The 1TB Toshiba DT01ACA100 is a 3.5" desktop hard drive. With a rotation speed of 7,200 RPM and peak/idle power consumption of 6.4/3.7 Watts the DT01ACA100 is a reasonably power efficient desktop drive. The DT01ACA100 has peak sequential read/write speeds of 175 MBps and peak 4k read/write speeds of 0.76/2.06 MBps. These figures produce an overall effective speed of 132 MBps which places it around the middle of the 1TB pack in terms of typical consumer performance. The larger capacity variants of this drive are both faster and offer better value for money[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]


Hard Drive Rankings (Price vs Performance) July 2017 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.
