Why need to replace C Drive?
Generally, we install an operating system on the C drive, so it is a lot more important to keep it functioning well than other drives. But there are 3 circumstances where you need to consider replacing the small C drive.
▶ The C drive is too small to keep the PC running smoothly
C/system drive needs some free space to maintain its running. If your C drive is out of space, the Windows running speed will slow down and ask you to clean the disk.
▶ Upgrade the internal disk to a larger one
To have a better experience, you may want to change their HDD with a new SSD, meanwhile, you need to keep the same system environment, you can find a way to replace the system drive.
How to replace smaller C drive with SSD/HDD in Windows 10, 8, and 7?
Step 1. Choose a correct SSD/HDD
A solid-state drive (SSD) is better than a hard drive disk(HDD) to keep the operating system. Because SSDs use flash memory to write and read data giving a much faster-running speed than the traditional HDD. And they are more durable and safer to store system files and running programs.
However, given the price of SSDs is higher than HDD’s, you can also choose a larger HDD. Whatever drive you would like to select, first of all, you need to make sure the size of the disk has enough space to contain all the C drive data.
Another thing you need to consider is the interface for SSD. Interface standards of SSD include M. 2, PCIe, and SATA, which provide different performances. You need to know what type of SSD your PC supports. If you want an M.2 drive, there should be M.2 slot on the motherboard.
Step 2. Clone hard drive or C drive to SSD/HDD
The cloning process is a convenient operation to transfer system, data, applications, and settings to a new storage device. To replace a small C drive, you don’t want to reinstall system and applications, because it takes time and energy.
Here we recommend cloning software named AOMEI Partition Assistant Professional, which helps you to copy a hard drive to another SSD/HDD in Windows 11, 10, 8, and 7. There are 4 reasons why it is recommended to replace a small C drive:
• It supports all most Windows operating systems, like Windows 11,10, 8, 7, XP, and Vista. • It offers clone system partition or the whole disk functions, which give the choice to only replace the C drive or migrate the whole disk, including OS and other software and data. • It supports cloning larger disk to smaller SSD. On account of the high price of SSD, the source disk probably is bigger than your SSD. AOMEI Partition Assistant can clone successfully in this circumstance.
✍Before we start, you need to make some preparations:
◤ Get an adapter. you might need an adapter to connect the SSD with your PC when cloning. ◤ Back up files the destination SSD if it is not new. The cloning operation will format the SSD that will delete all file on the SSD. ◤ Install AOMEI Partition Assistant on your PC.
