HD Tune Pro
Now we will look at the results recorded using HD Tune Pro.
In the burst speed test, none of drives took advantage of the speed of the SATA-600 interface. The Seagate Desktop SSHD 2 TB was 8% slower than the Barracuda 2 TB.
In the average read speed, however, the Desktop SSHD 2 TB was 7% faster than the Barracuda 2 TB.
Access time is another important measurement. It measures the time the storage device delays to start delivering data after the computer has asked for given data. It is measured in the order of milliseconds (ms, which are equal to 0.001 s); the lower this value, the better.
In this test, the Desktop SSHD actually recorded an average access time compatible with SSD units, while the Barracuda showed a typical access time for mechanical drives, being 6441% slower.
