Overview
Every time your website updates — whether it’s a customer submitting a form, uploading a file, or placing an order — the server needs to write that information to storage. The speed at which this happens is called IO Write Bandwidth.
Think of it as your website’s writing speed. The faster it is, the quicker updates are saved and confirmed. Without enough write bandwidth, your website may feel slow when handling new content, customer uploads, or database transactions.
