Starting with Windows 10, Version 2004 (OS build 19041.488 or higher), two additional identifiers are available for NVMe storage disk drives which support the STOR_RICH_DEVICE_DESCRIPTION structure:
SCSIt*v(8)p(40)

In versions of Windows prior to Windows 10, Version 2004 (OS build 19041.488 or higher), the device ID format for a small computer system interface (SCSI) device is as follows:
SCSIt*v(8)p(16)r(4)
Where:
t* is a device type code of variable length
v(8) is an 8-character vendor identifier
p(16) is a 16-character product identifier
r(4) is a 4-character revision level value
The bus enumerator determines the device type by indexing an internal string table, using a numerically encoded SCSI device type code, obtained by querying the device, as shown in the following table. The remaining components are just strings returned by the device, but with special characters (including space, comma, and any nonprinting graphic) replaced with an underscore.
The SCSI Port driver currently returns the following device type strings, the first nine of which correspond to standard SCSI type codes.
| SCSI type code | Device type | Generic type | Peripheral ID |
|---|---|---|---|
| DIRECT_ACCESS_DEVICE (0) | Disk | GenDisk | DiskPeripheral |
| SEQUENTIAL_ACCESS_DEVICE (1) | Sequential | TapePeripheral | |
| PRINTER_DEVICE (2) | Printer | GenPrinter | PrinterPeripheral |
| PROCESSOR_DEVICE (3) | Processor | OtherPeripheral | |
| WRITE_ONCE_READ_MULTIPLE_DEVICE (4) | Worm | GenWorm | WormPeripheral |
| READ_ONLY_DIRECT_ACCESS_DEVICE (5) | CdRom | GenCdRom | CdRomPeripheral |
| SCANNER_DEVICE (6) | Scanner | GenScanner | ScannerPeripheral |
| OPTICAL_DEVICE (7) | Optical | GenOptical | OpticalDiskPeripheral |
| MEDIUM_CHANGER (8) | Changer | ScsiChanger | MediumChangerPeripheral |
| COMMUNICATION_DEVICE (9) | Net | ScsiNet | CommunicationsPeripheral |
| 10 | ASCIT8 | ScsiASCIT8 | ASCPrePressGraphicsPeripheral |
| 11 | ASCIT8 | ScsiASCIT8 | ASCPrePressGraphicsPeripheral |
| 12 | Array | ScsiArray | ArrayPeripheral |
| 13 | Enclosure | ScsiEnclosure | EnclosurePeripheral |
| 14 | RBC | ScsiRBC | RBCPeripheral |
| 15 | CardReader | ScsiCardReader | CardReaderPeripheral |
| 16 | Bridge | ScsiBridge | BridgePeripheral |
| 17 | Other | ScsiOther | OtherPeripheral |
An example of a device ID for a disk drive would be as follows:
SCSIDiskSEAGATE_ST39102LW_______0004
There are four hardware IDs in addition to the device ID:
SCSIt*v(8)p(16)
SCSIt*v(8)
SCSIv(8)p(16)r(1)
V(8)p(16)r(1)
In the third and fourth of these additional identifiers, r(1) represents just the first character of the revision identifier. These hardware IDs are illustrated by the following examples:
SCSIDiskSEAGATE_ST39102LW_______
SCSIDiskSEAGATE_
SCSIDiskSEAGATE_ST39102LW_______0
SEAGATE_ST39102LW_______0
The SCSI Port driver supplies only one compatible ID, one of the variable-sized generic type codes from the previous table.
For example, the compatible ID for a disk drive is as follows:
GenDisk
The generic identifier is used in INF files for SCSI devices more than any other, because SCSI drivers are typically generic.
Be aware that the SCSI Port driver returns no generic name for sequential access and 'processor' devices.
-->In addition to the SCSI Port driver, Microsoft Windows Server 2003 and later versions provide Storport (storport.sys), a storage port driver that is especially suitable for use with high-performance buses, such as fibre channel buses, and RAID adapters.
There are several advantages to using Storport rather than the SCSI Port driver:
Improved performance, both in terms of throughput and the system resources that are utilized.
Improved miniport driver interface that addresses the needs of high-end storage vendors, particularly host-based RAID and fibre channel vendors.

All vendors are encouraged to use Storport where possible, rather than the SCSI Port driver. Certain restrictions apply, however. Storport cannot be used with adapters or devices that do not support Plug and Play. All DMA devices must have bus-mastering DMA capability, because Storport does not support programmed I/O or subordinate-mode DMA. Other restrictions apply in regard to tagged queuing, autorequest sense, WMI support, the sort of SCSI inquiry data that devices must report, and booting directly from an adapter's ROM BIOS. For a detailed list of restrictions on the use of the Storport driver, see Requirements for Using Storport with an Adapter.

To better utilize the investment that vendors have made in SCSI Port miniport drivers, Storport follows the SCSI Port-miniport driver architecture with very few modifications. Changes to the SCSI Port driver interface were made in areas where new algorithms were able to produce measurable speed increases, or where it was necessary to add support for high-speed buses.
