Storage is one of those things you probably don't think about much until you're running low. But compared to phones such as the iPhone XS and Pixel 3, Samsung's S10 starting options are generous. 

The S10E starts at 128GB, and has a microSD card slot to give you potentially up to 512GB more. For people with truckloads of files to store, the S10 Plus can get you all the way to 1TB of storage space (with 12GB of RAM), or 1.5TB with that added microSD card. Is Samsung just showing off? Maybe. But do you really mind?
