TerraMaster TD2 Design and Build
The TD2 Thunderbolt 3 is designed with a compact form factor and a streamlined minimalist aesthetic. Its aluminum casing offers durability and the handle on top is a unique feature. In front, there is a single button for the power, three LED light indicators, and the two drives. The drive bays slide open and support hot swapping.

TerraMaster TD2 Performance
To test the performance of the TerraMaster TD2 Thunderbolt 3 we will be looking at BlackMagic on a current generation MacBook Air and IOMeter on a HP Studio x360. We used two enterprise SATA SSDs from. SK hynix, the SE4011 2TB-class drives.
For Blackmagic the TerraMaster TD2 Thunderbolt 3 was able to hit 710 MB/s read and 502.1 MB/s write. With these results the TD2 significantly exceeded it’s claimed write performance and was close to it’s claimed read performance.
Moving on to IOMeter, we ran 1 thread and 16 thread testing. We’ll start with 1 thread performance. When looking at 2MB sequential the TerraMaster TD2 hit 755.98 MB/s read and 367.78 MB/s write. Looking at 2MB random speeds, we saw 669.52 MB/s read and 365.91 MB/s write. In random 4K the TD2 hit 4,668.97 IOPS read and 12,272.91 IOPS write.
Now we”ll dive into 16 thread performance. For 2MB sequential we saw 786.79 MB/s read and 398.86 MB/s write. For 2MB random we saw 781.01 MB/s read and 398.21 MB/s write. Finally, for random 4K speeds hit 65,946.30 IOPS and 54,235.25 IOPS respectively for read and write.
Conclusion
The TerraMaster TD2 Thunderbolt 3 is a compact dual-bay RAID storage device. It is aimed at creative professionals in the video editing market and is suited to support demanding applications including 4K video editing and 4K streaming. With an individual capacity up to 32TB and a daisy chain scalability up to 168 TB this product certainly has the capacity to support such endeavors. It also offers flexibility highlighted by multiple RAID support, compatibility with multiple drive form factors including 3.5” HDDs, 2.5” HDDs and 2.5” SSDs, and universal USB-C Thunderbolt 3 connectivity.
Diving into performance, we tested the TerraMaster TD2 with both Blackmagic and IOMeter. For Blackmagic the TerraMaster TD2 Thunderbolt 3 was able to hit 710 MB/s read and 502.1 MB/s write. In IOMeter, we ran 1 thread and 16 thread testing. Overall the TD2 did well producing close to TerraMaster’s performance claims. Additionally, there wasn’t much dropoff when comparing our sequential and random results which is always a good thing to see. A place where the TD2 fell behind a bit is in 1 thread 2MB random testing where it produced 669.52 MB/s read. However it shined in a great many places including Blackmagic and our IOMeter 16 thread testing where we saw 786.79 MB/s read and 398.86 MB/s write in 2MB sequential and 65,946.30 IOPS and 54,235.25 IOPS read and write respectively for random 4K.
Overall being an easy to configure and transport external storage solution, the TerraMaster TD2 Thunderbolt 3 platform has a lot to offer content creators and other individuals on the go. Expanding beyond just storage connectivity, the dock also gives you an external monitor hookup to further increase productivity. This is very important for notebooks that might only offer a single USB-C connection, so you don’t need to choose between storage or an external display.
