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]
