  2. Advanced Host Controller Interface - Wikipedia

    en.wikipedia.org/wiki/Advanced_Host_Controller...

    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.

  3. Native Command Queuing - Wikipedia

    en.wikipedia.org/wiki/Native_Command_Queuing

    [4] [5] Linux kernels support AHCI natively since version 2.6.19, and FreeBSD fully supports AHCI since version 8.0. Windows Vista and Windows 7 also natively support AHCI, but their AHCI support (via the msahci service) must be manually enabled via registry editing if controller support was not present during their initial install.

  4. Aggressive Link Power Management - Wikipedia

    en.wikipedia.org/wiki/Aggressive_Link_Power...

    When enabled via the AHCI controller, this allows the SATA host bus adapter to enter a low-power state during periods of inactivity, thus saving energy. The drawback to this is increased periodic latency as the drive must be re-activated and brought back on-line before it can be used, and this will often appear as a delay to the end-user.

    en.wikipedia.org/wiki/Intel_Rapid_Storage_Technology

    Intel Rapid Storage Technology (RST) is a driver SATA AHCI and a firmware-based RAID solution built into a wide range of Intel chipsets. Currently also is installed as a driver for Intel Optane temporary storage units. It contains two operation modes that follow two Intel specific modes rather than the SATA standard. The name modes and the ...

  6. Trim (computing) - Wikipedia

    en.wikipedia.org/wiki/Trim_(computing)

    The ATA standard is supported by both parallel (IDE, PATA) and serial (SATA) ATA hardware. A drawback of the original ATA TRIM command is that it was defined as a non-queueable command and therefore could not easily be mixed with a normal workload of queued read and write operations. SATA 3.1 introduced a queued TRIM command to remedy this. [69]

    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 ...

  9. Tagged Command Queuing - Wikipedia

    en.wikipedia.org/wiki/Tagged_Command_Queuing

    Tagged Command Queuing (TCQ) is a technology built into certain ATA and SCSI [1] hard drives. It allows the operating system to send multiple read and write requests to a hard drive. ATA TCQ is not identical in function to the more efficient Native Command Queuing (NCQ) used by SATA drives. [2] SCSI TCQ does not suffer from the same limitations ...
