Chapter 4 notes
Devices that store non volatile info and organize info into individual files: USB memory keys, recordable optical disks, solid state disks (SSD), battery backed RAM, and electromechanical hard disk drives. Common disk interface types : SAS, SATA, IDE, SCSI. These apply limits for how disk hardware connects to the computer. Disk storage: any device capable of storing files for a long period of time. Internal Disk: types (IDE,SATA,SCSI) non removable fixed disks attached to these internal interfaces and provide a suitable location to store operating system files required to start the computer. The firmware built in to the computer is designed to recognized supported internal disk storage and boot from at least one of the installed internal disks. External disks: External interfaces are used to connect removable portable disk storage. Typical external disk interface types include USB, eSATA, SCSI, and FireWire. Is useful for expanding a computers bulk file storage to contain application and user file data. but it is not suitable for operating system files that are essential and must always be present. Virtual Hard disk (VHD): publicly available from Microsoft, All file data stored in a VHD is actually stored in a single file on the file system of a real disk drive. A VHD may contain thousands of individual files from the user’s perspective, but it still only appears as one physical file on the real disk drive. Only windows 7 ultimate and enterprise can natively boot from a (VHD). Logical Drives: appears to windows 7 as one disk drive. Internal, external and VHD can all be logical drives. Multiple physical drives can be grouped together to appear as one drive. 2 reasons for doing this. Can have more combined space than one physical drive can have. And adds fault tolerance that allows for a physical drive to fail without losing access to the logical drive. Redundant array of inexpensive disks (RAID) software used to combine disks into logical
