QNAP TS-259 Pro Turbo NAS
Mar 1st, 2010 | By SimonIOMeter is an I/O subsystem measurement and characteristic tool for single and clustered systems initially designed by Intel.
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). It can be configured to emulate the disk or network I/O load of any program or benchmark, or can be used to generate entirely synthetic I/O loads. It can generate and measure loads on single or multiple (networked) systems.
I configured IOMeter to create a 1GB file on the target device, TS-259 Pro, and it will pull the performance of 5 minutes and report back the average transfer rate for various block size recordings. The results are 100% sequential followed by 100% random.
Much like the results from the Intel NAS Performance Tests, the performance differences between the three disk configurations were very small. For a 1GB file, the results are lower than what was reported by IOZone but not far from what would be considered overly slow or lightning fast for a NAS. I can’t explain why the random read results for RAID 1 were incredibly high. My guess would be some bizzare cache effects or just the software going nuts, I ran this benchmark 5 times and the numbers were exactly the same.
