Storage Concepts File Systems Formatting Disks Network Protocols for Data Types of Disks File Systems

Controls how data is stored, retrieved, and configured. Contains index of files. Extended (ExFAT)

Designed by Microsoft back in 2006 as a lightweight to be used in Windows CE.

Fast and Light Optimized for Flash Very Compatible 16 Exbibytes SSD Android, Game consoles, Very Fast Used with Embedded iOS 7+, older Windows Systems New Technology File System (NTFS)

The primary file system for recent versions of Windows and Windows Server. Contains metadata about the drive with advanced features

Reliable Secure Flexible Checkpoints, Access Control List Up to 256TB Consistency checks Bitlocker Long names (not 8.3) Self-healing Large Volumes Quotas, compression ReFS

Microsoft's newest file system, designed to maximize data availability, scale efficiently to large data sets across diverse workloads, and provide data integrity by means of resiliency to corruption

Resilient High Performance Scalable Integrity-streams Tier Optimization Very Large Data Sets Storage Spaces VM optimized Up to 35PB Error correction Sparse VDL Variable cluster sizes Other File Systems

File Allocation Table (FAT, FAT32) - 8.3, very limited exFAT - Used for flash drives Universal Disk Format (UDF) - Used for DVD and CD-Roms Network Data Protocols

Used for sharing and distributing data across networks Server Message Blocks (SMB) Network file sharing protocol that allows applications on a computer to read and write to files and to request services from server programs in a computer network. (NFS) Transfer files between computers running Windows and other non-Windows operating systems, such as Linux or UNIX. Internet Small Computer Systems Interface (iSCSI) Internet Protocol (IP)-based storage networking for linking data storage facilities. It connects devices to networked Storage. Storage QoS Provides a way to centrally monitor and manage storage performance for virtual machines using Hyper-V and the Scale-Out File Server roles Using Data Deduplication

Reduce impact of redundant data Finds duplicated data Add feature to server Enable Dedup on volume
