What is disk latency?
Disk latency refers to the time delay between a request for data and the return of the data. It sounds like a simple thing, but this time can be critical to the performance of a system.
What is a good disk latency?
For hard drives, an average latency somewhere between 10 to 20 ms is considered acceptable (20 ms is the upper limit). For solid state drives, depending on the workload it should never reach higher than 1-3 ms. In most cases, workloads will experience less than 1ms latency numbers.

What is normal disk response time?
Response Time (ms).
Disk response time in milliseconds. For this metric, a lower number is definitely better; in general, anything less than 10 ms is considered good performance.
What is an acceptable latency?
Latency is measured in milliseconds, and indicates the quality of your connection within your network. … Anything at 100ms or less is considered acceptable for gaming. However, 20-40ms is optimal.

What is network latency?
Latency is a measure of delay. In a network, latency measures the time it takes for some data to get to its destination across the network. It is usually measured as a round trip delay – the time taken for information to get to its destination and back again.
What is IOPS limit?
IOPS (input/output operations per second) is the standard unit of measurement for the maximum number of reads and writes to non-contiguous storage locations. IOPS is pronounced EYE-OPS.
What is a good disk queue length?
A good rule of thumb is that there should never be more than half the number of spindles in the queue length. If you have a 10-disk RAID volume, the queue length should be less than 5.
