Review of the Terramaster D8 Hybrid Storage System

What IS the D8 Hybrid and why is this brand’s newest device getting a lot of media attention of late? Terramaster has been a name in the world of NAS for quite a few years, but what about DAS? Unlike Network Attached Storage, Direct Attached Storage is something that is way, WAY more common and to try and stretch your muscles in this market requires something a little special. It would be unfair to say that Terramaster are new to this market, as they have actually been in this market with numerous USB and Thunderbolt solutions since around 2018/2019. Some of these were RAID enabled, some of them JBOD and thanks to their NAS systems being supporting USB Expansions, this has helped them create a neat crossover between their portfolio of devices. However, what can Terramater bring to the table in the heavy saturated world of USB storage? Well, the D8 is trying something different, with it’s 4 HDD and 4 NVMe USB-C 10Gb connected storage that is half JBOD (loose drives) and half RAID (supporting a mirror RAID on 2x HDDs). There are certainly pros and cons here, putting this much hybrid storage behind a USB connection, as well as the benefits and drawbacks of reliance of a client machine to manage the larger RAID options out there, but the burning question is… is the D8 Hybrid actually any good? Let’s discuss it in today’s review.

Introduction to the TerraMaster D8 Hybrid

The TerraMaster D8 Hybrid is engineered to cater to the evolving demands of personal and small business storage by amalgamating traditional hard disk drives (HDDs) with the swift, modern NVMe solid-state drives (SSDs).

 

This system includes four versatile SATA bays that support both 3.5″ and 2.5″ drives and four M.2 NVMe slots, offering a broad spectrum of storage options. It utilizes USB 3.2 Gen 2 connectivity, capable of reaching speeds up to 1000 MB/s. However, this setup prompts a discussion about the possible limitations of USB connectivity when used with high-performance storage technologies, potentially creating bottlenecks that could affect data transfer speeds.

Exploring the Design and Build

The D8 Hybrid showcases a durable and user-friendly design consistent with Terramaster’s latest NAS models. The system facilitates easy installation of drives with its tool-free “click and load” mechanism, suitable even for users without technical expertise.

The operational noise level is moderately low, which is a crucial consideration for use in shared spaces like small offices or home environments.

The storage solution accommodates up to four HDDs and four NVMe SSDs but opts out of including faster interface technologies such as Thunderbolt to maintain an affordable price point. This choice might restrict the performance potential of the system but makes the D8 Hybrid more accessible financially to a broader audience.

ASMedia and Realtek are two prominent players in the semiconductor industry, particularly known for their contributions to the development of chips that handle data connectivity and processing in various electronic devices.

ASMedia, a subsidiary of ASUS, specializes in high-speed interface technology, particularly USB and PCIe bridge solutions. Notably, their chips are pivotal in enhancing the performance of USB connections. For example, the ASM3042 is a significant advancement in their USB controller lineup, bridging PCI Express to USB3.2 and providing support for legacy USB functions. This chip showcases ASMedia’s capability to deliver high bandwidth and efficient power management, essential for maintaining low power consumption in various devices

In 2022, ASMedia became one of the first to introduce a USB4 host-controller, the ASM4242, designed to support high data transmission speeds up to 64 Gbps, making it backward compatible with Thunderbolt 3 and other protocols. The incorporation of ASMedia’s ASM4242, a high-performance USB4 host controller, into a device configuration represents a significant step towards future-proofing data transfer capabilities. The ASM4242 supports up to 64 Gbps of bandwidth, providing a robust solution for high-speed data, video, and power transmission over a single USB connection. This level of integration ensures that devices are not only meeting current standards but are also prepared for next-generation needs, with backward compatibility ensuring a broad range of device support.

Realtek’s contributions, while more commonly associated with their audio and network solutions, also extend to data interface technologies. Realtek chips are crucial for managing data transmission and ensuring compatibility across a vast ecosystem of computing and multimedia devices.

Their technology helps to stabilize and optimize the data flow, critical for the functionality of hybrid storage systems where data integrity and speed are paramount.

Detailed Performance Assessment

The performance of the D8 Hybrid was meticulously tested under various configurations to truly understand its capabilities and limitations. Configuring the device with two Seagate 24TB Ironwolf Pro Series HDDs in a RAID 0 setup, the system demonstrated robust performance with peak read/write speeds reaching 551/540MB/s.

Next up, to put this into perspective (and measure what that RAID 0 actually provided vs singular use), I ran the same tests with a single 24TB HDD. The results were notable and though unsurprisingly half that of the RAID 0 Dual Disk pool, did also give you a nice idea of what full hardware RAID on this device (or an externally managed RAID Controller/OS-RAID) could have given us.

Finally, I ran the same tests on a single M.2 NVMe SSD in Slot #1 if the system (a Kingston KC3000 M.2 NVMe) and the results was practical full saturation of the 10G USB connection. If we had used an external RAID controller/OS-RAID, we still would not have been able to escape the USB 3.2 Gen 2 1,000MB/s maximum,but it could have improved IOPS/latency further.

We have to look at this device as a JBOD (with a hint of a mirrored RAID) and therefore scale back our expectations a bit. With that in mind, I am happy with what the D8 Hybrid can do without a RAID in place. I could have managed this with my windows client and thrown on a few different RAID’s using software (softRAID or even just Disk Management and stripe etc), but that would limit the results to just my own system/setup. Overall, these numbers suggest a careful balance between performance and cost, ensuring adequate speed for standard tasks without the premium price tag associated with higher-end interfaces like Thunderbolt.

Is This a Comparative Market?

The D8 Hybrid is strategically positioned in the market to appeal to users who prioritize reliable performance over cutting-edge speed. It serves well for small to medium business applications, home offices, and creative professionals who require a dependable storage solution. The device offers an appealing alternative to more expensive options by providing sufficient speed for everyday tasks, including data backup and accessing large files, without compromising on quality or reliability.

Its cost-effectiveness paired with versatile storage capabilities makes the D8 Hybrid a formidable competitor in the hybrid storage market. It’s particularly attractive for budget-conscious buyers who still require a robust storage solution that can handle a mix of data types and usage scenarios.

Final Verdict and Conclusion of the Terramaster D8 Hybrid

      1. Okay, been looking at the Terramasters on Amazon and no matter what they all seem to have over 10% in bad reviews, |I have many a external drive and want something reliable and even the two main ones have their bad bits as well as being OTT cost wise for just a bunch of disk storage. it’s a minefield to a degree.

      3. I have a ROG XG Mobile dock with a D5 attached for when I put my flow 13 on the desk so I can have my steam library sitting ready. I only have a 3.1 Gen 2 USB port available so not having anything faster wasn’t an issue for me.

      4. This is a great review. I ordered this as an expansion for my two bay terramaster NAS. And it makes me feel better knowing I’m not really going to want to buy the fastest drives available since there is that bottleneck. So a budget case makes me buy budget drives. And I’m really going to be very happy with 900 mb/s read and write. I’m planning to basically make those first two drive bays mirror my NAS to give me an extra backup since my NAS is the only place all of my data is stored. Then I’ll use the m.2 nvme drives as a hot array for editing 4K video. I’m saying goodbye to working directly off my Mac! That said, I’m wondering what drives you recommend I get so I can get the max read and write this thing is capable of without spending more than is necessary? What drives will be optimal in this case to keep cost down but take advantage of the most performance? Thanks

      5. Can the 4 3.5″ drives be set up in software RAID0? If so what’s the best software to use on Windows? And can it then be connected to different computers, e.g. desktop and laptop?

        I’m asking because in my use case, it would be nice to be able to purchase 2 of these, populate with 2 x 18TB Seagate IronWolf Pro drives each, then set them up in RAID0 and cloning from one to the other as a local backup. It would work with the included hardware RAID onboard for now, but thinking of future proofing it’d be good to be able to utilise the additional 2 3.5″ inch bays to extend for future requirements to add in additional 18TB drives as required and then expand the RAID0 (even if having to reformat, as would then be able to clone everything back from the other enclosure once set up). The additional NVMe drives would then be possible expansions too, just for pure capacity if needed, rather than any RAID expectation.

      7. Love your videos for all the helpful information. I started watching your videos when I was considering the storaxa(?) NAS on Kickstarter and ended up NOT backing it thanks to the useful information shared in your videos. Also appreciated all the information regarding the recent UGreen NAS, especially the collaboration with Logan (TwoGuysTech) and others regarding the UGreen NAS.

        I have also seen your reviews about the recently announced Terramaster F4-424 Pro NAS. I understand Terramaster’s TOS lags behind the industry leaders but from your video regarding TOS 6, I understand they might be catching up.

        I wonder how well this D8 Hybrid might work with the newer Terramaster F4-424 Pro NAS with TOS 6 – especially if there might be any extra features in TOS 6 for Terramaster branded DAS such as the D8 hybrid? Similarly, wonder how the D8 Hybrid might work with other (non-Terramaster) NAS devices? Any chance you might be working on videos for either of these scenarios?

        Thanks as always and keep up the great work ????

      8. Hi. Yes interesting thing. So it is possible to setup raid in the H8 from a NAS! Is this hardware raid still from the NAS?

        Utilising the (hardware/software?) raid in the H8 in the first two bays? Also putting the other single drives in some sort of raid – would this be software raid?

        Thanks..

      10. Now that I think about it, how many NAS models manufactured by TerraMaster have Thunderbolt? Probably very few if any and if they were looking to produce a companion product to their lineup they would have to go with the ubiquitous USB.

      13. I use a similar device for Plex. I don’t need RAID for Plex since I have never had any issues with my JBOD setup. Since RAID is not a backup I just prefer to have a simple set of disks with my media files. If I lose a drive I will just re-build my library. Also this device would be nice because the NVME drives could be used for downloads and Plex cache/transcoding disks. So this could be plugged into and old Dell OptiPlex and would be a great upgrade for Plex.

      14. USB HDD/SSD boxes are ALWAYS problematic for me. I run a Mac mini as my NAS and when using USB enclosures I always have disks randomly disconnecting on me. I’ve had enough so I went Thunderbolt. 150% more expensive, 100% less headaches.

      18. Missed one use case. Data hoarders who have a bunch of old smaller hard drives and SSDs lying around that are too small to fit in current NAS.

        For $199, it means you can make use of all your old storage and also not need it on 24/7 with primary NAS.

      19. i like JBODs for the same reason i like unraid; if the pool fails and data is lost, it only loses the data on the dead drive, every other drive’s data is fully intact and retreivable. also makes it possible to use the hot swap bays as truly hot swap bays, effectively treating hard drives as massive usb keys for moving huge files around faster than any network could ever do it.

      25. I’m a photographer and have backed the Kickstarter (€199 is an excellent price to performance). My main pc is a minisforum um790 pro with 64gb of ddr5 and I have a lot of external drives attached via USB4 and USB3.2 GEN2. I intend to house 4 hdds and 2 1TB NVME drives in the DAS. I’ll keep a 1TB system drive and a 2 TB work drive (both NVME ) in my PC while attaching 2 further ‘hot’ photo drives (2 * 2TB NVME) attached to the 2 USB 4 connections. I have a docking station (USB3.2) for other peripherals.
        I think the logic is sound but if you spot any serious flaws please let me know… Oh I have a 14TB hdd attached to my router which holds backups of the important data from the other disks and additional online storage of my ‘best’ photographs. This is my hobby, not my profession

      28. Since it has a JBOD port, I’ll strongly consider getting two of them to expand a cluster of two Dell VEP4600 VM hosts – they only have two internal SSD slots (M.2/NGFF SATA). So each cluster node would be connected to one Terramaster. Cost pretty much nothing compared to the base system and you don’t _have_ to use multiple bays, you can just increment once you have a reason to. Yes, performance will be limited, but look at me caring. Not to mention that what perf you get is much more dependent on the type of SSD you get (i.e. Micron 7450 MAX instead of a Samsung Pro model – only one of those two will be performing well for small IOs. You’d pretty much need 4 top of the line enterprise M.2 SSD or Optanes to even max out the USB interface on 4k writes)
        Would be awesome if they notice the market opportunity and make one with two power supplies (i.e. an external one like on mikrotik)

      30. went with qnap tr-004 for das. no raid, no nas here, just a htpc with fractals big node that has 9 drives (10th impossible to install due to sata controller being right above the space for 10th drive). so, running the qnap in das mode, all great, drives nice and comfy and cool, software is rudimentary in das mode, but does display smart data. mind you, now i have 4 red plus drives which will be eventually replaced with 16tb red pro drives (since those are only 70$ more expensive then 12tb red plus drives – 4tb and 2yrs of warranty for 70$ is a nobrainer imo). so, those will run hotter, but i dont expect much more than these which are around 30c. true, they mostly sit idle, lol, since all my drives are just storage for htpc media. 91tb all filled in the big node. need. more. space. more. more. more! lol. cheers.

      32. I would attach it to a cheap, low power mini-PC, with one or more 2Gbps ethernet ports, share out the SSDs as NAS and then use the HDDs to take frequent backup snapshots that could be periodically swapped out for offsite storage.

      35. I’ve reconsidered my position on the Tarramaster H8 Hybrid. If the NAS OS can manage the RAID array then the lack of hardware RAID 5 is far less perplexing. They could eat Synology’s lunch when it comes to expansion units if it can function that way in DSM7. Same for QNAP, Asustore and so on.

      36. As a Qnap TR004 user i would have been keen to look at this unit if it had the hardware RAID onboard.
        The Qnap does (and is price comparable) but only 5gb/s USB and no NVME.

        My use case is as a photographer for photo storage (not generally live edited from but some decent performance to go through libraries etc is nice).

      37. Apple has had Thunderbolt 40gbit since 2016. USB and manufactures have really been hindering performance out of serious laziness for almost a decade. 10gbit should be what 5gbit USB is right now. It should be for the cheapest garbage USB sticks and cell phones. It’s just not enough people are complaining to them to be forced to want to do something. Every motherboard and computer should have at least 1 20gbit USB port and USB4 should be an almost certainty when you’re not going budget build. The fact that everything around USB has been evolving at warped speed should have pressured manufactures to implement faster ports. This has just been terrible for consumers.

      38. I think the D8 sounds very interesting, because I think RAID is a liability that I don’t want to pay extra for (I prefer no RAID at all). Instead, I just want to store most of my hot-access data to SSD’s, which have better file integrity compared to HDD as long as they are plugged it and receiving power, store some of my warm-access data to more affordable HDD, and then tell my OS to do a nightly backup of those two data pools to a third HDD data pool. I think that’s exactly what the D8 offer. I don’t need RAID, because if I run integrity check and one of the files in my hot-access or warm-access data pools got corrupted, then I can just restore them from the backup data pool. All I have to do is run an system-wide integrity check overnight once a week, and save myself the troubles with RAID.

      41. For me it was perfect and then fell with no network card. It is not a NAS in my opinion, its a glorified usb external hardrive. You can buy caddys that do the exact same job for 40 bucks. They wont run any applications, but they will use mutiple drives of different types. They blow the expansion arguement out of the water for me. Why have a processor when its running into another NAS that will more than likely do it already.

      42. Still don’t think that just short of 1gb/s systained performace is great. maybe if it had a TB4 interface you could get what little over 4gb/s. Its much like the NAS systems based on NVME drives, very few home or SOHO users a have multi 10gb LAN system to support what NVME drives is capable of. in most cases people are limited to maybe a 2.5gbit lan a spinner based system is more than good enough unless you absolutely have to be able to stream high quality 4k or 8k videos. With a TB4 connection it would be a nice little box for especially Mac users where the max is what 4tb internal SSD ?

      46. your opinion of the D8 HYBRID VERSION for a movie & tv show plex library via a mac mini? i’m currently simply using a 14tb seagate drive backed up w/carbon copy cloner on another 14tb seagate. thanks for your videos.

      48. I’m looking to expand my storage options but am far from knowledgeable on the topic. I was hoping for a more down-to-earth review. Raid I get it, but I don’t understand how the NVMe drives fit into this solution. When connected to my Mac, would I actually see two drives?

      49. Correct me if I’m wrong, but if in JBOD (or maybe I mean SINGLE) mode and using software RAID 1, the host computer has to send a copy of the data to each drive separately thus reducing the write speed (each drive can write at 1/2 the USB link speed). I recently noticed this after I played with the QNAP 4-bay DAS box TR004. Thanks for all your great videos, I have been enjoying them!

      50. I could see this being an option for offsite, archival of a more robust NAS … If I could access it as a USB attached drive from my router through OpenVPN this would be a perfect “1 copy at a different location” option for the 3:2:1 data safety plan. Since my brother is getting my current router when I upgrade to WiFi 7 with 10 Gbe next year, I could talk him into keeping a box plugged in in a nearby closet. It’s easier as I’m already the family tech support.

      52. Compared to Thunderbolt and USB4, many motherboards supporting AM4 CPUs include a USB-C 3.2 2×2 Gen 2 port at 20Gbps. – This is much more cost effective than the upgrades required for a 2x10Gb Ethernet NIC. USB dual role is supported by Windows and is widely used for file access on android phones (MTB mode). so far only JBOD drive enclosures supporting dual NVM drives at 20Gbit speed are available, running ethernet over USB is technically feasible and supported by a number of SOCs (beaglebone) in USB-OTG mode. looks like untapped potential for low cost DAS and NAS based on controllers such as ASM3242 – expect new Chinese products in this space very soon.

      54. This reminds me of a solution I used for a server a long time ago. This was back in the parallell ATA days. It was a two drives chassi that took two 5.25″ spaces in the chassis. It supported Ultra ATA 66 both for the individual drives and as the interface to the motherboard. It supported RAID 1 for the drives which made it extremely simple to use. For many years this remained our main server and every week one of the drives would be replaced and taken home by my boss. The rebuild didn’t take all that long and was done during the night. Besides the drive was swapped Friday evening and normally the company wasn’t at all active during the week end. We also had a daily tape backup done so this was second stage backup. One thing I learned early was that a tape backup was great, but just some times a restore wasn’t 100% certain to work even if it did a successful verify after the backup. Never had to use either backup before migrating to a better server.

        Something that was interesting was that the drives used in this server was the IBM Deskstar 75GXP, the so called Deathstar drives after all the problems they caused. Thing is we sold hundreds of these drives and had very few that suffered the Click Of Death that the model became known for. When I presented our data in a discussion on a website I got called a liar, a IBM shill, a troll and all kinds of things. Still didn’t change the fact that for some reason I still can’t explain. The ones in our server stayed in use for many years and only got exchanged when we needed more storage.
