In this video I picked up a pair of 18TB “white label” SAS drives from Digital Spaceport (about $209 each) and dug into the obvious questions: what are these things, why are they so cheap, and should you trust them with anything you care about. Based on what I saw and what Jared shared, the idea is these drives come from large lots that get rejected/returned for reasons that can be cosmetic, firmware-related, or worse—so they can’t be sold as new. The interesting part is they sure look like Seagate Exos X18s on the outside, but the branding/model reporting isn’t what you’d expect. Then I walk through how I provision new drives in my Chia rig: install one drive at a time so I can map it to the right slot using timestamps, check SMART attributes (power-on hours, manufacture week, defects), then partition with GPT, format ext4, remove the default 5% reserve, and label everything cleanly. I mount by UUID because with this many disks you can’t rely on /dev/sdX naming. Finally, I do the math—price per TB and power cost over time—and the takeaway is simple: bigger drives can look expensive up front, but they crush small drives on watts-per-terabyte, and that gap gets wild as electricity prices climb (especially at larger scales like 100TB to 1PB).
