Deal Details

I came across a pretty solid deal on the TERRAMASTER D4-320 4-Bay USB-C Direct Attached Storage (DAS) enclosure.

This is not a NAS, so it connects directly to your computer over USB-C. If you're looking for a simple way to expand storage for media, backups, Plex libraries, or photo/video editing without dealing with networking, this is worth considering.

Highlights
4-bay enclosure (diskless)
USB 3.2 Gen2 (10Gbps)
Up to 120TB total capacity (4 × 30TB drives)
Supports both 3.5" and 2.5" SATA HDDs/SSDs
Hot-swappable drive bays
Tool-free drive installation
Compatible with Windows, macOS, and Linux
Works with Thunderbolt 3/4 ports via USB-C

A few things I like:

Each drive shows up individually (no forced RAID).
Easy to swap drives without opening the enclosure.
Quiet cooling fan with decent airflow.
Good option if you already have spare SATA drives lying around.

Keep in mind this is a DAS (Direct Attached Storage), not a NAS. There are no built-in RAID features, so if you're looking for network sharing or hardware RAID, you'll want a different model.

Overall, it seems like a nice solution for:

Home backups
Media collections
Plex/Jellyfin storage
Photo & video editing
Extra storage for desktops or laptops

This is so awesome. It will only cost $3200 to put in hard drives. Yay AI data centers.

Seriously! NAS, DAS and hard drive enclosures should all be at an all time low right now since HDD prices are so high!

Anyone have experience with using one of these, or some of the similar Terramaster units, with UNRAID?

Look at you and your fancy SATA drives. I'm still rocking IDE drives.

Unless things have changed, Unraid does not like USB drives, from a parity perspective. MergerFS and Snapraid on straight linux or OpenMediaVault would work well with a USB DAS enclosure.

I had issues using this with my beelink n100 mini pc and OpenMediaVault. Connection kept dropping and I couldn't even format drives. I had to default back to the old usb-storage driver instead of UAS and plug it into a usb 3.0 unpowered hub for it to play nice. Seems like this may be a Linux kernel 7 issue and if you're running an older kernel, you may not need to do the same workarounds. Doesn't seem to be the DAS's fault though as external usb drives behaved the same way.
