Product Description

TerraMaster D5 Thunderbolt 3 RAID storage - More Power, More Speed.

Equipped with two Thunderbolt 3 interfaces, the TerraMaster D5 Thunderbolt 3 RAID storage enables users to connect with any USB device at 8 times the speed of USB3.0, while supporting full 4K video performance.

Boost Performance Using Hardware RAID

Software RAID consumes extensive resources on your computer system, which affects the efficiency of your other tasks. Moreover, unexpected power outages come with the substantial risk of data corruption for the backed up software RAID. TerraMaster’sD5 Thunderbolt 3 features professional-grade hardware RAID and on-board flash memory to provide faster, more efficient backup and restore capabilities, enhancing your performance and providing additional fail-safes.

Daisy-chain up to 6 devices (Only on Mac, not supported on Windows)

Capitalizing on the Thunderbolt 3 and DP interfaces, the D5 thunderbolt 3 supports multi-screen displays with up to 3 monitors or daisy-chain up to 6 devices. This is an ideal solution for multitaskers, especially when efficiency is the end goal. The Thunderbolt 2 devices with the daisy-chain function can also be daisy-chained to the D5 Thunderbolt 3.

Note: Daisy-chainning is compatible well on Mac, Windows has the compatibility issue and may crash.

To use the device, your system should satisfy the requirements below:

  • Operating System: 64-bit Windows 8/10 or later; MAC OS X 10.12 or Version later;
  • Hardware Requirement: CPU Intel i5 Quad-Core or higher;
  • Memory: Minimum 4GB;
  • Interface: Thunderbolt 3 or 2; If your device has only the USB ports, it will not be compatible.
  • Applicable Hard Drive: 3.5" SATA enterprise hard drive, SSHD hybrid hard drive, NAS hard drive (SATA III or above), or 2.5" SSD (SATA II or above).

Terra-Master TD-2 solved one issue but needs to be set at factory

Terra-Master TD-2 solved one issue but needs to be set at factory
The Terra-Master TD-2 unit is solid with some issues. It is built well, quiet (except for HD spinning) and solved my “improperly ejected” problem from another dock. However when I received it, I was unable to get it to recognize any of the drives tested. This was with multiple ports, cables, settings, and 4 different drives. After this frustrating start and an email to Terra-Master support, they responded the next day with the following suggestion:Step 1: Keep the device connected to the computer, powered on and diskless (no hard disks installed);Step 2: Check and ensure the pointer at the back of the device at the Single mode, then press and hold the “Reset” button for 10 seconds;Step 3: The hard disk indicators will be off, then keep the device powered on and install the hard disks;Step 4: The hard disks should be then showing up in Windows “Disk Management” or Mac “Disk Utility”. Please initialize and format the disks to use.I did everything except reformatting the drives and the drives appeared in my finder as they should. I then performed speed tests with Blackmagic Disk Speed Test and found similar read & write speeds to my other dock at about 500 MB/s and 140MB/s for a Samsung EVO 1TB SSD 8TB and a Western Digital HD respectively. The one problem that I was trying to fix with this enclosure was that of the disks ejecting during a backup of about 2TB from a Mac Pro that resulted in having to do the transfer in a piece-meal fashion. This dock allowed about 2.5TB to be backed up (in about 5hrs) with no eject errors. It also doesn’t seem to have problems even when the computer goes to sleep. BTW, all of these results were on a Mac Pro 2019 with older HDs and SSDs using the dock in single or non-RAID setup. Haven’t tested it for RAID function.With the exception of it not recognizing drives early, I am happy with the unit but it would reduce customer hassles and returns if they performed the above procedure in the factory.

5.0 out of 5 stars Etremely Fast and Silent !
Reviewed in the United States on October 17, 2019
Moved from Slapple to WIndows and wanted to take advantage of Thunderbolt 3 - what a drive ! Support answered all my geeky questions quickly. I'm buying another !
UPDATE **** 2 years later....
I ended up selling both of these drives on eBay for several reasons:
1 - Apparently having two D5s attached to my GigaByte Z390 caused a problem with Windows 10 that made the drives unreliable
2 - I have two other editing systems running Windows 10; 2 have Promise Pegasus 3 R6s. Both of those machines go to sleep with no issues. The PC sleeps and the drives power down, starting up again when the system wakes. The D5 will go to sleep but when the system wakes up the RAID crashes and has to rebuild itself. I use RAID 5 and once while I was trying to figure out what was causing this, I lost 2 drives, so, the RAID could not be rebuilt. The drives were fine after a low level format but the D5 obviously did something catastrophic to them when it tried to wake up. I contacted TM support and was told all RAID drives could not sleep. Radio silence, when I informed them about the Pegasus. I realize the Pegasus is 4 times the cost of the D5, but you get what you pay for !
3 - the HighPoint Tech Raid Utility is worthless, if you ask me, while the Promise Utility is smokin'.

Our PCs are on all the time to do backups and and remote in, etc; but, if you never have your computer sleep, the performance isn't terrible on the D5 and would do the job but the D5 also consumes quite a bit of power ( .26 KWH ) with the PC off and .38 KWH when it's on. At our rate that's 3.5 cents and hour. Hey, it adds up in the TCO...

TM support was polite albeit not offering any solutions for the driver or the sleep issue. We are very happy with the R6s and I wish I had not tried to save money on a budget enclosure...

4.0 out of 5 stars Excellent hardware RAID controller, great speed, beautiful design
Reviewed in the United States on March 29, 2019
TerraMaster D5-Thunderbolt 3 hardware RAID controller. 4 stars for excellent design, flexibility and incredible time saving speed that will get your backups done rapidly.
I love this RAID enclosure and controller. It certainly wins the good looks award for all of the DAS and NAS enclosures I looked at. For backups, I get write speeds of 160-220 mb/s with 5x12TB 7200 rpm Iron Wolf drives with RAID 0 via Thunderbolt 3. That's 4.5 TB of my Lightroom photo library backed up in 7 hrs- it used to take a day and a half, and with that painfully long time to backup via USB 3.1, backups did not get done nearly as often as is safe and prudent.
My goal was to use a pair of D5T3s- as a main photo library drive in RAID 10 with hot spare and the other for backup in RAID 0. But the reason I did not give this unit a 5 star is that they have not worked out the daisy chaining of drives in Windows yet. It is supposedly smooth in Mac and they are working hard with Microsoft to get the Thunderbolt daisy chaining worked out.
TerraMaster has excellent technical support and they spent many hours helping me get this set up. A non-geek can set this up and the RAID Controller software works well. But trying to get the daisy chain to work without frequent crashes was frustrating.
I expect it can be resolved shortly since it worked relatively smoothly with a single LaCie T3 drive. I will update if that happens. The speeds noted above are with the D5T3 daisy chained with the single T3 drive reading to the D5T3 in RAID 0.
In summary, this is a very good RAID unit with the very important RAID hardware [much better than Windows software RAID controller], beautiful design, and very fast Thunderbolt 3. When their daisy chaining for Thunderbolt 3 is ironed out, this will be the unit for both primary photo/video library and for backup. Remember, if you buy a RAID to be your primary library, you must have a backup. A RAID by itself is not backup!

Reviewed in the United Kingdom on October 29, 2023
Started off with one of these more than 2 years ago and expanded with time, daisy chaining they can copy to each other while i work. The simplicity is refreshing, raid 0 with modern HDD's gets near 500mb's per second which is fine for most of my work, 4k & 6k multicam editing etc. SSD's work great too and have gotten near 750mbps in raid 0 when ive needed it. When reviews say there are noisy they are talking about the HDD's that have been put in. The enclosure its self is basically silent when running SSD's. If you go onto their website, there is actually decent chat support. And lastly the two bay enclosure is reasonably portable which i have taken advantage of more than i thought.
