Overview of moving Windows to SSD without reinstalling OS

Windows operating system keeps speeding up the booting time and currently Windows 10 is able to boot within a couple of seconds. Booting time will be faster if Windows 10 is installed on an SSD and overall computer performance will be better if both Windows OS and programs are installed on an SSD. SSD is a kind of new storage device which gains great popularity these days. Being different from traditional hard drives, SSD contains no moving parts and it stores data on flash memory. The visible difference between SSD and HDD lies in that SSD has faster speed of reading and writing data, which should thanks to that SSD doesn’t use rotating platters nor moving headers. Besides, SSD is more reliable and makes less noise.

Which is the easiest way to replace the internal hard drive which install Windows OS and applications? We’d like to recommend system migration. System migration refers to the process of moving / transferring system partition (usually C drive) and other system booting related partitions (such as MSR partition, ESP partition) to another HDD or SSD so that users do not have to reinstalling everything! Such a process is popular among users who want to upgrade computer by way of replacing old hard drive with an SSD and do not want to (or do not know how to) reinstall OS.

Why do we need to move Windows to SSD?

Moving Windows to SSD is the process of migrating operating system from HDD to SSD. Some users might be puzzled that why we need to move Windows to SSD. Here we sum up reasons in two aspects.

On one hand, we can get better performance. SSD is much faster than mechanical hard drives, thus system booting time and data accessing time will decrease immensely after moving OS to SSD. For example, Windows 8 boots from SSD within 10 seconds.

On the other hand, many of us must have met the problem that system partition reports low disk space problem. Such issue will pose bad effect on computer performance. If this problem is not solved, then you’ll face risk of system corruption. Thus, system should be installed to partition that provides enough capacity. As technology advanced, the price of SSD is affordable to many users. It’s good choice to add an SSD to computer and move Windows to it.
