Warranty provider
A manufacturer's specification describes an eligible new drive. OEM, bulk and renewed offers may have different seller or manufacturer coverage.
Workload and compatibility
Confirm SATA versus SAS, drive dimensions, supported bays and the model-specific workload rating before buying.
Usable capacity
Account for formatting, redundancy and free space. A mirror uses two drives to provide approximately one drive's capacity; it does not replace an independent backup.
Frequently Asked Questions
Which hard drive has the lowest price per TB?
The first row has the lowest price per TB among the matching, recently checked listings we track. Filter by condition and interface before comparing; the lowest capacity cost is not a reliability rating.
Does a new hard drive remove the need for backups?
No. Either a new or used drive can fail. Redundancy can maintain service after some drive failures, but it does not replace an independent backup.
Can I use any large HDD in a NAS?
Confirm the exact model against the enclosure's compatibility list, recording technology, interface and workload requirements. Capacity alone is not enough.
