What differs between these models?
- Cache (MB): ST22000NM001E lists 512; HDWG82CXZSTB lists 1024.
- Sustained transfer (up to MB/s): ST22000NM001E lists 285; HDWG82CXZSTB lists 298.
A larger cache, higher RPM or higher advertised sequential speed alone does not establish which drive is better for your workload.
