Synology 4TB 3.5-Inch Plus Series SATA Enterprise HDD (HAT3300-4T)
24/7 Reliable Storage Purpose-Built for Synology Ecosystems
The Synology Plus Series HAT3300-4T 4TB Hard Drive is meticulously engineered to provide stable, continuous network storage performance for home setups, creative studios, and small business NAS configurations. Extensively validated with up to 300,000 hours of cross-platform testing inside Synology enclosures, this 3.5" SATA III drive eliminates compatibility guesswork. Utilizing 100% Conventional Magnetic Recording (CMR) technology, the HAT3300 series guarantees sustained writing speeds and dependable multi-user data protection around the clock.
Key Product Features
- Engineered for Constant Workloads: Features a Mean Time to Failure (MTTF) rating of 1.0 million hours and a 180 TB/year workload rating, delivering up to three times the longevity of basic desktop drives.
- Frictionless DSM Firmware Updates: Skip third-party diagnostic software and manual drive pulling; run automated updates safely and directly via Synology Storage Manager in DiskStation Manager (DSM).
- 100% CMR Recording Technology: Employs Conventional Magnetic Recording to ensure seamless data placement, optimal multi-user RAID rebuilding, and persistent read/write health over SMR alternatives.
- Power-Efficient & Low Vibration: The 5400 RPM rotation spindle profile minimizes heat buildup, drops acoustic noise profiles to 23-27 dB, and cuts overall operational power usage.
- Ecosystem Optimization: Tailored integration ensures faster RAID arrays and up to 27% speedier storage recovery repairs compared to standard non-certified hard drives.
