A 3.5-inch Serial ATA hard disk drive A 2.5-inch Serial ATA solid-state drive. SATA was announced in 2000 [4] [5] in order to provide several advantages over the earlier PATA interface such as reduced cable size and cost (seven conductors instead of 40 or 80), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through an (optional) I/O queuing ...
An mSATA SSD on top of a 2.5-inch SATA drive. Serial ATA (SATA). The SATA data cable has one data pair for differential transmission of data to the device, and one pair for differential receiving from the device, just like EIA-422. That requires that data be transmitted serially.
Optiarc is a brand of optical disc drives and solid-state drives. [1] It is owned by a US-based Vinpower Digital, Inc. Initially Optiarc was established on April 3, 2006 as a joint venture between Sony (55% shares) and NEC (45% shares).
Available in capacities between 30 GB (60 GB for SATA models) to 120 GB, with 2 MB cache (8 MB in SATA models), with either ATA/100 and SATA/150 interfaces. Barracuda V with SATA port is one of the first hard drives to feature a SATA interface. [23] The SATA models have many problems, including random data loss (such as disappearing partitions).
Although research into optical data storage has been ongoing for many decades, the first popular system was CD, introduced in 1982, adapted from audio to data storage (the CD-ROM format) with the 1985 Yellow Book, and re-adapted as the first mass market optical storage medium with CD-R and CD-RW in 1988.
The format was standardized as EIA-741 and co-published as SFF-8501 for disk drives, with other SFF-85xx series standards covering related 5.25 inch devices (optical drives, etc.) [33] The Quantum Bigfoot HDD was the last to use it in the late 1990s, with "low-profile" (≈25 mm) and "ultra-low-profile" (≈20 mm) high versions.
Optical drives for computers come in two main form factors: half-height (also known as desktop drive) and slim type (used in laptop computers and compact desktop computers). They exist as both internal and external variants. Half-height optical drives are around 4 centimetres tall, while slim type optical drives are around 1 cm tall.
Disk storage (also sometimes called drive storage) is a data storage mechanism based on a rotating disk. The recording employs various electronic, magnetic, optical, or mechanical changes to the disk's surface layer. A disk drive is a device implementing such a storage mechanism.
