The next software we used was the ATTO Disk Benchmark. The tool measures storage systems performance with various transfer sizes and test lengths for reads and writes. The benchmark performs file transfers ranging from 0.5 KB to 8192 KB. ATTO can be adjusted to do overlapped I/O, in a variety of queue depths. We tested the HDD using the benchmark's default settings, using 256KB file length performance and QD4. ATTO probably gives the most accurate results for compressible read and write data.

The writing performance of the drive was almost steady at around 116 MB/s for files bigger than 8KB. Reading was also solid at 116-117 MB/s with files bigger than 8KB:

We proceed to IOMeter benchmark. Iometer is run by using workstation and database patterns for queue depths (outstanding I/Os) of two and 32, representing very light and moderate loads. Iometer is both a workload generator (that is, it performs I/O operations in order to stress the system) and a measurement tool (that is, it examines and records the performance of its I/O operations and their impact on the system). The app's ability to bombard drives with an escalating number of concurrent IO requests also does a nice job of simulating the sort of demanding multi-user environments that are common in enterprise applications. It can be used for measurement of the performance of an HDD or SSD. We run the IOMeter tests using the Xtreme Benchmark template .

The drive logged just 97.57 combined IOPS; 65.29 read IOOS and 32.28 write IOPS.

Below you see the results of Futuremark's PCMark 7 Professional edition. The software includes 7 PC tests for Windows 7, combining more than 25 individual workloads. The Samsung HDD scored 1473 points:
