NAS hardware tools
Check the parts on a shortlist and explore the hardware budget before ordering. These tools run in your browser without signup. Each explains what its results cover and where to verify the underlying specifications.
CMR/SMR Drive Model Lookup
Enter a drive model number to check its published recording technology. Every listed WD or Seagate disk links to the manufacturer's disclosure table, with the document date or revision visible. The index also includes selected NAS enclosure specifications. Partial matches stay provisional, and missing models stay unknown, so you can distinguish a documented result from a similar name on a retailer's listing.
NAS Drive Bay and PSU Calculator
Enter a capacity target after parity, choose a drive size and compare a one- or two-parity-drive layout. The calculator estimates chassis bays, example expansion-card lane requirements and startup power under its stated assumptions. Leave a separate allowance for filesystem overhead and free space. Verify the electrical slot widths, drive startup current and PSU rail limits against the actual component manuals before purchasing.
Use the guides alongside the tools
The NAS buying guide owns the complete build decision, including chassis backplanes, HBAs, ECC memory and cooling. Read CMR or SMR for NAS arrays to interpret a drive lookup, or follow the NAS hardware transfer diagnosis if an existing machine is slower than expected.
