Recently, the traditional Perpendicular Magnetic Recording (PMR) Hard Disk Drives (HDDs) have reached their bottleneck in providing higher areal density by continuously shrinking the grain volume, because of the superparamagnetic effect (SPE). To break the maximal areal density (i.e., 1 TB per square inch) of PMR technology, various new magnetic recording storage technologies have been investigated and proposed. Among these emerging technologies, Shingled Magnetic Recording (SMR) is the most promising one for being widely commercialized. Although SMR technology enables lower-cost and higher-density HDDs, SMR technology may suffer from poor runtime performance and poor responsiveness problems. This talk will first talk about the advance of HDDs and how the emerging SMR technology can lead HDDs for another success of decades. Then, this talk will demonstrate the potentials of taking advantage of resources or knowledge from the host system, so as to improve the runtime performance or responsiveness for SMR disks.
