Compatibility and buying checks
- One or both drives use SMR recording. Check sustained-write and array requirements before choosing one for a NAS or a write-heavy workload.
- Compare new and renewed offers separately. The manufacturer specification does not guarantee the warranty or return policy of a marketplace seller.
