Why mirror hard drive to SSD?

Many people would like to mirror their hard drive to a larger disk when there’s no sufficient storage space. But nowadays, people usually mirror their hard drive to an SSD. How come since we all know an SSD is generally smaller than an HDD at the same price? You’ll understand why to do it in the following contents.

● It protects you from data loss. There’re many causes of data loss during computer use. However, if you’ve already mirrored the hard drive to an SSD, then, you won’t run into this trouble since you can easily restore your data from the mirrored SSD.

● It can upgrade and speed up your PC. No matter desktop or laptop users, you all want it to run fast. Well, the SSD is more stable and runs faster than HDD. If you want to upgrade your PC, replacing HDD with an SSD is a good way to upgrade and speed up your PC - you can upgrade HDD to SSD without reinstalling OS and programs in this way.

The software for mirroring hard disk to SSD

It’s never easy to mirror a hard drive to an SSD as you cannot just copy everything from one disk to another which is likely to cause severe data loss and prevents you from booting from the destination disk if you mirror the system. So, here, a third-party software utility will be introduced to help mirror hard drive to SSD in Windows 11, 10, 8, 7.

AOMEI Partition Assistant Standard is such a great HDD and SSD clone software utility that you can use to clone hard drive to SSD. Its “Disk Clone Wizard” allows you to clone HDD to SSD, or clone a hard drive to another hard drive in a few simple mouse-clicks. What’s more, you can repartition hard drive during HDD to SSD clone so that you can use the SSD directly after clone.

How to mirror hard drive to SSD step by step?

Here we will show you how to mirror a hard drive to SSD without reinstalling OS and losing data.

What you should prepare in advance:

A computer installed Windows OS. Here, the computer installed a hard drive with Windows OS. AOMEI Partition Assistant works on Windows all editions of 11/10/8/7/Vista/XP. The hard drive with Windows OS is the drive you are going to mirror.

A solid-state drive. This solid-state drive is the drive you’ll be mirroring to. The SSD should be equal to or larger than the source drive’s used space.

 Check bad sectors on the destination hard drive. You can’t boot your computer from an SSD with bad sectors. So, you’d better first check whether there're bad sectors and repair the hard drive if there're with some third-party bad sector repair software.

Make a backup of the HDD. If you don’t want to lose any data during the disk clone, then, make a backup first so you can restore the computer to the previous state when something unexpected happens. 

Back up the SSD data. The content in the target disk will be deleted during the operation. If there is any important data on the target disk, back it up first.

USB-to-SATA adapter. If what you have is a laptop with only one hard drive bay, then, it’s necessary to get a USB-to-SATA adapter.
