What is Disk I/O Speed?

Disk I/O speed determines how fast your websites, emails, and scripts are allowed to perform read/write operations on the server. More is usually better, but not always.

When a visitor visits your website or you send/receive an email, your hosting performs data read/write operations on the server.

Providing higher Disk I/O is expensive. Most providers don't allow more than 1 MB/s Disk I/O on their servers.

It will not matter how much storage, bandwidth, CPU, or RAM you have. If you are set to a low I/O speed, your websites and scripts will perform slower. A slow hosting may also lead to data loss and poor email communication.

We use powerful NVMe SSD, which grants an abundance of Disk I/O speed on our servers. We pass this benefit on to our users without charging them anything extra. As a result, your websites and scripts will run faster and gain higher search engine rankings on Google and other search providers.


Does higher disk I/O always improve performance?


It is important to note that having more disk I/O than your website needs will not further increase your performance. It can be counterproductive and create risks of performance degradation.

Malicious actors can take advantage of overly generous disk I/O limits, which can degrade performance for all users on the server. The provider will need to spend more server resources to monitor and prevent their actions if they provide more disk I/O than is necessary.

Malicious actors are always on the hunt to find new ways to exploit the server by taking advantage of malicious techniques, zero-day vulnerabilities, poorly written scripts, and overly generous resource allocations. Some WordPress plugins and themes, for example, are common sources of poorly written and malformed scripts.

This is why it is essential to find the balance instead of overly increasing the disk I/O limit so that the server can spend more resources to boost website performance instead of fending off attacks.
