Compatibility, noise, shock and reliability
- Use a SATA host or compatible bridge; a 1.5 Gb/s device can generally negotiate on later SATA hosts, but BIOS limits, bridge firmware and power behavior can still prevent use.
- Momentus 5400.2 family documents specify noise levels by idle/seek mode and shock limits by operating state. Treat the stated non-operating shock rating as a controlled test condition, never as a drop allowance.
- Load/unload and reliability ratings are population-level design limits, not a warranty or estimate of the remaining life of a used unit. Back up verified data independently.
- Check logical sector reporting and actual addressable capacity before imaging, partitioning or using a legacy operating system.
