3.5 inch Hard Drives

The 3.5 inch form factor is the workhorse of the catalog and the largest single group we stock. It spans four decades of interfaces, from 40-pin IDE and 68-pin SCSI through modern SATA 6 Gb/s and 12 Gb/s SAS, which is why we break it down further by interface and by intended use.

  • SATA, IDE/PATA, SCSI, SAS and Fibre Channel interfaces
  • Desktop, NAS, surveillance, enterprise nearline and 15K enterprise models
  • Capacities from vintage sub-gigabyte drives through 24 TB
  • Western Digital, Seagate, Toshiba, Hitachi/HGST, IBM, Maxtor, Quantum, Conner, Fujitsu, Samsung
  • Both current-production parts and long-discontinued replacements

If you know the interface you need, the interface-specific pages will narrow this down faster than paging through the full list.

Every drive is tested and backed by our standard return policy. Items marked as ships in ~5 business days are sourced to order from our distribution partners and carry the full manufacturer warranty.
