It all depends on how you plan to use your laptop. For example, if you’re a photographer who needs to store large files, you will need significantly more storage space than someone who just browses the internet and checks their email. A good rule of thumb is that a minimum of 16GB will be enough for personal use with an operating system and some basic programs. If you decide to purchase a laptop with less than 16 GB of storage, make sure it has an SD card slot as that can provide extra space.
