Why does digital storage always have the same values eg. 32gb, 64gb, 128gb, 256gb etc. and why do they double every time they go up in size? Is this a limitation or just a standard?

Read the other answers about powers of two. But with flash technology today there’s no need to stay with those standard sizes apart from tradition. The storage has to have spare capacity to deal with defects and failures so a 1GiB drive has slightly more storage than that internally. With SSDs you can get sizes like 200GB, 240GB and 256GB. Spinning disks have had sizes like this for even longer. Even the early floppy disks were multiples of 360 or 400kiB.
So, tradition, and having a common set of sizes for all manufacturers makes it easy for consumers to compare value.
