Paper Title: Managed NAND Storage Endurance Challenges in Enterprise Class Mobile Computers

Paper Abstract: There are major storage endurance challenges for computing systems expected to have long life-cycles (6 to 10 years) and are subjected to heavy small random write workloads. The presentation will explain the challenges of measuring, monitoring, comparing and improving the endurance of Managed NAND storage devices, highlighting the importance of the file system used. The presentation will show a way to Measure the endurance of Managed NAND using the info from the governing JEDEC Standard and will also suggest ways to improve, in the future, the JEDEC Standard to help the monitoring of the storage life-cycle. Using the measurement method introduced, the presentation will show the significant performance and endurance gain by switching the file system from ext4 to the Flash Friendly File System F2FS. A further benefit of the presentation will be the ability to predict the expected life of the storage under the current workload.
