4TB Enterprise Hard Drives

Shop 4tb hard drives at US IT Hardware — every hard drive sold by exact manufacturer part number, so it seats in your server or array and is recognized on the first boot. We stock New, Refurbished and Recertified units from HPE, Dell, Seagate, Western Digital, Samsung, Micron and more — filter by the specs that matter or search the exact part number. These are enterprise/nearline hard drives built for 24/7 duty, with the workload ratings and error-recovery firmware desktop drives lack. Compare the real price-per-terabyte across New and Recertified stock in the listings below before you buy. Every hard drive is health-tested and warranty-backed, ships fast from the US, and purchase orders are welcome — use the bulk-quote link on any product for volume pricing or a compatibility check.

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.

Not sure which to pick? Read our New vs Recertified vs Refurbished guide.

Frequently asked questions

What's the difference between New, Recertified and Refurbished hard drives?+

New is factory-sealed with the full manufacturer warranty. Recertified is OEM-restored to specification with low power-on hours and our own warranty — the same capacity for a lower price. Refurbished is a tested, wiped working pull. All are sold by exact part number and warranty-backed.

Are these drives rated for 24/7 server use?+

Yes — these are enterprise/nearline hard drives built for continuous duty, with the workload ratings and error-recovery firmware desktop drives lack. Each product's spec table lists RPM and workload rating.

Do you accept purchase orders and volume pricing?+

Yes — we ship fast from the US and welcome POs. For quantity or a matched set, use the bulk-quote link on any product for pricing and a compatibility check.
