How we filter
Every feed has its own filter, tuned by hand for this one part. Before any change goes live, those filters are tested against thousands of real eBay listing titles. Every night, each feed is checked against every other deal page in its category, so a listing for a different part that slips in gets flagged and fixed instead of quietly shown.
Of the 37 listings we observed for this game in the last 30 days, we filtered out 8 of 37 (~22%) for quality reasons. The remaining 29 are what we'd actually surface.
- 3 shipped from a region we exclude
- 3 caught by a junk-listing guard
- 1 seller had too few feedback ratings
- 1 seller positive-feedback percentage too low
What the feed excludes
An eBay search for Seagate Exos 20TB returns far more than the part itself: laptop chips, mining rigs, coolers, empty boxes and whole PCs all mention it in their titles. These are the 42 terms we filter out to keep this feed to the real thing. A listing whose title contains any of them never reaches the feed, the price table or an alert. Many look unrelated to Seagate Exos 20TB because they are: that's the noise.

Exos 20TB: buyer & reseller spec sheet
Exact SKU identity. "Exos 20TB" covers several generations (X20, X22, X24) and several part numbers. The model number on the drive label, such as ST20000NM007D, pins down the exact drive, so match it against the seller's photo of the label instead of trusting the title alone.
Variants & value impact. The interface matters more than the asking price. Many 20TB Exos drives are SAS, which needs an HBA or a SAS-capable backplane and will not work on a standard SATA motherboard port. The same capacity is also sold as SATA. Confirm which one you are buying before comparing asking prices. Dell, HP and other OEM-labelled units belong to the same family but can carry vendor firmware.
Listing traps. The Exos X20z is a host-managed shingled (SMR) model. It needs operating-system and file-system support, and is a poor fit for a general NAS or desktop. The feed filters out titles naming it, but check the label if a title only gives a capacity. Also watch for titles that call a drive "compatible" with a Seagate part number rather than being one.
Buying a used SSD: what to check
These checks apply to every drive on our storage pages. The item notes above cover what is specific to this drive.
Used
- Ask for a screenshot of the drive's health readout (SMART data): health percentage, total data written and power-on hours.
- Confirm the reported capacity matches the label. Fake high-capacity drives exist.
- Ask whether it was wiped. You should wipe it again yourself either way.
Refurbished
- Find out the warranty and whether the health readout was reset or replaced.
New
- Check the box is sealed and register the serial for warranty as soon as it arrives.
