TerraMaster D2 Clone: Introduction
The TerraMaster D2 Clone is a hard drive duplicator capable of mounting two independent 2.5in SSD or 3.5in HDD storage drives, allowing users to clone from one drive to another of equal or greater capacity. This peripheral has an MSRP of $119.99 USD.
The D2 Clone uses a USB 3.1 Type-C connection to your PC, plus no drivers are necessary. For cloning you don’t even need a PC or any other device, just the D2 Clone itself and two drives. Simply press the power button a couple times on D2 Cloner and wait while the peripheral does its job. The indicator lights tell you the status of the storage drives, displaying the completion percentage of the cloning process.
TerraMaster D2 Clone: Closer Look
The TerraMaster D2 Clone is rated for up to 550MB/sec for SSD cloning, and up to 200MB/sec for HDD cloning. Drive capacities of up to 18TB are supported for up to a combined 36TB maximum total capacity, but this model only supports SINGLE disk mode so you really get two 18TB storage options. The packaging is similar to other TerraMaster products we’ve seen, only beige instead of the standard blue. A sticker on the side panel provides a description of the product contained within. Foam adequately protects the D2 Clone inside the packaging, with all of the other contents in another small cardboard box.
The D2 Cloner looks like it uses the same housing as the F2-422 I reviewed back in October 2020, except with a different front and rear panel equipped. The front panel has eight LEDs for its readout, and the HDD LEDs will turn green or orange depending on drive health and status. The power button also serves to operate the cloning procedure: double clicking will get the process started, but cloning isn’t executed until you click it a third time within 10 seconds of the double click. After 10 seconds, it aborts the cloning procedure attempt if you don’t click again.
You’ll need to use Bay 1 for the source drive, and Bay 2 for the drive being cloned to. All data on drive 2 will be lost after cloning, so keep that in mind! You don’t have to worry about formatting the second drive beforehand, as the D2 Clone will handle all preparations! If you choose to clone to a storage drive with a greater capacity, the extra capacity will be unassigned so you can later assign it or extend the storage of cloned partition in your OS.
At the bottom of the D2 Clone are ventilation slots, with rubber feet to add clearance. The housing is a sturdy metal design with a nice textured surface, and TerraMaster logos on both sides. The drive holders are plastic and have multiple screw holes for both 2.5in and 3.5in drives.
The circuitry of the D2 Clone is a lot simpler than that of the F2-422 or F5-221 that I looked at recently, which makes sense. The D2 Clone only offers USB connectivity, and acting as a USB host is a lot less intensive than serving or streaming media as a NAS! An ASMedia ASM1156 chipset is the heart of the operation here, providing both the cloning capabilities, SMART drive monitoring, fan control, and USB to SATA host conversion. It can also support JBOD, but TerraMaster hasn’t elected to add that as a feature here.
TerraMaster D2 Clone: Testing
Testing and using the TerraMaster D2 Clone is extremly easy and straightforward! I first set out to clone a Windows 10 240GB SSD to a 1TB SSD, an upgrade that would seem desirable and likely for most users, thanks in part to the dropping cost per gigabyte of SSD technology. My SSD had roughly 140GB of data on it out of the 240GB capacity (closer to 223GB when formatted), and it took 38 minutes for the D2 Clone to perform an exact clone to the 1TB SSD! That equates to around 3.7 GB/minute or 491.2 Mbit/s — or 61.4 MB/s, but that includes drive formatting time so the actual rate was likely higher.
After cloning was complete, I had to disconnect the old drive because Windows doesn’t like it when two drives have the same disk signature. After I removed the old drive, I was able to mount the new 1TB SSD through the D2 Clone which can serve as a USB storage device for one or two drives (with different signatures). I then tested the transfer rates to the 1TB SSD, and getting mid-400s MB/s read and write was a nice surprise. I didn’t optimize the test run because I wanted to see how well the D2 Clone would work in a typical environment, and I wasn’t disappointed!

TerraMaster D2 Clone: Conclusion
Don’t be fooled by the name, the D2 Clone is also very capable as a Direct Attached Storage host! It easily provides access for up to two separate SATA storage drives over high speed USB 3.1, all without software. Cloning drives is also done without software, and the process really is as easy as a few clicks of a button. All of those great features for the low MSRP of $119.99 USD.
The TerraMaster D2 Clone comes with everything you need to get started right out of the box. It has plenty of screws for both 2.5in and 3.5in storage devices, a USB 3.1 Gen1 Type-A to Type-C cable, a power adapter, drive labels, and a nice handy screwdriver! The only minor inconvenience I could find worth mentioning is that having to use screws to mount both the drives makes swapping drives slightly tedious. A tool free drive bay would be even more convenient, but likely would have added to the cost. Using screws for mounting is natural for most 2+ drive storage options, and you’ll only notice this if you swap drives a lot! If you rarely clone multiple drives or don’t plan on changing drives often for DAS you won’t even notice.
Cloning drives was very straight forward — put the drive you want to clone in bay 1, the drive with equal or greater capacity to be cloned to in bay 2, power on the D2 Clone, double tap power to start the cloning process, and tap it once more to confirm you want to start cloning. Then sit back and relax while the D2 Clone does all the work, you don’t even have to format or delete anything at all! No drivers are needed for cloning or USB storage, and my devices immediately recognized the D2 Clone and the installed drives! One caveat I didn’t see mentioned is that after cloning is complete, some systems will only display one drive because both drives will have the same exact disk signatures. You can change the second drives’ disk signature if you need to access both at the same time, or just unplug one or the other to switch between them.
The D2 Clone worked great a Direct Attached Storage host! I would recommend it readily to anyone looking for such functionality, with the added bonus of the cloning capability. For the price the D2 Clone is very competitive with the D2-310 which has an MSRP of $159.99 USD, which lacks cloning capabilities but can do RAID 0/1/JBOD and SINGLE modes. The D2 Clone is very inexpensive, packed full of great features, and is extremely simple to use.
