On Windows 9x and Windows NT, the ASPI manager is generic and relies on the services of SCSI miniport drivers. On those systems, the ASPI interface is designed for applications which require SCSI pass-through functionality (such as CD-ROM burning software). [1]: 57
USB Attached SCSI (UAS) or USB Attached SCSI Protocol (UASP) is a computer protocol used to move data to and from USB storage devices such as hard drives (HDDs), solid-state drives (SSDs), and thumb drives. UAS depends on the USB protocol, and uses the standard SCSI command set.
The storage port drivers provide an interface for Win32 applications to send SCSI Command Descriptor Block (CDB) messages to SCSI devices. The interfaces are IOCTL_SCSI_PASS_THROUGH and IOCTL_SCSI_PASS_THROUGH_DIRECT. Applications can build a pass-through request and send it to the device by using this IOCTL.
The SCST core, a protocol-independent engine for processing SCSI commands. Target drivers which receive SCSI commands from a SCSI initiator, pass these SCSI to the SCST core and send back replies to the initiator. Storage drivers a.k.a. device handlers which interact with the storage medium.
On a parallel SCSI bus, a device (e.g. host adapter, disk drive) is identified by a "SCSI ID", which is a number in the range 0–7 on a narrow bus and in the range 0–15 on a wide bus. On earlier models a physical jumper or switch controls the SCSI ID of the initiator ( host adapter ).
The Linux kernel has supported USB mass-storage devices since version 2.3.47 [3] (2001, backported to kernel 2.2.18 [4]).This support includes quirks and silicon/firmware bug workarounds as well as additional functionality for devices and controllers (vendor-enabled functions such as ATA command pass-through for ATA-USB bridges, used for S.M.A.R.T. or temperature monitoring, controlling the ...
SCSI Pass Through Direct (SPTD) is a proprietary device driver and application programming interface (API) that provides a method of access to SCSI storage devices. Originally developed in 2004 by Duplex Secure Ltd., it is now owned and maintained by Disc Soft Ltd., [ 1 ] the developer of Daemon Tools .
Windows 8 and later Windows operating systems support the unmap command for devices that use the SCSI driver stack, including USB Attached SCSI Protocol (UASP). Windows 8.1 and later Windows operating systems support the TRIM command for NVM Express SSDs. Microsoft has released an update for Windows 7 that adds NVM Express support including ...
