USB 3.0 to 4-Bay SATA 6Gbps Hard Drive Docking
Station w/ UASP & Dual Fans - 2.5/3.5in SSD /
HDD Dock
Product ID: SDOCK4U33
The SDOCK4U33 four-bay 2.5/3.5" SATA HDD / SSD docking station lets you dock and swap four drives
from your desktop or laptop computer simultaneously, using a single USB port.
Get the most out of your SATA III (Gbps) solid state drives and hybrid drives with this UASP (USB
Attached SCSI Protocol) enhanced hard drive docking station. With performance up to 70% faster than
conventional USB 3.0 when paired with a UASP-enabled host controller, UASP ensures high performance
by reducing bottleneck. See our UASP testing results below for further details.
The hard drive dock features independently-powered SATA connectors for each individual drive, ensuring
you can operate drives separately. This gives you the freedom to hot-swap one drive while transferring
data to another, saving you time. Plus, the built-in fans keep your drives running cool, ensuring optimal
performance and helps to prevent premature drive failure.

Extend the value of this hard drive docking station further with the addition of our SATA to IDE Hard Drive
Adapter (SAT2IDEADP), allowing easy insertion of any 2.5 or 3.5in. IDE hard drive into a SATA hard drive
dock.
To ensure compatibility with your computer system, the SDOCK4U33 supports all of the leading operating
systems, including: Microsoft Windows® (8/7/Vista/XP/Server 2008/Server 2003), Apple® OSX
(10.9/10.8/10.7/10.6), Linux, and Google Chrome OS™.
SDOCK4U33 is backed by a StarTech.com 2-year warranty and free lifetime technical support.
Improved Performance with UASP
UASP is supported in Windows 8, Mac OSX (10.8 or above), and Linux. In testing, UASP performs with a
70% faster read speed and 40% faster write speed over traditional USB 3.0 at peak performance.
At the same peak in testing UASP also shows an
80% reduction in required processor resources.
Testing results were obtained using an Intel® Ivy
Bridge system, a UASP-enabled StarTech.com
Enclosure, and a SATA III solid state drive.
