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 ...
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.
Staggered spin-up (SSU) was introduced into SATA revision 2.5 in 2005. [2] SSU allows a SATA host bus adapter to spin up hard drives in a sequential manner. [ 3 ] In SATA 2.5 and above, the drive starts without spinup if the "disabled stagged spinup" (DSS) pin (standard power connector pin 11) is left floating.
A disk-on-a-module (DOM) is a flash drive with either 40/44-pin Parallel ATA (PATA) or SATA interface, intended to be plugged directly into the motherboard and used as a computer hard disk drive (HDD). DOM devices emulate a traditional hard disk drive, resulting in no need for special drivers or other specific operating system support.
U.3 (SFF-TA-1001) is built on the U.2 spec and uses the same SFF-8639 connector. A single "tri-mode" (PCIe/SATA/SAS) backplane receptacle can handle all three types of connections; the controller automatically detects the type of connection used. This is unlike U.2, where users need to use separate controllers for SATA/SAS and NVMe.
SATA Express (sometimes unofficially shortened to SATAe) is a computer bus interface that supports both Serial ATA (SATA) and PCI Express (PCIe) storage devices, initially standardized in the SATA 3.2 specification. [1]
A Serial ATA port multiplier (SATA PM) is a device that allows multiple SATA devices to be connected to a single SATA host port. Many common controllers do not support this feature, [ 1 ] as it is not a requirement for a SATA controller.
In 1993, Seagate released the first Barracuda drive, with the ST11950. The drive had a capacity of 2.03 GB (1.69 GB formatted), was available with FAST SCSI-2 (N/ND models) or WIDE SCSI-2 (W/WD models) interface, and was the first hard drive ever to have a spindle speed of 7200-RPM.
