Alex Schepeljanski of Alex Intelligent Software develops the free AS SSD Benchmark utility for testing storage devices. The AS SSD Benchmark tests sequential read and write speeds, input/output operational performance, and response times. Because this software receives frequent updates, Benchmark Reviews recommends that you compare results only within the same version family.
Beginning with sequential read and write performance, the Seagate Momentus-XT Solid State Hybrid Drive produced 104.38 MB/s read speed, and 101.88 MB/s write performance. The sequential file transfer speeds have traditionally been low with this benchmark tool, which is why we will concentrate on the operational IOPS performance for this section.
Single-threaded 4K IOPS performance delivers 0.59 MB/s read and 0.98 MB/s write, which is average for notebook hard disk drives. Similarly, the 64-thread 4K reads recorded 1.29 MB/s while write performance was 0.73... indicating that AS-SSD was not optimized within the SSD cache of this Hybrid hard drive.
Displayed in the chart below, the 64-thread 4KB IOPS performance results for several enthusiast-level storage products illustrates which products offer the best operation under load:
Adaptive Memory Technology Notice
The Seagate Momentus-XT Solid State Hybrid Drive employs a proprietary Adaptive Memory technology that improves application performance matching the highest usage patterns. In most cases, benchmark performance tools do not activate the hybrid SSD features of this storage device.
In the next section, Benchmark Reviews tests transfer rates using ATTO Disk Benchmark.
