What is disk clone or system clone?
In computing, clone is a method of replicating every bit of information from one place to another and making the source and the destination exactly the same. There are two types of clone when it comes to upgrading hard drive: disk clone and system clone. What are they?
As their names refer, disk clone is the process of copying the entire disk. All data saved on the drive will be transferred, including the operating system, applications, drivers and personal files. System clone copies only the system partition and system-related partition(s). All information that is necessary for system to run in the destination location will be transferred, and so will other files you store on system partitions.
Now you see the difference between disk clone and system clone is to clone either the entire disk or particular partitions. Then, how to choose between them?
System clone vs disk clone: how to choose between them
To choose from disk clone and system clone, you may take following things into consideration:
1. The contents you want to transfer
If you want to get an exact copy of the original drive, then choose disk clone. If you only want to use the old operating system on the new drive, then pick system clone.
2. The capacity of the destination disk
When cloning a larger disk to a smaller disk, you should make sure that the destination disk is big enough to hold all data saved on the source disk if you use disk clone. Sometimes you have to use system clone due to the capacity limitation.
System clone or disk clone? That depends on your demands and how many data your destination disk can hold. As there’s no built-in cloning utility in Windows, you may look for reliable third-party cloning software.
All-in-one cloning software in Windows - AOMEI Backupper
AOMEI Backupper Professional, powerful cloning software for Windows 10/8.1/8/7/Vista/XP, offers both Disk Clone and System Clone features. Wanna know AOMEI Backupper Disk Clone vs. System Clone? Please read on.
Now let’s learn detailed steps of performing disk clone and system clone via AOMEI Backupper. Take cloning to an SSD as an example:
◈ Connect the target SSD to your computer and make sure it is detected.
◈ Backup files on the destination SSD, because the target drive will be overwritten during the cloning process.
Case 1: Clone HDD to SSD via AOMEI Backupper
1. Install and run AOMEI Backupper. Click “Clone” on the left pane and select “Disk Clone”.
2. Select the current disk as the source disk and the SSD as the destination disk successively.
3. Tick “SSD Alignment”. Confirm the operation and click “Start Clone”.
- Sector by sector clone: it will clone every sector on the source disk no matter it is used or not, which requires the destination disk to be equal to or larger than the source disk.
- To get the best performance from the cloned disk, it's suggested to clone Windows 10 to NVMe SSD. Because it has the fastest transfer speed.
- Besides HDD to SSD cloning software, it is still an M.2 SSD cloner. Thus, you can use it to clone M.2 SSD to M.2 SSD, migrate Windows 10 to M.2 SSD, etc.
Case 2: Migrate OS to SSD using AOMEI Backupper
1. Launch AOMEI Backupper. Click “Clone” and select “System Clone”.
2. The required system partition(s) is (are) selected by default. Select the partition on the connected SSD as the destination path and click “Next”.
3. Tick “SSD Alignment” and click “Start Clone”.
