20TB+ Hard Drives
This page lists hard drives of 20TB and up, the largest capacities in current enterprise lines. That includes newer Seagate Exos and WD Ultrastar generations, in SAS and SATA versions. They suit builds where bay count, power or rack space is the limit: large ZFS pools, backup and archive targets, and media servers. The trade-off is rebuild time. Resilvering a drive this size takes a long time, so most builders use double parity such as RAID 6 or RAIDZ2 and keep a spare on hand. Some of the largest models also use newer recording methods, so confirm the model number against your NAS maker’s compatibility list before you buy. Check the interface and sector format against your controller, and compare the power-on hours we list for each unit. Every used drive here passes SMART health and an extended self-test before it ships.

20TB+ Hard Drives: common questions
Will my NAS recognise a 20TB or larger drive?+
Current NAS operating systems and HBAs address these sizes without trouble. Older NAS models and some USB docks can have a size limit, so check the maker’s compatibility list for your unit.
How do I know how many hours a drive has?+
We read power-on hours from the drive’s own SMART counter. On certified listings they are printed on the certificate in the box and shown on the unit’s public test report. The counter stays on the drive, so you can read it yourself on arrival with any SMART tool.
What warranty comes with these drives?+
Used drives carry a 90-day warranty, and certified tiers carry up to 2 years; the exact term is on each listing. New sealed drives keep the manufacturer warranty. Every order also has 30-day returns.
