TerraMaster D9-320 - USB 3.2 Gen2 SATA 3.5"/2.5"

desertcart.com: TERRAMASTER D9-320 Hard Drive Enclosure - 9Bay USB 3.2 Gen2 10Gbps Type-C External HDD Storage Independent Power Control for Each Bay Hot Swappable Plug and Play (Diskless) : Electronics Review: Excellent and worth the extra coins over the competition. Self-hosting game changer for me. - Better than others by far. This is about the fourth or fifth one of these enclosure things I've bought and this one is the best by far. Build quality is excellent and made of thick plastic (quieter than aluminum). Stay away from the Mediasonic brand ones if you are using it for a server - I've gifted away two of those because the power button always had to be pressed after power loss and the usb controller was shared by all the drives (it also was weird with device naming). I'm using the TerraMaster with a Raspberry Pi 5 8GB running OMV 8, with one 8TB CMR hdd and two 6TB SMR hdd. It has a USB controller for each disk slot and I was pulling full read write speeds from the disks simultaneously. I also didn't have any disk sleeping issues (after disabling SMART monitoring and using HD-idle instead of OMV's built-in stuff). The power button is last state; it powers back ON after power loss if it was ON before the power loss. I found the trays easy to install my disks into and the latching click is very satisfying. The fan is quiet enough for my application. I used it in Unraid as well for some testing and everything looked fine on that too - including the device naming. I was copying over 400MB/s to it using a btrfs raid0 array of SMR disks over plain old usb 3.0. Review: Incredible alternative to NAS and super easy to use - Wow, what an incredible alternative to expensive NAS setups. This thing is incredible. Speeds are great and it’s awesome that you can swap out drives in seconds with no hardware. It’s super easy, works great, and the indicator lights on the front are helpful. Stays pretty cool as well. I could see this being very useful for people who need a lot of storage, especially video editors. Honestly might hook it up to my router for cloud storage if I feel like a NAS is necessary without having to buy something more expensive. Save your money, buy this and spend it on hard drives.
