Its very hard to beat Dell Wyse 3030 LT with USB attached disks.

I use that and the costs are about $20-25 for a used Dell Wyse 3030 and $60 for used 5TB 2.5 HDD from Seagate in USB 3.0 case.
Then the power bills will also be tiny as it draw about 3.8W when idle and 10.3 W with CPU and disks stressed to maximum.
The only limitation is 'only' 2GB RAM - but with ZFS ARC set to 32MB minimum and 64MB maximum RAM is not an issue.
% grep arc /etc/sysctl.conf
vfs.zfs.arc.min=33554432
vfs.zfs.arc.max=67108864
Regards.

- metadat 2y agoThat's interesting, it appears I may have been slightly mistaken. As per https://www.smartmontools.org/wiki/USB https://www.smartmontools.org/wiki/USB: > To access SMART functionality, smartmontools must be able to send native ATA or NVMe commands directly to the drive. For USB devices, at least the following conditions must be met: > The USB bridge provides an ATA or NVMe pass-through command. > This command is supported by smartmontools. > The operating system provides a SCSI pass-through I/O-control which works through its USB-layer. > SCSI support is implemented in the operating system interface of smartmontools. So in some cases, it may work depending on the USB chipset capabilities. I haven't gotten it to work on my old supermicro.. yet :) Cheers.
