From O&O Software:
O&O SSD Migration Kit enables an easy and convenient migration of your partitions from conventional hard drives to SSDs. This leads to the creation of a duplicate of the selected drives on the SSD or on a drive of the SSD. If a partition or an entire hard disk is duplicated on a SSD, the partitions need to be adapted and aligned to the structures of the SSD. If this doesn't happen, the SSD is simply overwritten with information from the old hard drive and the misalignment of the partition might cause a performance loss of up to 50%. In addition, the life span of the SSD is shortened, since you now save new data on the SSD, which needs more space than necessary in deleting and rewriting than normally.
