      1. I have 2 Samsung 990 Pro m.2 nvme drives. Would it be a problem with them in Raid 1 ? Right now on usb 3.2 Gen 2 I am getting about 660 MB/s which is fine. I just want a backup solution.

      2. Thanks for this review. I’ve actually just taken delivery of the D8 Hybrid and was wondering if I can use a USB-C to ethernet adapter to connect it to Mac mini via ethernet instead of USB.

      3. im torn to either getting this or actual nas. i want to have storage so all my device can access the data for mp3s and movies. i want to be able to stream movies on my tv. just a simple hd files, not even 4k. therefore im not sure to get DAS or NAS for my situation. residential setup so all are gigabit / wifi6 network. can anybody help me on this, please?

      4. 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.

      5. 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.

      6. 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?
        REPLY ON YOUTUBE

      7. 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!

      8. 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.

      9. 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.

      10. 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.
