CMR or SMR? What we can and cannot source for this part number
Part of the Seagate line we track.
The Seagate IronWolf Pro 20TB NAS is a 20TB SATA-6G enterprise drive - Verify recording technology before use in RAID. New unit with full 5-year warranty.
Recording technology: Seagate documents CMR for the IronWolf Pro family; this part number is not named individually. A family can ship more than one recording method, so treat this as the family's answer rather than a verified answer for this drive.
We do not have enough in-stock comparators of this type today to place this price against the rest of the market. The category page below ranks everything we do have.
These are third-party figures about the retail market as a whole, quoted and dated. They are not our own measurements and they do not describe this specific drive.
Resolved against manufacturer compatibility lists we read and dated, capped at 4. Vendor-listed means the manufacturer names this exact part number; fit-verified is our own check of form factor, interface and recording technology against a published requirement. Neither is a guess, and a drive the registry cannot resolve shows nothing here rather than a maybe. How compatibility actually works
