Blog 33: High-Capacity Data Storage Systems One of the most important technological requirements of big data is having enough storage capacity to handle extremely large amounts of information. Traditional storage systems are often unable to manage the massive volume of data generated every second from social media platforms, online shopping websites, healthcare systems, and smart devices. As a result, organisations require advanced storage technologies that can store structured, semi-structured, and unstructured data efficiently.

Companies such as Amazon Web Services , Google Cloud , and Microsoft Azure provide scalable storage services that allow businesses to expand their storage space whenever needed. This flexibility reduces costs because companies only pay for the storage they use. Distributed storage systems are also essential. Technologies such as Hadoop Distributed File System (HDFS) divide large...
