Exact product identity & open questions
- Manufacturer part number
- HAT3300-4T[1]
- Product
- One 4TB internal 3.5-inch SATA HDD from the Synology Plus Series family; enclosure and additional drives sold separately.[1]
- Revision rule
- Match the complete HAT3300-4T suffix on the listing and delivered label; another 4TB family member is not interchangeable evidence.[1]
- Printed factory model on Hardwareluxx samples
- ST4000VN3300 (Seagate-style identifier on two Synology-labeled HAT3300-4T samples)[3]
- Long-term reliability: No controlled exact-MPN field failure-rate or service-life study is adopted. Workload, MTBF/MTTF and warranty ratings do not predict the life of the delivered unit.
- Host compatibility: The target NAS model, bay position, firmware and capacity ceiling were not specified. Family NAS positioning does not establish arbitrary host compatibility.
- Unpublished exact-model specifications: The adopted official source does not state: Unrecoverable read error rating, Load/unload cycle rating, Startup current, Standby / sleep power. These fields remain Unknown rather than being copied from another MPN.
- Current US offer coverage: No qualified current US offer for exact HAT3300-4T. Newegg 2026-09-11 H1 HAT3310-4T vs Model HAT3300-4T is an identity conflict. B&H $229.99 is historical 2026-08-30. Amazon price still unknown.
- Newegg selected identity: HAT3300-4T versus HAT3310-4T on the same Newegg PDP (H1 vs spec Model vs ItemDetail Title). Cannot call the selected item exact. Pending live confirmation of the chosen variant.
