SSDs move data that’s already on your disk to other places on your disk, often sticking it at a temporary position first.

Is index fragmentation bad?

Index fragmentation is bad on traditional, spinning disk drives because the read head has to dance all around to gather the scattered data, slowing everything down. With solid state drives there are no moving parts and thus access is much, much faster.

Does database index require additional storage?
