majority of home networks still operate at Fast Ethernet (~10 MB/s), even users with faster Gigabit (~100 MB/s) networks will be limited by their network bandwidth before the drive. I could assume that any of our drives are for use in a NAS but that of course doesn't excuse sub-par performance because they could equally be used in a desktop. It's true that the power consumption (4.4W) on the Red is lower than average (6W) but the performance hit isn't justified. Even assuming continuous usage, those extra couple of watts for something like the Seagate Baracuda 7200.14 amount to a few pounds a year at most. At £133 this dive is both overpriced and offers sub-optimal performance. [Feb '14 HDrivePro]


Compared to the Seagate Barracuda 7200.14 3TB there are no tangible upsides to this drive. The ONLY benefit seems to be a 2W power saving whilst the drive is active. [Nov '12 HDrivePro]


Hard Drive User Rankings (Charts) November 2015 HDD Rankings.

Welcome to our consumer Hard Drive comparison. We calculate effective speed which measures performance for typical consumers. Effective speed is adjusted by cost per GB to yield value for money. Calculated values don't always tell the whole picture so we check them against thousands of individual user ratings. The customizable table below combines these factors and more to bring you the definitive list of top HDDs. Share your opinion by voting. [HDrivePro]
