Kingston SSDNow V300 120GB SSD Review

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 behaviour 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
• TCP/IP status
• Burstiness.

Starting off with the read IOPs we find that the results we achieved are virtually bang on the mark with what Kingston specify the drive will offer, with results topping out at just over 1k under the rated 85k.

In a similar fashion to the read IOPs, the write IOPs are also right on the mark with where Kingston specify. In our tests, the drive even went slightly over the rated 55k.
