This is the Model 305 Disk Storage unit, later called the Random Access Method of Accounting and Control made by IBM in 1956. One of the first Disk Drives which initially came to the forefront in 1955.

It's the first computer that had a hard disk made by IBM
Congratulations!
Now think of what is happening today.
Probably you are already carrying a USB key in your pocket with storage of about 64GB (more than 1000 times what IBM 305 had). The new database technologies like SAP HANA can now handle more than 50 Terrabyte size of data. But the real huge data is handled by MapReduce framework for data which is measured in Petabytes. For instance Google's "Big Table". If you interested in learning more about these huge databases, then learn Open Source Hadoop and HBase implementations. It is a very exciting technology of future.

Thank you sir for this information. We shall surely give it a look after our mid-semester exams.
