    The Seagate Exos X18 18TB is bursting with GBytes of storage space. The hard drive offers a huge capacity of 18,000 GBytes, which want to be filled with large amounts of data. It is also extremely performant and shines in the test with very high transfer rates and low access times. The low price is also appealing - at least when measured against the storage space.
