To begin, 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 would increase the load speed greatly. Although a SSD is more expensive than a HDD now, you can buy a small one, which is comparatively cheap. 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 high speed of reading and writing.

If this is your first time to build a computer with SSD disk, then you can connect your SSD and install Windows on SSD drive directly. 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 complex command line or backup first then restore. But here I would like to recommend you the best way - using AOMEI Partition Assistant to realize SSD migration. This feature allows you to do SSD 4K alignment as well.

Migrate OS to SSD or HDD

Plug your SSD on your computer first. Download AOMEI Partition Assistant Professional Edition from the official website, install and open. Click “Migrate OS to SSD” from the left Wizards panel and click “Next ” in the pop-up window.

In this step, select an unallocated disk (SSD) and click “Next” to continue.

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, back to the main screen, click “Apply” to commit the changes.


Now you see, with the help of AOMEI Partition Assistant, setup SSD for OS only becomes much easier. Be sure to free up SSD disk space every a couple of months to ensure fast running speed. You can perform lots of partition optimization operations with this software. Practical feature: move partition, delete all partitions, split partition, extend partition, etc. It is safe to use and won’t cause data loss.

With the popularization of Windows 8, you can use AOMEI Partition Assistant to create a portable Windows 8 that boot from USB drive. That is “Windows to Go Creator”. You can also do a backup before transferring OS to SSD with AOMEI Backupper.
