You'll have 7x2TB of storage to use. The parity bits are a check that makes sure that the data for that stripe on the drives is correct. If a hard drive fails, that data can be recovered because the parity bit will allow reconstruction of the corrupted data. Instead of having all the backup on one drive, it's spread across all of them.
