About the freeware

AOMEI Partition Assistant Standard is the freeware to help you clone HDD to SSD of different sizes successfully while keeping the best performance of the SSD by aligning partition:

SSD, with 4k size paralleled to 4k sectors, has a 4096 bytes or large internal memory page size. Sometimes the partitions created on SSD will be misaligned after users clone HDD to SSD, and the SSD has to read data across 4k sectors. In this situation, the time of the SSD to read or write will be increased, as a result, the system performance will be decreased.

Luckily, free AOMEI Partition Assistant Standard is able to align partition during cloning process so to keep the best performance of SSD, and operating system.

Besides, there are two copy methods which are insurances when you clone HDD to SSD of different sizes.

  • If you clone smaller HDD to larger SSD or SSD with the same size, you can do sector by sector clone which refers to clone all sectors of HDD no matter it is used or not so that you get a 100% identical copy and AOMEI guarantee the job success even there are blank sectors or logically bad sectors.

  • If you clone HDD to smaller SSD, you are allowed to clone only used space so to make a successful clone. Since there are both used and unused space on the drive, clone only used space will reduce the occupied space without cloning the unused space on drive.

Next, let’s see details of how to clone HDD to SSD different sizes with the freeware - AOMEI Partition Assistant Standard.
