β οΈ IMPORTANT β PLEASE READ BEFORE PURCHASING β οΈ
These are Enterprise SAS (Serial Attached SCSI) hard drives β NOT SATA drives.
Although they may appear similar, SAS drives use a different interface and are not compatible with standard desktop PCs, consumer NAS devices, or systems with SATA-only controllers.
Please ensure your server, RAID controller, or HBA supports SAS drives before purchasing. Returns due to compatibility issues will be declined.
π Product Overview π
The Dell / HGST Ultrastar He12 12TB Enterprise SAS HDD is a high-capacity, enterprise-grade hard drive engineered for demanding 24Γ7 server, storage array and data-centre environments.
Manufactured by HGST (Western Digital) and supplied as a Dell Enterprise Class drive, the HUH721212AL5200 combines a high-speed 12Gb/s SAS interface, 7,200 RPM spindle speed, 256MB cache and enterprise-class CMR recording technology, delivering sustained sequential transfer rates of up to approximately 255MB/s.
Built on HGST's proven HelioSeal helium-filled platform, the Ultrastar He12 was designed specifically for high-density enterprise storage. The helium-sealed design reduces internal aerodynamic drag and enables high capacity while maintaining excellent power efficiency, thermal characteristics and long-term reliability.
Reliability is a major advantage of the Ultrastar enterprise platform. These drives are designed for continuous 24Γ7 operation and carry a manufacturer-specified reliability rating of 2.5 million hours MTBF, making them substantially different from ordinary consumer or desktop-class hard drives.

π Return Policy β Read Before Requesting a Return π
1. Pre-Shipment Quality Assurance:
Any disks sold undergo a strict, documented preparation process:
- Secure Wipe: Each disk is securely wiped, 7 passes, prior to being sent.
- SMART Verification: A SmartCTL comparison is done both BEFORE and AFTER the 7-pass secure wipe to ensure disk integrity. Any disks that demonstrate error degradation are disposed. This is far more reliable then a simple SMART report.
- Operational Confirmation: Only disks that pass all health checks and are confirmed to be in proper working order are shipped.
In short: drives do not leave our possession in a faulty state. Every unit is verified and documented before being shipped.
2. Packaging Standards:
Hard drives are sensitive electronic components. We treat them accordingly.
- Disks are packaged with anti-static protection.
- Multiple layers of protective bubble wrap and/or protective packaging are used.
- Internal movement is eliminated to prevent shock damage.
- Outer packaging is reinforced to minimise transit-related risk.
9We package with the utmost care to ensure disks do not arrive damaged. If a drive arrives damaged, we expect clear evidence of shipping damage, rather than vague claims.
3. Returns β Conditions and Procedures:
VERY IMPORTANT! PLEASE READ!
If you wish to return a purchase, the following terms apply:
- Return postage is paid by the buyer.
- For partial refunds the Ebay selling transaction fees are not refundable and still charged by Ebay. These will be paid by the buyer and deducted from the buyer's refund.
- Because hard drives are sensitive devices, and because improper installation, static discharge, impact, or mishandling can cause damage, all returned disks will undergo full diagnostic testing upon receipt. The administration costs of diagnostic testing will be paid by the buyer (see below - Section 4: Returned Hard Drive Diagnostic Fee).
Returned drives will be:
- Re-tested using SMART diagnostics
- Scanned for new bad sectors
- Evaluated for excessive power-on hours
- Inspected for physical damage, tampering, or serial discrepancies
We will verify the driveβs integrity and determine whether it is fit for resale.
If the disk shows:
- Evidence of misuse
- Physical damage
- Serial number mismatch
- Data alteration inconsistent with normal use
- Signs of attempted part-swapping or component harvesting
β¦ the return will be rejected.
4. Returned Hard Drive Diagnostic Fee:
Facilitating a hard disk return is not a simple matter of putting a disk back on a shelf. Nor can any internal damage that may have been incurred after the buyer received the disks be immediately visible when looking at the disk.
Each returned drive must be:
- Re-tested
- Re-wiped
- Re-documented
- Re-packaged
This process takes time and incurs cost. For this reason, all approved returns are subject to a 30% restocking fee.
This fee reflects:
- Shipping logistics and collection
- Diagnostic labour
- Administrative processing
- Depreciation from opened/used status
- Risk exposure associated with reintroducing electronic storage media into inventory
5. Final Note:
We operate transparently and professionally. False return claims, misuse disguised as defect, or attempts to exploit policy will be identified through testing.
If you are uncertain about compatibility or specifications, ask before purchasing. We are happy to provide technical clarification. What we are not happy to do is subsidise careless handling or fabricated faults.
Purchase responsibly. Handle hardware correctly. Read before requesting a return.
