Overview
Every time someone clicks on your website — whether to load a page, open a product image, or download a file — the server must read data from storage and deliver it instantly. The speed at which this happens is called IO (Input/Output) Read Bandwidth.
Think of it like the water pipe that connects your storage to your visitors. The wider and faster the pipe, the quicker your website can deliver data. Without enough IO bandwidth, even a well-designed site may feel slow or unresponsive.
