    [1] [2] [3] Although UAS was added in the USB 3.0 standard, it can also be used at USB 2.0 speeds, assuming compatible hardware. [4] When used with an SSD, UAS is considerably faster than BOT for random reads and writes given the same USB transfer rate. The speed of a native SATA 3 interface is 6.0 Gbit/s. When using a USB 3.0 link (5.0 Gbit/s ...

  3. USB 3.0 - Wikipedia

    en.wikipedia.org/wiki/USB_3.0

    USB 3.0 port provided by an ExpressCard-to-USB 3.0 adapter may be connected to a separately-powered USB 3.0 hub, with external devices connected to that USB 3.0 hub. On the motherboards of desktop PCs which have PCI Express (PCIe) slots (or the older PCI standard), USB 3.0 support can be added as a PCI Express expansion card .

  4. Extensible Host Controller Interface - Wikipedia

    en.wikipedia.org/wiki/Extensible_Host_Controller...

    The eXtensible Host Controller Interface (xHCI) is a technical specification that provides a detailed framework for the functioning of a computer's host controller for Universal Serial Bus (USB). Known alternately as the USB 3.0 host controller specification, xHCI is designed to be backward compatible, supporting a wide range of USB devices ...

  5. USB mass storage device class - Wikipedia

    en.wikipedia.org/wiki/USB_mass_storage_device_class

    The USB mass storage device class (also known as USB MSC or UMS) is a set of computing communications protocols, specifically a USB Device Class, defined by the USB Implementers Forum that makes a USB device accessible to a host computing device and enables file transfers between the host and the USB device. To a host, the USB device acts as an ...

    The written USB 3.0 specification was released by Intel and its partners in August 2008. The first USB 3.0 controller chips were sampled by NEC in May 2009, [4] and the first products using the USB 3.0 specification arrived in January 2010. [5] USB 3.0 connectors are generally backward compatible, but include new wiring and full-duplex operation.

  7. USB - Wikipedia

    en.wikipedia.org/wiki/USB

    Despite USB 3.0 being 10 times faster than USB 2.0, USB 3.0 transfer cables are only 2 to 3 times faster given their design. [clarification needed] The USB 3.0 specification introduced an A-to-A cross-over cable without power for connecting two PCs. These are not meant for data transfer but are aimed at diagnostic uses.

  8. eSATAp - Wikipedia

    en.wikipedia.org/wiki/ESATAp

    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 ...

  9. Host controller interface (USB, Firewire) - Wikipedia

    en.wikipedia.org/wiki/Host_controller_interface...

    Open Host Controller Interface (OHCI) [1] is an open standard.. Die shot of a VIA VT6307 Integrated Host Controller used for IEEE 1394A communication. When applied to an IEEE 1394 (also known as FireWire; i.LINK or Lynx) card, OHCI means that the card supports a standard interface to the PC and can be used by the OHCI IEEE 1394 drivers that come with all modern operating systems.
