Seagate Backup Plus 1 TB External HDD Review
DiskSpeed32
Contents
DiskSpeed32 is a hard disk drive benchmarking program that makes a read test of the entire drive, thus taking a long time.
The graph below shows the burst read speed for each tested hard disk drive, in kB/s.
It seems like the speed around 193 MB/s is a limit for the USB 3.0 interface we used, since both the external drives achieved this value. Internal drives achieved higher burst speeds.
The next graph shows the maximum sequential read speed for each tested drive, in kB/s.
In this test, the Seagate Backup Plus achieved a result about 12% higher than the Toshiba Canvio 3.0. The maximum sustained transfer rate was between 5% and 10% below the values we saw with the internal drives.
The following graph shows the average transfer speed in kB/s.
In this test, the Seagate Backup Plus performed nicely, achieving an average transfer rate 12% higher than the Toshiba Canvio 3.0 and between 4% and 7% higher than the numbers achieved by the internal drives we tested.
