Google Chrome is currently the most popular browser on the market, but more users reported issues with it.

One of the more common problems is 100% disk usage in Chrome, and in today’s article, we’re going to show you how to fix his problem.

How do I fix 100% disk usage in Chrome?

1. Consider switching to a different browser

If you’re having issues with Chrome, perhaps this is a good time to consider using a different web browser.

Opera, for instance, is a multi-platform web browser, available on all desktop and mobile platforms, and it’s a great Chrome alternative.

It’s built on the Chromium engine, and it can work with Chrome extensions without problems if you’re a fan of Google engine.

Due to the fact that it incorporates plenty of efficient features, Opera has low resource usage, so you won’t have to deal with high RAM or disk usage.

It’s worth mentioning that the browser has some features that make it stand out in comparison to Chrome: built-in ad blocker, crypto-currency wallet, tracking protection, pop-out video player, and free unlimited VPN for extra privacy.

Lastly, Opera has a built-in messenger integration with most social media platforms, so you can chat or keep an eye on your feeds at all times.
