About M.2 solid state drive (SSD)

M.2 SSD is a solid state drive, known as the Next Generation Form Factor (NGFF), which is especially designed for small devices like Ultrabooks or Tablets. Here are some features of it.

  1.  Has smaller size, high-performance, lower consumption.
  2. More flexible to use with many board size options.
  3. Support PCIe, SATA and USB interface.


Why clone M.2 SSD to M.2 SSD drive?

Here are 3 main reasons in the following why do you want to clone M.2 SSD to another M.2 SSD.

  1. Get larger capacity. Typically, the brand computers will install an M.2 SSD drive as boot disk, however, it will be filled up eventually after a long time use. So you may want to clone M.2 SSD to larger M.2 SSD drive to expand disk space.

  2. Get better performance. You may find that your computer run smoothly at first, but it will get slower and slower after a period of time. That is because your computer does not have enough space and you need a bigger M.2 SSD.

  3. Replace the damaged disk. Owing to many unexpected error, such as, virus, hardware failure, your disk may be corrupted. In this situation, clone failing hard drive to prevent data loss and replace the old disk with the new one could be the best choice.

Then, you may want to know which is the best free M.2 cloning software? Please keep reading to learn more.
