Average Bench: 95.5% (14th of 995)

Based on 12,949 user benchmarks.  Models: ST3000DM008-2DM166, ST3000DM008-2DM1, ST3000DM 008-2DM166, ST3000DM ST3000DM008-2DM1, Seagate ST3000DM008-2DM1

The new 3TB Seagate Barracuda 2016 (ST3000DM008) replaces its hugely successful predecessor, the 3TB Barracuda 7200.14 2011 (ST3000DM001). Comparing performance between the two models shows that the newer drive has 12% faster sequential speeds, comparable 4K speeds, improved mixed sequential speed and reduced mixed 4K speed. Overall, the effective speed is 12% faster on the 2016 model. Since there is normally little price difference between the two models the 2016 version is the clear winner especially for use as a backup drive with its impressive sequential read and write speeds of nearly 200 MBps.

I bought this new HDD for all my data accumulated in 15 years. Almost 2T of data. I have a lot of data types: zip, office, eml, rar, pdf, mod, waw, mov, png, jpg, etc, etc.... Smoothly transferred all data . I dont received any failure yet. I hope will not in future! :)

With, after under four years of not so intensive use in a Synology DS413J NAS, a failure rate of 100% for the two Seagate ST3000DM001 drives I used in it , it is safe to say that this Barracuda series was a total disaster as is also seconded by many internet testimonials. So whether this drive was the fastest or not is totally irrelevant if it proves to be as unreliable as it is. Needles to say I think that I didn't replace them by other Seagate drives. The Hitachi 3TB drives I'm also using in the same NAS ran (an still run !) consistently cooler. Shame on you Seagate.
