TerraMaster D8 Hybrid DAS - 4 Bay SATA + 4 NVMe - How good is it?

I review the upcoming TerraMaster D8 Hybrid DAS. How does it stack up and what other options does it compete with? I look at the hardware, its RAID abilities and test the unit for performance against its USB 3.2 Gen 1x2 / USB 3.1 Gen 2 10Gbps spec.

Great review! If I didn’t already have my storage needs sorted out. I would definitely be looking at one of these.

13:07 - also, market research. Interest in Kickstarted may be a good indicator of market demand which will help even an established company to optimise their production, supply chain, and logistics.

It would be good to see if/how this performs with 4 x 3.5” drives AS single disks and then set up in software RAID5. I have a home music studio and looking for a DAS for local cold storage, with the hot storage being NVMe and SAsAd internally within my desktop. Being a DAS (rather than a NAS) then also allows for a Backblaze cloud backup for cheap of everything too. This looks good for my niche use case, just wish it had RAID5 across all 4 hard drives.

This looks pretty interesting for attaching to my Odroid C4 Openmediavault NAS.

Great review.
Pretty interesting, but Im going to wait until its fully released to see if any issues start occuring after the official launch.

Im one of those people who would only use JBOD in such things.

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

your opinion of this for a movie & tv show plex server 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.

[BuzzJones]

Im not sure if I should get the OWC Thunderbay Enclosure with Thunderbolt 4 or this one with the slower USB 3.2 Gen 2 connection ?
What would you say is better for Video editing off of with my M4 MAX Macbook Pro I just got ?

Hello, thanks for the good review video. I took delivery of this about 2 weeks ago and have populated it with four 12TB Seagate Exos HDDs only. I'm using it with an old Mac mini (2014) and have managed to do a nested RAID (not sure what the proper term is) where bays 1&2, and bays 3&4, are in individual RAID 0s; the two RAID 0s were then put in RAID 1, and it seems to be working well. The funny thing though is that the DAS is showing up in the System Information as a "4-port USB 2.0 hub" and the write speed seems to average out around just under 40 MB/s. Does this all sound right?

The Realtek RTL9210 chips are PCIe 3.0 x2 to USB 3.2 Gen 2 bridge chips, FYI. The RTS5432 is a USB 3.2 Gen 2 hub.

[Harrysound]

First off, excellent video, very well done. Personally I really fancy 2 drives in raid and then 1 or 2 sata drives for random nonsense and then maybe the m.2 drives for audio sample libraries or something like that…. I just don’t really like the price. £300 seems a little steep so maybe I’ll take a look at the 2 bay and the Qnap you mentioned in this video.

[killacam]

New to Home Storage. Would I have any issues using this as a Media server as well?

[-iIIiiiiiIiiiiIIIiiIi-]

You can still use this much cheaper DAS for Software RAID. I'm more interested in the redundancy over performance anyways.

[sevenismy]

Maybe use it in single mode and then put a software raid on it.

[jack]

Couldn't you just get a tower case and shove some extra drives in it? Seems a bit niche.

[berkertaskiran]

Raid for SSDs is more than just speed. Another product that shows why someone should avoid those NAS/DAS boxes...
