DiskSpeed32 is a disk drive benchmarking program that makes a read test of the entire drive, thus taking a long time.
The first graph compares the average access time (in milliseconds) measured by DiskSpeed32.
In this test, the Laptop Thin SSHD performed more like an SSD, not showing the typical value for a hard disk drive.
The graph below shows the burst read speed for each tested hard disk drive, in kB/s.
In this test, the speed of the SATA-600 interface is crucial. The Seagate Thin SSHD performed 51% faster than the Hitachi Z5K500-500 and 65% faster than the Seagate ST500LM012, both with SATA-300 interface, but 14% slower than the Seagate Barracuda 7200.12.
The next graph shows the maximum sequential read speed for each tested drive, in kB/s.
In this test, the Seagate Laptop Thin SSHD outperformed all other disks, being 4% faster than the Barracuda 7200.12, and 11% faster than the Seagate ST500LM012.
The following graph shows the average transfer speed in kB/s.
In the average speed test, the Seagate Laptop Thin SSHD presented the same performance of the Hitachi Z5K500-500, was 8% faster than the ST500LM012, but 14% slower than the Barracuda 7200.12. As this test measures the average read speed of the entire disk, it is expected that the SSD cache wouldn’t make a difference.
