Disk I/O is input/output (write/read) operations on a physical disk (or other storage). Requests which involve disk I/O can be slowed greatly if CPUs need to wait on the disk to read or write data. I/O Wait, (more about that below) is the percentage of time the CPU has to wait on disk.
What is disk IO?
Disk I/O includes read or write or input/output operations (defined in KB/s) involving a physical disk. In simple words, it is the speed with which the data transfer takes place between the hard disk drive and RAM, or basically it measures active disk I/O time.

جڏهن اسٽوريج I/O ۾ هڪ قطار آهي، توهان عام طور تي ويڪرائي ۾ اضافو ڏسندا. جيڪڏهن اسٽوريج ڊرائيو I/O درخواست جو جواب ڏيڻ لاءِ وقت وٺي رهي آهي، پوءِ اهو ظاهر ڪري ٿو ته اسٽوريج جي پرت ۾ هڪ رڪاوٽ آهي. هڪ مصروف اسٽوريج ڊوائيس پڻ سبب ٿي سگهي ٿو ته جواب جو وقت وڌيڪ آهي.
What is IO usage?
What Is Web Hosting I/O Usage? The web hosting I/O usage refers to the disk input and output (I/O). The disk I/O speed specifies how fast the website or scripts are allowed to carry out the input and output operations per second on your hosting server. Therefore, when it comes to the I/O range, the more the better.
What is IO bottleneck?
An I/O bottleneck is a problem where a system does not have fast enough input/output performance. I/O bottlenecks can be caused by various things and require various solutions. Systems analysts must look closely at where the problem is and try to determine why users may be experiencing slower rates of I/O.

What is disk performance?
Disk performance is measured by “total job completion time” for a complex task involving a long sequence of disk I/Os. The time for a disk drive to complete a user request consists of : command overhead. seek time. rotational latency.

How do I increase disk IOPS?
To increase the IOPS limit, the disk type must be set to Premium SSD. Then, you can increase the disk size, which increases the IOPS limit. Resizing the OS disk or, if applicable, the data disks will not increase the available storage of the virtual machine of the firewall; it will only increase the IOPS limit.
What is IO limit?
I/O is short for “input/output.” In the context of a hosting account, it’s the “throughput” or speed of data transfer between the hard disk and the RAM. … Unlike some other limits, you don’t “exceed” your I/O limit and it doesn’t generate errors.
What is I O bandwidth?
I/O bandwidth usually refers to a specific I/O device, but sure you could talk about possible aggregate I/O bandwidth over all PCIe links that connect the CPU to the outside world e.g. from multiple video cards, 100G NICs, and/or SSDs.
