New vs Recertified vs Refurbished

Every part is sold by exact manufacturer part number and ships warranty-backed. Here's what each condition means so you can weigh price against your workload.

New: Factory-sealed and unused, with the full manufacturer warranty. The safest choice for a fresh build or a warranty-sensitive deployment.
Recertified: OEM-recertified and restored to original specification, typically with low power-on hours. Health-tested and backed by our own replacement warranty — the same usable capacity for a lower price.
Refurbished: Professionally tested working pulls, wiped and inspected. A cost-effective option for labs, cold storage and non-critical tiers, warranty-backed.
