Also, flash-based devices experience memory wear that reduces service life resulting from limitations of flash memory that impose a finite number of program–erase cycles used to write data. Due to this, solid-state storage is frequently used for hybrid drives , in which solid-state storage serves as a cache for frequently accessed data ...
Flash memory does not have the mechanical limitations and latencies of hard drives, so a solid-state drive (SSD) is attractive when considering speed, noise, power consumption, and reliability. Flash drives are gaining traction as mobile device secondary storage devices; they are also used as substitutes for hard drives in high-performance ...
That said, the price of high-capacity drives has fallen rapidly, and this is indeed an effect of density. The highest capacity drives use more platters, essentially individual hard drives within the case. As the density increases, the number of platters can be reduced, leading to lower costs. Hard drives are often measured in terms of cost per bit.
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 ...
For consecutive sector writes and reads (for example, from an unfragmented file), most hard drives can provide a much higher sustained data rate than current NAND flash memory, though mechanical latencies seriously impact hard drive performance. Unlike solid-state memory, hard drives are susceptible to damage by shock (e.g., a short fall) and ...
The turn of the millennium saw the widespread introduction of solid-state removable media, with the SD card being introduced in 1999, followed by the USB flash drive in 2000. [21] The capacity of these removable flash drives improved over time, with 2013 seeing Kingston unveiling a 1 terabyte USB flash drive. [22]

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.
