They phased out around 2015 to replace with the newer M.2 format which is way faster traditional 2.5" SATA SSD as it uses the PCI Express standard. A solid-state drive (SSD) is a type of solid-state storage device that uses integrated circuits to store data persistently.
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 ] Most disk partitioning schemes are designed to have files occupy an integral number of sectors regardless of the file's actual size.
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 first magnetic tape drive, the Univac Uniservo, recorded at the density of 128 bit/in on a half-inch magnetic tape, resulting in the areal density of 256 bit/in 2. [6] In 2015, IBM and Fujifilm claimed a new record for the magnetic tape areal density of 123 Gbit/in 2 , [ 7 ] while LTO-6 , the highest-density production tape shipping in 2015 ...
Many device interfaces or protocols (e.g., SATA, USB, SAS, PCIe) are used both inside many-device boxes, such as a PC, and one-device-boxes, such as a hard drive enclosure. Accordingly, this page lists both the internal ribbon and external communications cable standards together in one sortable table.
Historically, a byte was the number of bits used to encode a character of text in the computer, which depended on computer hardware architecture, but today it almost always means eight bits – that is, an octet. An 8-bit byte can represent 256 (2 8) distinct values, such as non-negative integers from 0 to 255, or signed integers from −128 to ...

In logical block addressing, only one number is used to address data, and each linear base address describes a single block. The LBA scheme replaces earlier schemes which exposed the physical details of the storage device to the software of the operating system. Chief among these was the cylinder-head-sector (CHS) scheme, where blocks were addressed by means
