2. Data recovery - Wikipedia

   en.wikipedia.org/wiki/Data_recovery

   The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.

3. Solid-state drive - Wikipedia

   en.wikipedia.org/wiki/Solid-state_drive

   A solid-state drive (SSD) is a type of solid-state storage device that uses integrated circuits to store data persistently. It is sometimes called semiconductor storage device, solid-state device, or solid-state disk. [1] [2] SSDs rely on non-volatile memory, typically NAND flash, to store data in memory cells. The performance and endurance of ...

4. External storage - Wikipedia

   en.wikipedia.org/wiki/External_storage

   Such storage devices may refer to removable media (e.g. punched paper, magnetic tape, floppy disk and optical disc), compact flash drives (USB flash drive and memory card), portable storage devices (external solid-state drive and enclosured hard disk drive), or network-attached storage.

5. Solid-state storage - Wikipedia

   en.wikipedia.org/wiki/Solid-state_storage

   The minimal chunk size (page) for a read operation is much smaller than the minimal chunk size (block) for a write/erase operation, resulting in an undesirable phenomenon called write amplification that limits the random write performance and write endurance of a flash-based storage device. Some solid-state storage devices use RAM and a battery ...

6. Removable media - Wikipedia

   en.wikipedia.org/wiki/Removable_media

   Examples of removable media that are standalone plug-and-play devices that carry their own reader hardwares include: USB flash drives [5] Portable storage devices. Dedicated external solid-state drives (SSD) Enclosured mass storage drives, i.e. modified hard disk drives (HDD)/internal SSDs; Peripheral devices that have integrated data storage ...

7. Direct-attached storage - Wikipedia

   en.wikipedia.org/wiki/Direct-attached_storage

   DAS consists of one or more storage units such as hard drives, solid-state drives, optical disc drives within an external enclosure. The term "DAS" is a retronym to contrast with storage area network (SAN) and network-attached storage (NAS).
