Bridge chips were widely used on PATA drives (before the completion of native SATA drives) as well in standalone converters. When attached to a PATA drive, a device-side converter allows the PATA drive to function as a SATA drive. Host-side converters allow a motherboard PATA port to connect to a SATA drive.
The connector on the host side accepts either one PCI Express SSD or up to two legacy SATA devices, by providing either PCI Express lanes or SATA 3.0 ports depending on the type of connected storage device. [13] There are five types of SATA Express connectors, differing by their position and purpose: [2]
The SAS is a new generation serial communication protocol for devices designed to allow for much higher speed data transfers and is compatible with SATA. SAS uses a mechanically identical data and power connector to standard 3.5-inch SATA1/SATA2 HDDs, and many server-oriented SAS RAID controllers are also capable of addressing SATA hard drives.
The CPU is located at the top of the map at due north. The CPU is connected to the chipset via a fast bridge (the northbridge) located north of other system devices as drawn. The northbridge is connected to the rest of the chipset via a slow bridge (the southbridge) located south of other system devices as drawn.
SATA is a computer bus interface for connecting host bus adapters to mass storage devices such as hard disk drives and optical drives. eSATA is a SATA connector accessible from outside the computer, to provide a signal (but not power) connection for external storage devices.
In 2003, and in conjunction with the i865 and i875 northbridges, the ICH5 was created. A SATA host controller was integrated. The ICH5R variant additionally supported RAID 0 on SATA ports. Eight USB-2.0 ports were available. The chip had full support for ACPI 2.0. It had 460 pins. Since 1999 the 266 MB/s hub interface was assumed to be a ...
The Advanced Host Controller Interface (AHCI) is a technical standard defined by Intel that specifies the register-level interface of Serial ATA (SATA) host controllers in a non-implementation-specific manner in its motherboard chipsets.
The terms are primarily used to refer to devices for connecting SCSI, SAS, NVMe, Fibre Channel and SATA devices. [2] Devices for connecting to FireWire, USB and other devices may also be called host controllers or host adapters. Host adapters can be integrated in the motherboard or be on a separate expansion card. [3]
