What wholesale buyers check before ordering drives
- Exact part number — capacity alone is not enough; interface, sector format and firmware family matter for mixing into an existing array.
- Enterprise duty class — Ultrastar-class drives are rated for 24/7 operation; desktop drives are not a substitute in arrays.
- Testing before shipment — functional verification on the seller's own bench, with records on request.
- Written warranty — ours: a 90-day warranty from delivery on every unit.
- Export documents — commercial invoice, packing list and HS code issued with the shipment.
