In our everyday lives, we create massive amounts of data. But how much does it really cost to store data? With ever decreasing cost of storage media, a popular misconception is that the cost of storage has become cheaper than ever. However, we argue that the cost of storing data is not equal to the cost of storage media alone – rather, many often ignored factors including human, infrastructure,...

Current digital data storage systems are able to store huge amounts of data. Even though the data density of digital information storage has increased tremendously over the last few decades, the data longevity is limited to only a few decades. If we want to preserve anything about the human race which can outlast the human race itself, we require a data storage medium designed to last for 1 mil...

Efficient data storage is a key component of data managing systems to achieve good performance. However, currently data storage is either heavily constrained by static decisions (e.g. fixed data stores in DBMSs) or left to be tuned and configured by users (e.g. manual data backup in File Systems). In this paper, we take a holistic view of data storage and envision a virtual storage layer. Our v...

With the advent of the big data era, cloud data storage and retrieval have become popular for efficient data management in large companies and organizations, thus they can enjoy the on-demand high-quality cloud storage service. Meanwhile, for security reasons, those companies and organizations would like to verify the integrity of their data once storing it in the cloud. To address this issue, ...

In this paper, we demonstrate the concept of a distributed file system that supports file versioning, file sharing, and endless files based on sliding window approach. It uses a distributed storage substrate that provides immutable block allocations, and a metadata manager, that maps files to data blocks using metadata. While file versioning and read-write sharing are often understood as contra...

Wireless sensor networks provide an effective tool for acquiring sensor measurements across a large area. Devices in a sensor field can automatically configure themselves into a working network, ready to collect data. The challenge is to collect that data in a timely and power-efficient manner. In some environments, a data collection device (sink) may need to travel periodically through the fie...

Nowadays, data storage requirements from end-users are growing, demanding more capacity, more reliability and the capability to access information from anywhere. Cloud storage services meet this demand by providing transparent and reliable storage solutions. Most of these solutions are built on distributed infrastructures that rely on data redundancy to guarantee a 100% of data availability. Un...

Operating points to achieve Terabyte tape cartridge capacities and beyond drive both linear and track densities to values not perceived possible a few short years ago. The primary contributors to the issues related to these high capacities are the physical and magnetic properties of the tape media itself. The total magnetic moment of the recorded bit, driven by the magnetic coating thickness, d...
