IDE / PATA 3.5 inch Hard Drives

This is the classic desktop drive: 3.5 inch, 40-pin parallel ATA, jumpered master or slave. It is also the part most often needed to revive an industrial controller, a vintage PC or Mac, an arcade board, or a piece of lab equipment whose manufacturer stopped supporting it years ago.

  • Standard 40-pin IDE connector with Molex power
  • ATA-33 through ATA-133 interface generations
  • 5400 and 7200 RPM spindles
  • Capacities from sub-gigabyte vintage units through 500 GB
  • Western Digital, Seagate, Maxtor, Quantum, Conner, Hitachi/IBM Deskstar, Fujitsu

Older BIOS revisions cap the addressable capacity, so on very old systems a smaller drive is often the correct choice rather than the largest one available.

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.
