HighPoint RocketU 1144E PCIe 2.0 x4 USB Controller 2X 6Gb/s E-SATA Ports and 2X USB 3.0 Type A Ports.

Introducing the
Highpoint Rocket 1144E: Versatile Connectivity - 5Gb/s USB 3.0 & 6Gb/s eSATA on Single HBA! The Rocket 1144E maximizes the performance potential of USB 3.0 and 6Gb/s SATA storage devices. The dual 5Gb/s USB 3.0 ports support all industry standard USB 3.0 devices while the dual 6Gb/s eSATA ports are optimized for today's fastest SATA SSD's and high-capacity hard drives. The Rocket 1144E is well suited for a wide-range of applications including storage expansion, personal media libraries, and backup solutions. Dedicated per port
Performance Architecture: The Rocket 1144E benefits from Highpoint's innovative per port performance architecture. Each device port is fully independent, and powered by a dedicated 5Gb/s USB 3.0 or 6Gb/s SATA controller. This revolutionary design ensures maximum performance for all USB 3.0 and 6Gb/s SATA devices. Uncompromised Storage Expansion for
PC & Mac Platforms: The Rocket 1144E supports represents the industry's most versatile 4-port HBA, and is capable of supporting all industry standard USB and SATA storage devices. The Rocket 1144E can be easily installed into any PCI-E 2.0 x4, x8 or x16 slot, and is fully compatible with PC and Mac computing platforms.
UAS Performance Boost: Maximizing the Performance Capability of
USB 3.0 devices: AS (USB Attached SCSI) is a computer protocol that is used to transfer data to and from USB storage devices. 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. USB 3.0 connections working in UASP mode result in higher transfer speeds and lower CPU utilization.
Thunderbolt Aware Enabled: The Rocket 1144E is a Thunderbolt Aware HBA, and is designed for use with Thunderbolt PCI-Express expansion devices and storage enclosures.
