Why Internal 3.5″ Hard Drives Are Still Essential

While SSDs dominate the spotlight, Internal 3.5″ Hard Drives continue to provide unmatched $/TB efficiency. They’re ideal for long-term backups, high-volume media libraries, and RAID configurations. In addition, their proven magnetic technology offers consistent speed and data reliability across years of use.

Smart Upgrade Paths

Buying Tips for Builders and Upgraders

  • Capacity: 8 TB + for NAS and media servers; 4 TB or less for daily workstations.
  • Speed: Choose 7200 RPM for faster loads; 5400 RPM for quiet, cool operation.
  • Cache & Interface: Larger caches (≥256 MB) and SATA III improve sustained throughput.
  • Reliability: Check annual failure rates at Backblaze.
  • Warranty: Look for 3–5 year coverage on enterprise or NAS-rated lines.
