    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.

    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 ...

    When a SATA controller is configured to operate in IDE Mode, the number of storage devices per controller is usually limited to four (two IDE channels, master device and slave device with up to two devices per channel), compared to the maximum of 32 devices/ports when configured in AHCI mode.

  5. Native Command Queuing - Wikipedia

    [1] [2] Because the ATA TCQ is rarely used, Parallel ATA (and the IDE mode of some chipsets) usually only support one outstanding command per port. For NCQ to be enabled, it must be supported and enabled in the SATA host bus adapter and in the hard drive itself.

  6. Parallel ATA - Wikipedia

    en.wikipedia.org/wiki/Parallel_ATA

    Parallel ATA (PATA), originally AT Attachment, also known as Integrated Drive Electronics (IDE), is a standard interface designed for IBM PC-compatible computers. It was first developed by Western Digital and Compaq in 1986 for compatible hard drives and CD or DVD drives.

  7. SATA Express - Wikipedia

    The Serial ATA interface was designed primarily for interfacing with hard disk drives (HDDs), doubling its native speed with each major revision: maximum SATA transfer speeds went from 1.5 Gbit/s in SATA 1.0 (standardized in 2003), through 3 Gbit/s in SATA 2.0 (standardized in 2004), to 6 Gbit/s as provided by SATA 3.0 (standardized in 2009).

    Each generation of floppy disk drive (FDD) began with a variety of incompatible interfaces but soon evolved into one de facto standard interface for the generations of 8-inch FDDs, 5.25-inch FDDs and 3.5-inch FDDs. [1]

    The raid mode only supports IDE Hard Disk Drives and includes RAID 0, RAID 1, Raid 0+1 and JBOD, along with a "normal" mode that essentially acts as a standard Hard Disk controller. Optical disk drives such as CD-ROM and DVD drives are supported by the ATAPI mode, which also supports Hard Disk Drives at the loss of all RAID functions.
