Why we need to align partitions on SSD?

Nowadays people who want to build-up a PC usually tend to purchase a solid state drive because the price of SSD has dropped a lot and it provides a much better user experience than traditional HDD. High-end laptops often adopt a two-disk scheme: one HDD and one SSD. The capacity of SSD is not as much as HDD, but SSD is way better to serve as the system disk than HDD. However, have you ever noticed that for better result, you need to align partitions on your SSD?

What if the partitions on SSD are not aligned?

If the partitions on SSD are not aligned, then the overall performance of SSD won’t be at its top level. However, this only matters a little when comparing with a more serious problem: the number of unnecessary writing operations will increase drastically which would shorten the lifespan of SSD eventually. Thus it’s very important to make sure that the partitions on our SSD are aligned.
