To begin with, SSD stands for Solid State Drive. You should know that SSD is faster than HDD (Hard Disk Drive). So setting up SSD for OS only will drastically increase load speed. Although an SSD is more expensive than an HDD now, you can buy a small one, which is comparatively cheaper. For example, buying a 64 GB SSD and using it for OS only is enough. If you have enough budget, you can buy another SSD for games or other programs that need a high speed of reading and writing.

If this is your first time to build a computer with an SSD disk, then you can connect your SSD and install Windows on SSD drive directly. However, if you have installed OS on HDD before, and you want to optimize your computer. For example, transfer the operating system from HDD to SSD, but don’t want to reinstall the operating system. What do you do then? One way is doing it with a complex command line or backup first and then restore. But here I would like to recommend the best way - using AOMEI Partition Assistant Professional to realize SSD migration. This feature allows you to do SSD 4K alignment as well. Refer to the following tutorial.

Plug your SSD into your computer first. Install and open AOMEI Partition Assistant Professional. Click “Migrate OS to SSD” from the left Wizards panel and click “Next” in the pop-up window..

Here, you can resize partition and change drive letter as you wish. Type the value or directly drag to adjust.

After everything has been done, go back to the main screen, click “Apply” to commit the changes.



Now you see, with the help of AOMEI Partition Assistant, setting up SSD for OS only becomes much easier. After it’s done be sure to free up SSD disk space every couple of months to ensure the health of the system. Moreover, you can perform lots of partition optimization operations with this software such as moving partition, deleting all partitions, splitting partition, extending partition, etc.

With the popularization of Windows 10, you can use AOMEI Partition Assistant to create a portable Windows 10 that boot from USB drive. That is “Windows to Go Creator”. You can also make a backup before transferring OS to SSD with AOMEI Backupper.
