What size SSD do I need for windows 10?

Windows 10 has been out for a while now. One of the best ways to speed up your computer is to install Windows on an SSD drive. The SSD will provide you with increased booting speeds, faster application loading times, and better responsiveness when switching between applications. However, SSDs are expensive and you do not want to purchase a unit that is too large or small. So how big SSD do I need for windows 10? Let’s talk.

The Windows 10 operating system has seven versions and except for Windows 10 Enterprise and Windows 10 Enterprise LTSC, all other versions (Windows 10 Home, Windows 10 Pro etc.) require a minimum of 16 GB of SSD space for 32-bit OS and 20 GB for 64-bit OS.

What bothers me most is not the version of Windows you’re running, but rather what files and data you plan to store on the drive. However, that’s not the intention of this article so let’s see what Microsoft recommended as minimum disk space requirements.

Windows 10 Enterprise LTSC16 GB for 32-bit OS, 32 GB for 64-bit OS

It should be noted that all of these versions have been replaced by their latest Windows 11 versions. if you see the above table you will realise that, for windows installation, 16 GB for 32-bit OS, 20 GB for 64-bit OS will suffice for most of the time. But there is one additional thing that you have to keep in mind, which is hibernation.

By default, Hibernate is enabled, and it will not cause your computer to break down, so it is not necessary to disable it if you are not using it. But hibernate reserves some disk space for its file (hiberfil.sys) which is allocated at 75 percent of your RAM. If you have 8GB of RAM, the hiberfil.sys file will occupy 6GB of your hard drive space, if you have 16GB of RAM, the hiberfil.sys file will occupy 12GB.
