Seagate SSHD 2TB Solid State Hybrid Drive Review

IOmeter, HD Tach & PC Mark 8

IOMeter is an I/O subsystem measurement and characterization tool for single and clustered systems. It is used as a benchmark and troubleshooting tool and is easily configured to replicate the behavior of many popular applications. One commonly quoted measurement provided by the tool is IOPS.

IOMeter allows the configuration of disk parameters such as the ‘Maximum Disk Size’, ‘Starting Disk Sector’ and ‘# of Outstanding I/Os’. This allows a user to configure a test file upon which the ‘Access Specifications’ configure the I/O types to the file. Configurable items within the Access Specifications are Transfer Request Size, Percent Random/Sequential distribution, Percent Read/Write Distribution, Aligned I/O’s, Reply Size, and TCP/IP status among others.

PCMark 8

PCMark 8 Storage benchmark is used test the performance of SSDs, HDDs and hybrid drives with traces recorded from Adobe Creative Suite, Microsoft Office and a selection of popular games. You can test any recognized storage device, including local external drives. Unlike synthetic storage tests, the PCMark 8 Storage benchmark highlights real-world performance differences between storage devices.

The PCMark 8 result really shows that an SSHD can make a difference with a result that’s over 50% better than a traditional mechanical drive.

HD Tach

HD Tach is a program that tests the sequential read, random access and interface burst speeds of the attached storage device (hard drive, flash drive, removable drive etc.). Drive technologies such as SCSI, IDE/ATA, IEEE 1394, USB, SATA, and RAID are all supported.

Version 3.0.4.0 is sadly the final version and the software has reached its end-of-life support. It’s still a nifty benchmarking tool and it can’t hurt to include it in our tests.
