OCZ Vertex 3.20 240GB SSD Review
Chris Hadley / 11 years ago
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.
The Vertex 3.20 has a rated random read IOPs of 35k, yet after repeated testing we were able to obtain results of double that – closer to the rated sequential IOPS of 90k.
Whilst the write IOPS are not as high as the read, they are very close to the rated 65k that OCZ specify.
