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]


This drive can be used as a combined system and storage drive thanks to its fast 7200K rpm and enormous 3TB capacity. Recently prices for all large drives have been dropping and the 3TB Barracuda 7200.14 is currently a good choice in terms of both value for money and performance. Not only does the Barracuda have respectable sequential read/write speeds but it also goes head to head with the various green options, consuming a very reasonable 5.4W vs 5W (idle) on average for a "green" drive. That amounts to a tiny power consumption disadvantage and a lot more speed. Overall the Barracuda is priced aggressively and represents very good value for money. [Oct '12 HDrivePro]
