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 ...
Serial ATA International Organization (SATA-IO) is an independent, non-profit organization which provides the computing industry with guidance and support for implementing the SATA specification. SATA-IO was developed by and for leading industry companies.

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).
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 2.5-inch drive format is standardized in the EIA/ECA-720 co-published as SFF-8201; when used with specific connectors, more detailed specifications are SFF-8212 for the 50-pin (ATA laptop) connector, SFF-8223 with the SATA, or SAS connector and SFF-8222 with the SCA-2 connector.
The CX series supports both SATA and Fibre Channel disks. Supported RAID levels are 1/0, 0, 1, 3, 5, and 6; the disks can be configured into groups with different RAID levels. Models of the CX series come in two configurations: Fibre Channel (transfer speeds max. 2 Gbit/s) and iSCSI (max. 1 Gbit/s). The exception is the CX700, which is FC only.
AHCI is separate from the SATA 3 Gbit/s standard, although it exposes SATA's advanced capabilities (such as hot swapping and native command queuing) such that host systems can utilize them. For modern solid state drives, the interface has been superseded by NVMe. [2] The current version of the specification is 1.3.1.
