SSD Fundamentals - Amit Berman

Abstract

Modern NAND Flash-based Solid-State Drives (SSD) presents low latency, high throughput, low power consumption and solid-state reliability improvements comparing to traditional magnetic-disk based Hard Disk Drives (HDD). In this talk, I will review solid-state drive technology, including introduction to flash memory structure and operating principles, storage of multiple bits per cell, endurance and retention characteristics, approaches for high performance as well as power conserving write/read/erase policies, wear leveling, write amplification, file systems for solid-state non-volatile memory, concepts of interconnections and I/O communication protocols.
