RocketStor 5422: USB 3.0 UAS Enabled
Maximizing the Performance Capability of SATA Storage over
USB 3.0 Connectivity
The RocketStor 5422 can deliver unprecedented levels of storage performance when
paired with UAS capable USB 3.0 controllers and HBA's, such as the RocketU 1144C.
UAS enables USB 3.0 devices to store and process multiple
commands in parallel; significantly reducing wait time and streamlining data transfers.
The speed and efficiency advantages provided by UAS technology are ideal for
multi-tasking and performance-hungry applications.
UAS (USB Attached SCSI) is a computer protocol that is used to transfer data to and from USB storage devices such as hard drives, solid state drives (SSDs) and thumb/flash drives. UAS is dependent on the USB protocol, and utilizes the standard SCSI command set.
UAS offers maximized bandwidth utilization, and can handle multiple data transfer requests simultaneously, unlike the slower queue system of BOT (Bulk Only Transport), which only provides single-task commands ??each task must complete before the next begins. As a result, USB 3.0 connections working in UASP mode result in higher transfer speeds and lower CPU utilization. UAS clears data queues faster, which results in smoother-operating PC's.
