Home & SOHO Storage Synology Plus Series: Essential Reliability for 24/7 Systems The Synology Plus Series HAT3300 (4TB & 6TB) provides the perfect balance of quiet operation and rugged reliability. Purpose-built for small office and home NAS environments, these drives utilize Conventional Magnetic Recording (CMR) technology. This ensures superior data integrity and faster RAID rebuilds compared to standard desktop SMR drives, making them the gold standard for entry-level professional storage. Technology 5400 RPM CMR Reliability 1.0M Hrs MTBF 4TB vs 6TB: Capacity Comparison The HAT3300 series is optimized for low power consumption and reduced noise, ideal for desktop NAS units kept in living areas or quiet office spaces. Specification HAT3300-4T HAT3300-6T Capacity 4 TB 6 TB Sustained Data Transfer 202 MB/s 202 MB/s Rotational Speed 5,400 RPM 5,400 RPM Cache (Buffer Size) 256 MB 256 MB Recording Tech CMR CMR Workload Rating 180 TB / Year 180 TB / Year Interface SATA 6 Gb/s SATA 6 Gb/s Why Choose Synology Plus Series? DSM Integration Enjoy automatic firmware updates and health monitoring directly through Synology DiskStation Manager (DSM), keeping your data protected without manual effort. Quiet & Cool Operation The 5400 RPM motor is specifically designed to minimize vibration and heat, extending the life of your NAS hardware and reducing environmental noise. Tested for Compatibility Over 300,000 hours of rigorous testing ensures these drives handle multi-user workloads and demanding 24/7 uptime requirements. Reliable RAID Performance Tuned to prevent drive drop-outs, the Plus series offers significantly more stability in RAID configurations than standard "Blue" or desktop-class drives. Frequently Asked Questions Will this work in Hikvision, Dahua, or UniFi Protect? Yes. The HAT3300 is a standard 3.5" SATA drive. It is fully compatible with Hikvision NVRs, Dahua NVRs, and Ubiquiti UniFi (Dream Machine Pro, UNVR) systems as a reliable, cool-running storage option. Is 5400 RPM fast enough for 4K video? Absolutely. For NAS and NVR storage, data density is more important than raw RPM. These drives easily handle multiple 4K video streams simultaneously while staying cooler than 7200 RPM models. How does the firmware update work? Unlike other brands, Synology Plus drives allow you to update firmware directly through DiskStation Manager (DSM). This ensures your drives stay compatible with the latest OS features without data risk. What is the warranty period? These drives come with a 3-year limited warranty, fully supported by our Australian technical team at CCTV Guru, providing peace of mind for your 24/7 surveillance or data storage.

Enterprise-Grade Storage Synology Plus Series: The New Standard in NAS Reliability The Synology Plus Series HAT3320 is purpose-built to bridge the gap between entry-level storage and enterprise performance. Designed for 24/7 reliability in Synology environments, these drives utilize Conventional Magnetic Recording (CMR) to ensure your data remains accessible and safe during heavy multi-user workloads. With a fast 7,200 RPM spin speed, they deliver the high-speed throughput required for modern data-intensive applications. Technology 7200 RPM CMR Reliability 1.2M Hrs MTBF 8TB vs 20TB: Capacity Comparison Choose the capacity that fits your growth. While both models share the same rugged reliability, the 20TB model offers higher data density and faster sustained transfer speeds. Specification HAT3320-8T HAT3320-20T Capacity 8 TB 20 TB Sustained Data Transfer 281 MB/s 295 MB/s Cache (Buffer Size) 256 MB 512 MB Recording Tech CMR CMR Idle Power Consumption 5.74 W 4.35 W Weight 720 g 670 g Optimized for the Surveillance & NAS Ecosystem Seamless Firmware Updates Keep your drives at peak performance without technical hurdles. Firmware updates are delivered directly via Synology DSM, ensuring zero-hassle maintenance. 27% Faster RAID Repair System-level integration allows these drives to rebuild RAID arrays significantly faster than generic third-party drives, minimizing your downtime. Multi-Platform Compatibility While optimized for Synology, these drives are a high-performance alternative for Hikvision, Dahua, and UniFi Protect NVRs and video recorders. Small Office Optimized Ideal for multi-user environments (SOHO), providing consistent performance even when multiple users are accessing the NAS simultaneously. Frequently Asked Questions Will this work in Hikvision, Dahua, or UniFi Protect? Yes. The HAT3320 is a standard 3.5" SATA drive and is fully compatible with Hikvision NVRs, Dahua NVRs, and Ubiquiti UniFi (Dream Machine Pro, UNVR). It is an excellent high-performance upgrade over standard surveillance drives. What is the benefit of CMR over SMR? CMR (Conventional Magnetic Recording) allows for faster, more consistent write speeds during large data transfers or RAID rebuilds, which is critical for NAS and NVR health and longevity. Is the 20TB model louder than the 8TB? Actually, the 20TB model uses advanced helium-sealed technology, which results in lower friction, lower power consumption, and often quieter operation compared to traditional air-filled drives. Does this include a 3-Year Warranty? Yes. Every Synology Plus Series drive is backed by a 3-year limited warranty, supported locally by CCTV Guru's Australian technical team.
