| Term | Definition |
|---|---|
| BCD (Boot Configuration Data) | a small database that holds parameters Windows needs for a successful boot |
| bootrec | command to rebuild the BCD (Boot Configuration Data) |
| CD (compact disc) | laser optical storage technologies |
| CDFS (Compact Disc File System) | the file system is used by CDs |
| CFexpress card | Flash memory cards that offer faster data transfer because they are designed using the PCIe 3.0 interface standard |
| chkdsk | a command to search for bad sectors on drive C: and recover data |
| CompactFlash (CF) card | Flash memory cards with relatively lower capacity that come in two types - Type I and Type II |
| Defrag and Optimization tool (dfrgui.exe) | a utility to optimize drives by defragmenting a magnetic drive or trimming an SSD |
| disk cloning | recreating the system configuration onto the new hard drive |
| diskpart | command line tool used to manage disks and partitions |
| fault tolerance | a computer’s ability to respond to a fault or catastrophe so data is not lost |
| file system | the overall structure the operating system uses to name, store, and organize files on a drive |
| formatting | using Windows to install a new file system on a device or logical drive in a process that erases all data on the device or drive |
| hot-swapping | you can connect and disconnect a drive while the system is running |
| IDE (Integrated Drive Electronics) | connection to a motherboard using Parallel ATA (PATA) standards |
| IOPS (input/output operations per second) | measurement of the amount of read or write operations performed in one second |
| latency | measurement of the time required to process a data request or transaction |
| low-level formatting | the process of writing sector markings on a magnetic drive before it leaves the factory |
| magnetic hard drive | a permanent storage device in a computer that has multiple platters, or disks, that stack together and spin in unison inside a sealed metal housing |
| mirrored volume | the name Windows gives RAID 1 |
| NAND flash memory | the memory used in a solid-state drive |
| NVMe (Non-Volatile Memory Express or NVM Express | an interface standard used only by solid-state drive |
| RAID (redundant array of inexpensive disks or redundant array of independent disks) | technology that configures two or more hard drives to work together as an array of drives |
| RAID 0 | a type of mirroring that uses two or more physical disks to increase the disk space available for a single volume |
| RAID 1 | a type of mirroring that duplicates data on one drive to another drive and is used for fault tolerance |
| RAID 5 | a type of mirroring that stripes data and parity information across three or more drives and uses parity checking, so if one drive fails, the other drives can recreate the data stored on the failed drive by using the parity information |
| RAID 10 or RAID 1+0 | the combination of RAID 1 and RAID 0, made up of at least four disks with data being mirrored across pairs of disks |
| read/write head | a hard disk component that reads data from and writes data to the disk |
| SATA Express | technology that uses a new SATA connector that allows for PCIe and SATA to work together |
| SCSI (Small Computer System Interface) | a set of standards for physically connecting and transferring data between computers and peripheral devices |
| SD (Secure Digital) card | memory cards which follow the standards of the SD Association |
| Spanning | the method of using two hard drives to hold a single Windows volume, and when it is full, the data continues to be written to the second |
| SSD (solid-state drive or solid-state device) | a memory drive with no moving parts flash memory is stored on chips on a circuit board inside the drive housing |
| striped volume | the name Windows gives RAID 0 |
| throughput | the amount of data that flows through a point in the data path over one second’s time |
| UDF (Universal Disk Format) | the file system is used by CDs, as well as DVDs and BDs (Blu-ray discs) in newer versions. |
| Volume | a new logical drive in the system, it determines which file system the drive is using, assigns it a drive letter |
| wear leveling | a technique which assures that the logical block addressing does not always address the same physical blocks in order to distribute write operations more evenly across the device |
| XQD card | Flash memory cards using the PCIe 2.0 standard as the interface |
