What is Serial ATA (SATA)?

What does SATA stand for?

A serial superior generation attachment (serial ATA, SATA or S-ATA) is a Computer Bus Interface used to connect Host Bus Adapters with mass garage Devices like Optical Drives and tough drives. This interface is normally used to attach tough Disk Drives to a number sySTEM which includes a Laptop Motherboard. SATA is an replace to the parallel Signaling (parallel ATA or PATA) trendy of the 1980s used for more advantageous incorporated pressure electronics (EIDE) and the earlier included pressure electronics (IDE).

Serial ATA cHanged into added in 2005. In 2010, it become up to date to use a Records cable with seven conductors made of three Grounds and four energetic -pair facts strains with Wafer connectors at every stop.

What Does Serial Advanced Technology Attachment Mean?

SATA gives several benefits over ATA and PATA. The maximum advanced Functions are hot swapPing and quicker statistics Transfer Rates. Hot swapping is the potential to UPDATE pc gadget additives without having to shut down the device. Older systems needed to be close down earlier than replacing or installing machine Modules. SATA’s 6 Gbps facts Switch fee is also lots quicker than the ones of ATA and PATA.

The widespread interface for SATA is the superior Host Controller interface (AHCI), which includes revolutionary functions including hot swapping and Native Command Queuing. If the motherboard or Chipset does now not support AHCI, SATA will normally run in IDE Emulation Mode, which does no longer assist advanced features.

SATA additionally lets in native Command queuing (NCQ). This era is supposed to growth overall perFormance via letting the hard disc force augment the order in which Read/Write commands are applied. NCQ permits numerous instructions to be rescheduled and permits the host to ship more instructions to the difficult disk power at the same time as searching information for every other command. NCQ also permits the force to switch information the use of direct Memory get right of entry to operations without interference from the CPU.
