USB 3.0 to eSATA mini Adapter

Discontinued and replaced by ADU31ESP


The USB 3.0 to eSATA Mini Adapter is the simplest solution for connecting any eSATA storage device to the latest USB 3.0 (Superspeed) or the ubiquitous USB 2.0 port on any Notebook, Desktop, server or computing equipment. This adapter does not require any driver or special software and is powered directly from the USB port. The small size makes this adapter a handy accessory for wide range of storage applications.

Illustration of various eSATA devices that can be attached to this adapter

  • Connect any eSATA storage to any USB port
  • Support USB 3.0 / USB 2.0 / USB 1.1
  • Maximum transfer rate:
    • 5 Gbps - USB 3.0 super speed
    • 480 Mbps - USB 2.0 high speed
    • 12 Mbps - USB 1.1
  • Compatible with external hard drive, SSD, optical drive with eSATA interface
  • Great for connecting Addonics RAID Tower, RAID Rack or eSATA RAID storage to USB 3.0 or 2.0 port
  • Maximum drive size over 4TB
    (for older Windows OS that does not support GPT partition, drive size over 2TB can be partitioned in MBR in 4K sector* using the model ADU3ESAM-X)
  • Power directly from USB port. No power adapter is required
  • No driver or software required
  • LED indicator for power and drive acces
  • Supported OS - All Windows OS except for Windows 98SE or older, Mac OS X or later and Linux kernel 2.4 or later

* In order to install drive size over 2TB, the OS must support GPT drive partition in standard 512 bytes sector. All modern OS such as Windows 7 and later, Mac OS X or the latest LInux Kernel support GPT drive partition and should use the standard model ADU3ESAM

For older Windows XP system that does not support GPT drive partition, the hard drive over 2TB must be partitioned in MBR with 4K sector. In this case, you will need to use the model ADU3ESAM-X. However Linux and Mac OS do not support drive with 4K partition. So this will limit the drive to be used in the Windows XP system only. Drive partitioned in 4K sector will not work with any Addonics NAS adapters as all these devices use Linux OS.
