2. Solid-state storage - Wikipedia

   en.wikipedia.org/wiki/Solid-state_storage

   A solid-state drive (SSD) provides secondary storage for relatively complex systems including personal computers, embedded systems, portable devices, large servers and network-attached storage (NAS). To satisfy such a wide range of uses, SSDs are produced with various features, capacities, interfaces and physical sizes and layouts.

3. External storage - Wikipedia

   en.wikipedia.org/wiki/External_storage

   Today storage devices may be internal or external to a computer system. In the 1950s, introduction of magnetic tapes and hard disk drives allowed for mass external storage of information, which played the key part of the computer revolution. [6] Initially all external storage, tape and hard disk drives are today available as both internal and ...

4. Solid-state drive - Wikipedia

   Comparison of NAND-based SSD and HDD Attribute or characteristic Solid-state drive (SSD) Hard disk drive (HDD) Price per capacity SSDs are generally more expensive than HDDs and are expected to remain so. As of early 2018, SSD prices were around $0.30 per gigabyte for 4 TB models. [23]

5. Density (computer storage) - Wikipedia

   en.wikipedia.org/wiki/Density_(computer_storage)

   Hard disk drives store data in the magnetic polarization of small patches of the surface coating on a disk. The maximum areal density is defined by the size of the magnetic particles in the surface, as well as the size of the "head" used to read and write the data. In 1956 the first hard drive, the IBM 350, had an areal density of 2,000 bit/in 2.

6. Disk sector - Wikipedia

   en.wikipedia.org/wiki/Disk_sector

   For most disks, each sector stores a fixed amount of user-accessible data, traditionally 512 bytes for hard disk drives (HDDs), and 2048 bytes for CD-ROMs, DVD-ROMs and BD-ROMs. [1] Newer HDDs and SSDs use 4096 byte (4 KiB) sectors, which are known as the Advanced Format (AF). The sector is the minimum storage unit of a hard drive. [2]

7. List of disk drive form factors - Wikipedia

   8-, 5.25-, 3.5-, 2.5-, 1.8- and 1-inch HDDs, together with a ruler to show the length of platters and read-write heads A newer 2.5-inch (63.5 mm) 6,495 MB HDD compared to an older 5.25-inch full-height 110 MB HDD. IBM's first hard drive, the IBM 350, used a stack of fifty 24-inch platters and was of a size comparable to two large refrigerators.

8. Enterprise and Data Center Standard Form Factor - Wikipedia

   en.wikipedia.org/wiki/Enterprise_and_Data_Center...

   EDSFF SSDs come in four form factors: E1.L (Long) and E1.S (Short), which fit vertically in a 1u server, and E3.L and E3.S, which fit vertically in a 2u server. [2] E3.S is approximately the size of an 2.5 inch (U.2) drive. [3] Samsung's NGSFF (also known as M.3 or NF1) form factor competes with EDSFF. [4]

9. List of Intel SSDs - Wikipedia

   The first, the SSD 510, used an SATA 6 Gigabit per second interface to reach speeds of up to 500 MB/s. [14] The drive, which uses a controller from Marvell Technology Group, [15] was released using 34 nm NAND Flash and came in capacities of 120 GB and 250 GB. The second product announcement, the SSD 320, is the successor to Intel's earlier X25-M.
