Compatibility, noise, shock and reliability
- Use a SATA host; allow 9.5 mm clearance and confirm controller/BIOS support for the capacity and 512e logical sector presentation. An interface match alone is not a boot or RAID compatibility guarantee.
- The manufacturer data sheet and installation guide specify noise, operating/non-operating shock and acoustic test conditions. Keep the drive protected from shock and vibration; those lab limits are not handling targets.
- Check exact suffix before relying on SED, enhanced-availability or other family options. Published reliability ratings are population/design values and do not certify this drive's current condition.
- When preserving data, avoid filesystem repair or write tests; record firmware and host details and make a verified image before analysis where safe.
