A SATA 2.0 (3 Gbit/s) PCI Express ×1 expansion card, having two built-in SATA port multipliers (square chips to the left and right of the middle of PCB) that "splice" card chipset's two SATA ports into a total of eight ports. A Serial ATA port multiplier (SATA PM) is a device that allows multiple SATA devices to be connected to a single SATA ...
eSATAp throughput is not necessarily the same as SATA, many enclosures and docks that support both eSATA and USB use combo bridge chips which can severely reduce the throughput, and USB throughput is that of the USB version supported by the port (typically USB 3.0 or 2.0). eSATAp ports (bracket versions [clarification needed]) can run at a ...
Mechanically, connectors on the host side retain their backward compatibility in a way similar to how USB 3.0 does it – the new host-side SATA Express connector is made by "stacking" an additional connector on top of two legacy standard SATA data connectors, which are regular SATA 3.0 (6 Gbit/s) ports that can accept legacy SATA devices.
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 ...
Per specification, SATA 2.0 makes use of port multipliers to achieve port expansion, and some port multiplier manufacturers have implemented multipath I/O using port multiplier hardware. SATA is marketed as a general-purpose successor to parallel ATA and has become common in the consumer market, whereas the more-expensive [when?
2 SATA ports supporting 6/3/1.5 gigabaud operation; 4 SATA ports supporting 3/1.5 gigabaud operation; one PCI 2.3 32-bit 33 MHz bus interface; 14 USB 2.0 ports; single-port Gigabit Ethernet controller; Active Management Technology 7.0 and Anti-Theft Technology; HD Audio controller; Some chipset variants have additional mass storage interfaces:
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 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.
