Why need to clone HDD to SSD?

Both SSD and HDD are computer storage devices. However, more and more users would like to use SSD instead of HDD. Why?

HDD, hard disk drive, is the traditional storage device with metal platform. you have to put up with the noise of HDD's spinning. HDD is widely used in the past years. But it is kind of out-dated device for today's demand for running speed.

SSD, or solid state drive is the new generation of storage device. It stores data with a little chips without the voice of platform spinning. As it is read and written with the chips, the speed is much faster than HDD. Thus lots of people would like to have an SSD to replace HDD.

When you have a new SDD, you may still want to keep the data on the HDD, so you can clone HDD to SSD, which will move all data, settings, software, pictures, videos, to the destination drive. and you don't need to reinstall applications and software.

What is SSD alignment?

The SSD partition alignment is for optimize the performance of the SSD. Although an SSD reads and writes data with fast speed, sometimes, some people find the speed is not fast as their expected. This is because the SSD is never aligned.

As we known a partition can be divided into lots of sector, and one sector usually is 512 bytes. It had worked very well for a while. But nowadays, many manufacturers take sector size of 4096 bytes to produce SSDs. And the 4096 bytes sector is called as “physical sector”.

But on the other hand, systems and software don't adapt to the sector change. They still retrieve and report data as it is an 512 bytes disk. and we call it logical sectors.

Thus you can find the situation where the logical sectors and physical sectors are not aligned. The operating system has to over least one sector to read data. this is the read why the SSD is not fast as the manufacturers claimed.

Misaligned Partition

How to clone HDD to SSD and align SSD partition?

So when you have a new SSD, it is important to choose a cloning software that support SSD alignment partition. Otherwise you can't get the performance you want

Here we highly recommend you AOMEI Partition Assistant, which can not only migrate OS from HDD to SSD, but also can copy all data on the HDD to SSD without reinstalling software, meanwhile, it will optimize the SSD during the cloning process. Besides, it supports cloning larger disk to a smaller SSD, after all the SSDs are more expensive than HDDs with the same capacities.

Step 1. Install and launch this freeware, plug click Disk Copy Wizard at the left pane.

Step 2. It will guide you to copy the whole disk. Select “Copy Disk Quickly”. The “Sector-by-Sector Copy” will copy all sectors of the disk to a target disk no matter it is used or not, so it would take a larger space and more time.

Step 3.Here you need to choose the source disk. Select disk 1.

Step 4. Then, select the SSD you plugged in before as the destination space. Here you need tick the box marked as red so that the SSD would be optimized. It will clone HDD to SSD and perform SSD alignment.

Step 5. You can adjust the partition size on the SSD here. Click Next.

Step 6. After all the settings, in the main interface, click "Apply" > "Proceed".

Boot from the cloned SSD

After cloning, just replace the HDD with the SSD, you can directly boot from the SSD. And if you want to keep the HDD to store data, you might need to enter BIOS to set the boot device.

1.Restart your computer and long press Esc, F1, F2, F8 or F10 during the initial startup screen.

2. Choose "Boot" tab in the BIOS utility, and move the cloned SSD to the top on the listed devices.

3. Save the setting, and your PC will be started from the SSD.

Conclusion

With a few steps, you can easily clone HDD to SSD and slign the SSD partition without reinstalling. whether you are using Windows 10, 8, 7, XP, Vista, this cloning tool can perform well. And AOMEI Partition also provide many other features for disk management. For example, if you want to abandon the HDD, or give it to others, you can use it to wipe the hard drive to prevent data leakage.
