I have a copy station which takes two hard drives and have found it easy to use and reliable. The only drawback I've noticed concerns the relative sizes of the two drives. There's no problem copying from a small hard drive to a larger or equal sized SSD drive. You can then use software to rearrange and resize partitions. However, if you have a large hard drive and want to copy to a smaller SSD drive it's not possible. Mind you it is a few years since I bought my copy station so that may have changed.
