USB Attached SCSI Wikipedia. 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. Use of UAS generally provides faster transfers compared to the older USB Mass Storage Bulk Only Transport BOT drivers. UAS was introduced as part of the USB 3. Cheetah 10K. 6 SCSI Product Manual, Rev. D 1 1. 0 Scope This manual describes Seagate Technology LLC, Cheetah 10K. SCSI disc drives.

UAS drivers generally provide faster transfers when compared to the older USB Mass Storage Bulk Only Transport BOT protocol drivers. Although UAS was added in the USB 3. USB 2. 0 speeds, assuming compatible hardware. When used with an SSD, UAS is considerably faster than BOT for random reads and writes, but still well below the speed of a native SATA 3 interface 6 Gbits. Hardware supporteditA brief hardware roundup in July 2. Semi. Accurate found that Gigabyte Technology had introduced working UAS drivers for their boards using NECRenesas chips, and thaton the hardware level at leastthe Lucid. Ab Tutor Control By Brandon Strike there. Port USB 3. 00 and USB3. Symwave SW6. 31. 5, Texas Instruments TUSB9. VLI VL7. 00 controllers all support UASP, while as far as we could find, the ASMedia ASM1. ASM1. 05. 1E as well as the Fujitsu MB8. C3. 0A doesnt. 1A comparative performance review by VR Zone in August 2. NECRenesas chips had UAS working drivers. The same Renesas UAS driver for Windows also works with AMDs A7. M and A7. 5 Fusion Controller Hubs,7 the USB part of which was co developed by AMD and Renesas. In October 2. ASMedia chips had gained driver support as well they had support on the hardware side before. Fujitsu lists some higher end chips like the MB8. C3. 11. A that do support UAS. As for support by Intel Platform Controller Hub PCH, an article in My. CE notes The native Intel USB3 UASP solution is only supported under Windows 8. To further complicate matters, not all Z7. USB3 UASP. A license is required to implement UASP, and not all motherboard manufacturers are prepared to pass on the extra cost of this license to the end user. Operating system supporteditMicrosoft added native support for UAS to Windows 8. Drives supporting UAS load Uaspstor. Usbstor. sys. 1. 3 Windows 8 supports UAS by default over USB 2. UAS drivers and products are certified by Microsoft using the Windows Hardware Certification Kit. Apple added native support for UAS to OS X 1. Mountain Lion drives using UAS show up in Apple menu About This Mac System Information Software Extensions as IOUSBAttached. SCSI or IOUSBMass. Storage. UASDriver, depending on the version of OS X Loaded Yes. Drives listed with Loaded No are defaulting the older, slower Bulk Only Transport BOT mode. This may occur if the drives USB controller, the Macs USB port, or any attached USB hub doesnt support UASP mode. Designed to directly address the failings of the USB mass storage device class bulk only transports BOT. Enables command queuing and out of order completions for USB mass storage devices.
