If you’re a Windows user and you’ve noticed your computer isn’t as fast as you’d like, then you might want to look out for this one setting that could be slowing it down.

When things start to slow down on your computer, it can often be attributed to its solid-state drive (or SSD).

The SSD is one of the key components when it comes to determining how responsive your computer is, so if it starts to take longer to carry out simple tasks, this could be the culprit.

However, it’s not always the cause, and if your computer is feeling sluggish, it might be down to a hidden Windows setting, rather than the SSD.

This Windows setting might be why your computer feels slow

Modern SSDs have a temporary storage area, known as a cache, that helps them to write data faster. 

So, when you save something on your computer, the data will go to the cache before then quietly moving to slower permanent storage in the background. 

Your computer will treat saving data in one of two ways: 

  • A safe mode, which Windows calls Quick Removal, that only considers data saved after it’s written to permanent NAND storage
  • A fast mode, which Windows calls Better Performance, where it’s considered saved as soon as the data hits the cache. 

On a large single file, like an entire movie, you usually won’t notice any difference, but problems can arise when the computer is having to make lots of tiny saves all the time, for example, with app installs and updates, general browsing, and temporary files. 

These small tasks can make your computer run more slowly, but there’s a Windows setting that could help. 

To find it, you’ll need to open up  Device Manager and then find Disk Drives and find the drive you need. 

Right-click on the driver and choose Properties, then click into the Policies tab. Here, you’ll find Quick Removal (default) and Better Performance – if it’s not selected, choose Better Performance.

With this option selected, you should find a more aggressive change to your laptop’s caching behavior, which should help to speed things up.

But it does come with a bit of a caveat

While switching out the setting will make your computer go a little faster, it does come with a bit of a warning. 

According to makeuseof.com, Quick Removal is designed to prevent data loss if your computer loses power before it has been written from the cache to the long-term memory storage. 

So, by turning it off in favor of Better Performance, you run the risk of losing data before its had a chance to save properly. 

On a desktop computer, the chance of this happening is fairly low, but if you’re using a Windows laptop that could run out of juice while you’re using it, it’s something to consider before switching.
