After a few weeks of running my new NAS box (a Lenovo Tiny m720q with a USB attached terramaster D4-320 that houses 4 spinning drives, 2x4TB in RAID1 and 2x8TB in RAID1) and a lot of people warning me that RAID and USB connected drives is a recipe for disaster, I can safely say that it JustWorksâ„¢ for me. Sure, it isn't NVME style super fast, but it happily deals with backups and file copy over the gigabit network I have at home with full saturation of said network connection. Works for me :)
@jwildeboer I use two RAID1 USB Boxes at home for backups of my proxmox VMs. Never had an issue in > 2 years so far. But I was sceptical as I had connection issues in the past with USB attached disks. But maybe that's the thing: issues of the past 🙂
