The 3TB Toshiba DT01ACA300 is 3.5" desktop hard drive. Like its 2TB sibling, the DT01ACA300 sports a rotation speed of 7,200 RPM and has a relatively low peak/idle power draw of 6.4/5.2 Watts. With peak sequential read/write speeds of 197/183 MBps and peak 4k read/write speeds of 1.17/2.19 Mbps the 3TB DT01ACA300 achieves an effective speed of 143 MBps which places the DT01ACA300 amongst the top handful of 3TB drives. Pricing of the DT01ACA300 is also very aggressive which makes the DT01ACA300 a superb value proposition. Comparing the DT01ACA300 and Barracuda shows that the DT01ACA300 is marginally faster but also slightly more expensive. [Nov '14 HDrivePro]

The 1TB Seagate Barracuda 2016 (ST1000DM010) has an impressive performance profile. With Sequential read/writes averaging 173 and 159 MBps respectively, the Barracuda can make short work of even moderately large backups. The small file (4K) performance profile is less impressive but still adequate with average read/writes coming in at 0.87 and 1.53 MBps respectively. For use as OS drives, rotational disks are quickly loosing market share to SSDs which offer orders of magnitude faster 4k read/write speeds. On the other hand cheap TLC based SSDs often have slower sustained write speeds than their rotational counterparts. Reasonably good overall performance can be achieved by using a TLC SSD to host the OS and a larger rotational drive such as the Barracuda for backups and media files. Larger capacity variants of this drive offer both better performance and better value for money. [Feb '17 HDrivePro]
