I know we have a lot of storage nuts on the STH forums. 1 million IOPS used to be something that was a big number. These days, 1 million IOPS is fairly easy to attain.
How to see if your storage is part of the club:
How to see if your storage is part of the club:
- FIO, IOMeter or another common benchmarking tool. Best practice is to do a heavy write pre-conditioning workload to get the drives to steady state.
- As an example, use IOMeter 4K Random Read (100% read 100% random) on drives. For today's NAND NVMe drives you will need to pump up the QD to a high enough number (often QD128 or QD256) to reach peak performance.
- Post system specs and screenshots of your entries to this thread. If you want, system price and date acquired are also good figures to have.
- Download and extract Iometer 1.1.0
- Download and extract STHiometer zip for example read tests (note this does NOT have the pre-condition workloads)
- Run Iometer as administrator
- Delete the default Manager
- Open the STHiometer4k128kRead.icf profile from Iometer
- Add a manager
- Use 4 workers per disk (e.g. for 1 drive being tested you would have 4 workers, for 4 drives you would have 16) and ensure they are setup.
- Select a file name that is descriptive to save
- Get over 1 million IOPS (if you want the dashboard picture you can go to Results Display and click the > character on the right side to bring that view up.)
- If you want to speed things along, for NVMe NAND SSDs you will want to try tests 6, 7 and 13, 14 of 14 as those will effectively be at QD128 and QD256. For SATA SSDs you will want to look around test 3 and 4, 10 and 11. For lower QD figures. You can use the "next" button on the dashboard page to move to the next QD test.
