The USB 3.0 to Dual 2.5/3.5" HDD/SSD Docking Station with UASP from StarTech allows you to dock and swap drives from your desktop or laptop computer simultaneously using a single USB port.

Enhanced with UASP (USB Attached SCSI Protocol), this hard drive docking station lets you get the most out of drive technologies, such as SATA III (6 Gbps), solid state drives (SSD), and hybrid drives, with performance up to 70% faster than conventional USB 3.0 when paired with a UASP-enabled host controller. UASP is supported in Windows 8, Mac OS X (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. UASP also shows an 80% reduction in required processor resources. Please note that StarTech achieved these results by testing the docking station with a computer that has a 3rd generation Ivy Bridge Intel processor and a SATA III solid state drive.

The hard drive dock features independent power buttons for each drive, ensuring that you can operate each hard drive separately. This gives you the freedom to hot-swap one drive while transferring data to another.

To ensure compatibility with your computer system, this docking station supports a wide variety of operating systems, such as Microsoft Windows, Mac OS X, Linux, and Google Chrome OS.

Australian Shipping Via DHL
DHL offers a great express shipping service to Australia from New Zealand. We are proud to be able to offer express shipping to main cities on the east coast of Australia, within the same timeframe ( If not quicker ) than local Australian courier companies. Prior to the Covid-19 outbreak, service standards for these main centers was overnight. However these services have been impacted greatly, and as such the overnight service has been suspended. Overnight shipping will likely resume once things have returned to normal.

Qualifying main centers include:

  • Brisbane
  • Sydney
  • Adelaide

Whilst this service is extremely efficient and will likely be delivered within 1-2 days 99.9% of the time, it cannot be guaranteed. In the case where something were to go wrong with your delivery and it doesn’t arrive within the specified time frame, in most cases it will be delivered by the next day.

While not all major cities are eligible for overnight delivery, they still benefit from this great service. Other centers throughout Australia will have a typical delivery ETA of 2-4 days. (Excluding rural delivery address where this ETA can be extended to an additional three or more days).

If you require urgent shipping and you don’t reside in one of the cities stated above, please contact us and we can find a solution that works best for you.

Please Note: Shipping via DHL is not available to PO boxes and/ or parcel boxes etc.
