I NFORMATION is being generated at a rapid pace. To sustain this information revolution, next-generation data storage must be more practical, economical, and reliable than ever before. There are presently more than half a million data centers world-wide and this number is expected to rise even further. Companies like Google, Facebook, and Microsoft have already invested billions of dollars into their data center infrastructure. To make such storage systems economically viable, new solutions

A key enabling technology at both device-and network-level of reliable storage is fundamentally rooted in mathematical models, algorithms, and techniques for data communication. The goal of this special issue is to offer a publication venue to advance the state of the art in communication methods for emerging storage systems. At the device physics level, a wide range of new technologies are being actively investigated. Solid state drives (NAND flash based and DRAM based) are rapidly gaining importance due to their energy efficiency at high access speeds. Such non-volatile memories (NVMs) have already found use in consumer electronics and in enterprise storage, but still lag hard disk drives in terms of the cost. While very promising, these technologies present new challenges in lifetime and reliability, which will require non-conventional solutions. At the system level, massive distributed storage networks, data centers, and cloud storage systems desperately need new methods to improve storage efficiency and data transfer speeds. Computer architectures, file systems, data classification and search, security, and interaction with data networks L. Dolecek is with the
