Anker USB 3.0 and eSATA To SATA External Hard Drive Docking Station for 2.5 / 3.5in HDD and SSD


Product Description

SuperSpeed. Versatile. Tool-free. A premium dock for your 2.5” and 3.5” hard and solid state drives.

2.5” and 3.5” HDD/SSD compatible.

Due to its unique spring design, this docking station holds both your 2.5” and 3.5” HDD or SSD firmly in place. Moreover, the e-SATA interface accommodates all SATA standards (SATA, SATA II, SATA III).

SuperSpeed up to 5Gbps.

Equipped with both USB 3.0 and e-SATA ports, this docking station delivers SuperSpeed of up to 5Gbps (3Gbps for the e-SATA port). Transfer your data in just minutes, instead of hours and have more time to do what you want.

Ease of use.

Instead of complicated screws to work with, our docking station just snaps in place, holding your hard drive firmly and securely. The LED indicator with two colors reveals power status and data activity. What’s more, a power button lets you disconnect to protect your data when not in use, instead of unplugging the power cable.

For optimal use

• Your drive cannot be accessed via both eSATA and USB 3.0 ports at the same time. If both are connected, only the eSATA-connected computer will be recognized and interact with the drive.
• Do not attempt to remove your HDD or SSD device while it is active. Please power off the docking station before removing. • Active use may result in expected surface temperatures up to 50°C or 120°F. Please take caution when removing your drive.
• The following Seagate SATA drive models will require a firmware upgrade, downloadable from the Seagate official site, before use:
• Note for Mountain Lion (10.8) users: If you are experiencing formatting problems, please note that this is unrelated to our dock’s performance. You may try reformatting your disk to the FAT32 format on using another operating system.

  • SATA Exterenal Drive dock. Works well.
  • Good so far, good transfer speeds when using a 3.0 port, first use was copy two 2.5 spin drives to SSD drives using another enclosure from the source drives. No errors and the SSD's are working as expected.This is a nice unit for both 2.5 and 3.5 spin and SSD drives. My primary use will be to read drives, besides a copy drive's from time to time.

  • Great product. Plug and play simple to use
  • Great product. Plug and play simple to use. My only trivia issue was when It sits idle it goes to sleep? disconnects the usb which causes it to wake up and reconnect to usb and starts rediscovery over again. There is probably a simple fix in the power settings but to lazy to look for it. I was able to use it to backup 500gb on my NAS at usb 2.0 speeds was did a consistent transfer at about 25mb/s and was completely stable for the 8ish hours of the transfer. Now I just need to upgrade my PCs to usb3.0 to take advantage of the speed.

Customer FAQ

Q1.  Some hard disks from Seagate are unable to be identified. Why is this?
There's a batch of hard disks produced by Seagate that has compatibility issues with their firmware. You can update your firmware on Seagate’s official website to solve this problem (
The serial numbers of the defective products are listed below for your reference:
    ST3000DM001/9YN166/3TB     ST2500DM001/9YN16L/2.5TB     ST2000DM001/9YN164/2TB     ST1000DM003/9YN162/1TB     ST500DM005
Q2.  Why am I unable to reach SATA-III transfer rates of up to 6Gbps?
While many of our SATA devices can detect and transfer data for SATA III disks, e-SATA cables limit these transfer speeds to 3Gbps. We are currently looking into upgrade options.
Q3.  Why is the transfer rate so much slower than the 5Gbps promoted?
The USB 3.0 transfer rate is 5Gbps and has a theoretical transfer speed of 500MB/s which is about 8 times faster than the USB 2.0 transfer rate of 480Mb/s with theoretical transfer speed of 60MB/s.
There are numerous variables that will affect USB transfer rate including data source and destination and file type. With all reasonable usage environments taken into account USB 3.0 can achieve average transfer speeds about 3 times faster than that of USB 2.0.
Q4.  Why doesn’t my hard drive fit into the docking station?
The docking station is only compatible with e-SATA hard drives. If the drive is another specification then it won't fit.
Q5.  Why isn’t the docking station visible under “MY COMPUTER” when I plug it in?
This may be caused by one of the two scenarios below:
a. Conflicting drive names. If the hard drive has been used on a different computer and was given the name C: then it will cause conflicts if the computer it is currently being used with already has a drive named C:.

Solution: Go to “COMPUTER MANAGEMENT”, select “DISK MANAGEMENT,” locate the external hard drive, and then assign a different name to it.

b. The hard drive is configured to operate with another OS:

Solution: Format the hard drive.
- Quick formatting: Good for a new hard drive. Since no data is stored, there is not much “clean up” needed.
- Full formatting: Good for a used hard drive. Remember, this method will wipe ALL data on the hard drive so please make sure important files are backed up.
Q6.  Why is the hard disk disconnecting from the computer during data transfer?
Make sure the device is connected to a power source to ensure a stable power supple.
a. Try not to move the docking station during data transfer as it can loosen the cables in the ports and interrupt transfer.
b. Ensure the cable you're using is less than 1m long.
Q7.  How do I use the Y-shaped cable for the USB 3.0 HDD External Enclosure?
a. When using the USB 3.0 port to transfer data: connect the USB-B cable to the USB interface on the docking station, then connect the USB-A cable to the USB interface on your computer to supply power.
b. When using the e-SATA port to transfer data: connect one end of the e-SATA cable to the e-SATA interface on the docking station, then connect the other end to the e-SATA interface on your computer. Connect the USB 3.0 or USB 2.0 cable to the USB port on your computer to supply power.
Q8.  Can I use the USB 3.0 and e-SATA ports together to transfer data?
No, you can’t. When both ports are in use, only the e-SATA port will be used to transfer data, while the USB 3.0 port will simply be used to supply power.
Q9.  Can I use the USB 3.0 and e-SATA ports on the docking station at the same time?
If the USB 3.0 and e-SATA ports are connected at the same time (whether to two computers or one) the docking station will give priority to the e-SATA port. The station is not able to provide functionality to both ports at the same time.

3 TB only show 1.81 TB


I have a WD 3TB Red. Model No. is: WD30EFRX.

When I dock with Anker USB 3.0 and eSATA Docking Staion. I only see 1.81 TB.

I am running Windows 7.1. I have checked it is GPT. It shows up in windows as 1.81 TB as well.

Any ideas?


Many Thanks,

Could you check the partition? Also if you see the same thing could you unplug the HDD unplug the power to the dock and replug everything?

Mr. Gurney

I have your USB 3.0/e-Sata docking station, and it worked for a while but now when I plug-in a HD, it doesn't get listed. Am running Windows 7, and already read your FAQ that suggested to use the system tools, etc. I've tried several different HD's but they do not list in windows explorer. Can you help?

Unexpected reboots, Yosemite

I just bought a new ExpressCard/34 for my Macbook Pro running Yosemite (10.10.2) and I struggled during 3 days to have it working on whether eSATA or USB 3.0 using the Anker USB 3.0 and eSATA To SATA External Hard Drive Docking Station.

My Macbook Pro was rebooting each time I was trying to copy data to the external hard drive, I tried both a standard HDD and an SSD with no luck. The symptom was as follow:

- Initiate data copy to external drive...
- Calculating....
- System freeze, no response from keyboard or mouse
- Rebooting with no error message

I had to repair the external volume each time.

I finally fixed my issue by disabling "Trim Enabler" which I had enabled for my "non apple" internal SSD drive. Since then, I enjoy copying data with no more unexpected reboot.

I have a Dell Inspiron 15 and I was wondering. I'm replacing my HDD on my Desktop. I need to backup all the data. So will this work for it? It's a 3.5 Inch 7200 RPM Hitachi SATA 3 drive. Will the dock work or will I need to plug in the molex adaptor cable from the PSU to the HDD. Thanks.

Docking Station Not Found
My Anker hard drive docking station does not appear in my "My Compueter" or my devices nor is it listed on the Computer Management>Disk Managment tool. I have tried the eSata and USB 3.0 connections (but not at the same time)  but it is not seen by my computer for either of them. Please can you tell em how I install the docking station so my computer can see it.

have you installed the drivers, (if needed), from the Anker site?
Reply Report as spam Jul 20, 2014 at 6:12 AM

It may be caused by a conflict in drive names or the hard drive needs formatting.

Maximum Hard Drive Capacity
Hello,I purchased an Anker USB 3.0 and eSATA To SATA External Hard Drive Docking Station for 2.5 / 3.5in HDD and SSD. I was reading the documentation and it says the maximum HDD support is 3TB, however on Amazon it states 4TB. I bought it because of the 4TB support. I have 4 - 4TB hard drives that I need to use for this. I tried plugging in one of my 4TB hard drives but my computer does not recognize it. What is the maximum hard drive size for the 6618 SUS3?Thank you,Shane

Sorry for the confusion on this, the latest manual actually states that the docking station can support up to 4TB to go along with the Amazon listing.

Auto Power On
Hi,I use Crashplan to back up to a hard drive connected to this Anker dock. If there is a power outage, I usually forget to turn the dock back on, until Crashplan sends me an email complaining it can't access the hard drive. Is there any way to have the dock power on automatically when the power comes back on? Thanks
Replies(1) Collapse Report as spam May 29, 2014 at 8:22 PM

Unfortunately there isn't a setting for the dock to auto power-on when it receives power.
