Most sites that allow uploads rely on SAN storage services like softlayer, which has multiple locations to  house the data.

there are many other soultions depend on the needs.

it begins with linuxboxes with a bunch of disks in array. usually with raid 4 5 or 6.
its the easiest and cheapest way to do it. just use lvm and create the file system from GUI.

you can install open filer which is an open source filer software similair to netapp .
it support nas san iscsi and so on. it has web and ssh management .

the next level is a dedicated filer like emc or netapp. you buy a package of software and hardware.
this solution is much more expensive then the first two but has some more stability , maybe performence ( depend on hardware ) and support.

the other are mid range to hi end storgae which cost a lot.

if i would do it i would use linux boxes with lvm arrays on each.
you got redundency , you can cluster them, you can expand file systems across machines, and its cheap.

Storage sites like that would probably use very large structured SANs with some kind of database to track users and their individual files as well as links and permissions to their files.

The easiest way is to deploy a server and connect it to a bunch of NAS. That's the way we deal in our company

They do use SAN but not only a simple SAN they also use SAN clusters in that they backup each other. There ae methods to do bolck level syncronization. Also they use multipoint mount of the volumes. So that all systems can mount the voulme simultaneously using multipath.
