GPT Disk Knowledge
GPT stands for Globally Unique Identifier (GUID) Partition Table, which is a standard for the layout of the partition table on a physical hard disk. GPT is gradually replacing the old MBR (Master Boot Record) standard, which has some limitations that only supports hard disk up to 2TB in size, and up to four primary partitions.
GPT supports hard drive lager than 2TB and Windows can only boot from GPT on a UEFI-based computers. Unlike MBR, GPT hard disk allows you to create primary partitions up to 128 due to system limitation. So far, the most current computers support GPT standard, which is compatible with MBR. In addition, GPT disks only support 64-bit Windows system while MBR disks support both 32-bit and 64-bit Windows system. However, why it's necessary to clone GPT disk to smaller SSD drive?
Why Clone GPT Disk to Smaller SSD?
Compared with HDD, SSD is more reliable than traditional hard drive (HDD) due to its features, durability, faster speed, easy to carry, and no noise while working. Besides, the capacity of SSD drive typically smaller than HDD, is 128GB, 256GB, 512GB, 2TB, etc. Thus, if you have a GPT disk, you may want to clone GPT hard drive to SSD, usually a smaller SSD to get a better performance, shorter boot time, etc.
GPT Disk Cloning Software
How to clone GPT disk to smaller SSD without installing Windows and applications? First of all, make sure what kind of SSD you can use in your computer. Then prepare some extracting tools and disk cloning tool. To clone GPT HDD to SSD successfully, you’d better look for a cloning software with better comprehensive performance.
AOMEI Backupper Professional is a powerful backup and cloning software for popular personal Windows operating system, like Windows 7, 8, 10, etc. It’s highly recommended by users due to its versatility, reliable execution capability, and intuitive interface. Its main features include transfer OS to another hard drive or SSD with system clone, synchronize files to another location with File sync, backup system, partition, disk to external hard drive, SSD, USB flash drive, NAS device, network share and so on. And this software supports MBR and GPT disk, dynamic disk, hardware RAID, UEFI boot mode, etc.
How to Clone GPT Disk to Smaller SSD in Windows 7/8/10?
In the first place, you could download AOMEI Backupper Professional to have a try. Here is how to clone GPT HDD to smaller SSD:
Step 1. Connect the smaller SSD with your computer. Install and launch AOMEI Backupper Professional, on the main interface, select “Clone” > “Disk Clone” in turn.
Step 2. Choose your GPT disk as source disk to clone, and press “Next”.
Step 3. Select the smaller SSD drive as the destination disk to save data from GPT HDD, then hit “Next”.
Step 4. Check “Align partition to optimize for SSD”, and click “Start Clone” if you have confirmed the operation.
After a few minutes, cloning GPT/UEFI disk to SSD will be soon completed. And the cost time will depend on the data size on GPT hard drive. Besides, AOMEI Backupper Pro allows you to create WinPE bootable media to boot your system after cloning, create PXE boot tool, incremental and differential backup, full backup and more.
