What does input/output operations per second (IOPS) mean?
And what is the background and performance characteristics of it?
If you want to know, then this post from MiniTool is what you need.
you could know many things about it in this post.
IOPS Definition
What is IOPS definition?
IOPS is short for input/output operations per second.
After got the IOPS meaning,MiniToolwill introduce its background and performance characteristics.
Since response time and workload are not specified at the same time, IOPS is essentially meaningless.
In addition, especially when testing SSDs, preconditioning considerations must be considered.
IOPS Performance Characteristic
Sequential operations and random operations are the most common performance characteristics measured.
As the number of outstanding IOs (queue depth) increases, the performance of some HDDs will improve.
Most commoditySATA drives cannot do this, or their implementation is too poor to see performance advantages.
Enterprise-grade SATA drives will increase by nearly 100% when the queue is deep.
High-endSCSIdrives, which are more common in servers, usually show greater improvement.
This results in hardware test sites providing independent measurement results when testing IOPS performance.
Newer flash SSDs (such as the Intel X25-E) have much higher IOPS than traditional HDDs.
Even if the random IOPS drops after 50 minutes, X25-E still has higher IOPS than traditional hard drives.
