Disk I/O speed determines how fast your websites, emails, and scripts are allowed to perform read/write operations on the server. The more, the better.
When a visitor visits your website, or you send/receive an email, your hosting performs data read/write operations on the server.
If you are set to a low I/O speed, your websites and scripts will perform slower. It will not matter how much storage, bandwidth, CPU, or RAM you have. A slow hosting may also lead you to data loss and poor email communication.
Providing higher Disk I/O is expensive. This is why most providers don't allow more than 1 MB/s Disk I/O on their servers.
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.
