Thermaltake BlacX Duet USB 3.0

Thermaltake BlacX Duet USB 3.0 Review

I‘m not new when it comes to Thermaltake duet docking stations.  I own an older one that has E-SATA and USB 2.0.  The reason why I bought this one is the fact I can transfer files faster. My older one needs a bit of work since I broke the USB port on the dock.  I can say since I’ve owned the older one for years and haven’t had an issue besides breaking the port, I’m very confident this one is great too.

I’ll be doing some speed tests with the docking station below.  Make sure to check them out.
You can view this docking station on the original website here: //



  • Box (Unopened) 756 grams / 1.67 pounds
  • Dock 400 grams / 0.88 pounds
  • Power Supply 170 grams / 0.37 pounds
  • Cord 36 grams / 0.079 pounds



All Tests were done on the Alienware Aurora-R4

I want to note:
I did have an issue with CrystalDiskMark on the Seagate 7200 RPM Laptop Drive benchmarking the speeds.   The program stopped responding and I was forced to end task and tried to eject USB to SATA bridge.  Unfortunately, that stopped working too.  I turned off the dock and turned it back on.  That did the trick and I was able to benchmark the drive.  It only happened once.

Well, I got higher Read & Write Speeds on the dock than on the Motherboard.  I wonder if that’s got anything to do with my SATA adapter to extend the 2.5 to a 3.5 drive bay.
Either way,  these are good examples for you to have somewhat an understanding on the docks Read & Write Speeds.

    f. Wait until OS completes all installations before usage.
  4. Creating a Partition
    If you want to operate the HDD Docking Station on both Windows and Mac OS, it is recommended to format the hard drive in Windows and choose FAT 32 file format.
    Do not change set the partitions or format hard drive. Otherwise, Windows OS will not be able to recognize the hard drive.g. For Windows XP/Vista/7 Users:
    – Right click on “My Computer” and choose
    – Under “Storage” on the LEFT panel, select “Disk Management”.
    – Right Click on the newly added hard drive and choose New Partition.
    – Follow the onscreen New Partition Wizard to setup Partition and Format hard drive.
    (Be Sure to Assign a Drive Letter).
    – Once Partition and Format are completed, the hard drive is ready to use.h. For Mac OS 9.2 & earlier version:
    OS does not support partition creation for the external hard drive.
    In order to create a partition for an external hard drive with Mac OS 9.2 & earlier, the user will need to purchase additional 3rd party software to create hard drive partition.i. For Mac OS X:
    Simply use the Disk Utility to Partition and Format external hard drive as follows:
    – Select Disk Utilities in the utilities folder.
    – Choose newly added external drive and format it.

Do you own one?  If so what do you think about it?
