16TB Server Hard Drives

Key takeaways

  • 456 listings match this collection right now.
  • RAID rebuild time scales with capacity, and at 16TB a single-parity rebuild window runs long enough that dual-parity RAID or erasure coding is the safer design choice.
  • This capacity is a 7,200 RPM nearline-class drive built for density, not a 10K or 15K performance part, since spindle speeds that high do not scale to helium-class platter counts.
  • Sector format and hot-swap tray generation both have to match the target system at 16TB; getting the capacity and interface right does not mean either one fits.

16TB drives are 3.5-inch helium capacity drives in 12Gb/s SAS and 6Gb/s SATA, the common capacity point for current dense storage servers. Sector format and tray generation have to match the system.

How to choose server hard drives

Match the interface and link rate the controller or backplane presents, the bay width (2.5-inch or 3.5-inch), and the rotational class already in the array: 10K and 15K drives for latency-sensitive duty, 7200 RPM nearline drives for capacity. Replacing an array member also means matching capacity and sector format, or the controller can reject the drive.
