HAT3300-4T

The HAT3300‑4T is part of Synology’s Plus Series of HDDs (“HAT3300” line). It’s built for use in Synology NAS systems (home, small business, small‑/medium‑office). It is a 3.5‑inch SATA drive, optimized for 24/7 operation, multi‑user workloads, and integration with Synology’s DiskStation Manager (DSM) firmware updates.

Key Features

1. Capacity & Form Factor

   • 4 TB storage.

   • 3.5‑inch SATA drive.

2. Interface & Speed

   • SATA III (6 Gb/s) interface.

   • Rotational speed of ~5,400 RPM.

   • Sustained read/write speed up to ~202 MB/s.

3. Reliability / NAS‑oriented design

   • Conventional Magnetic Recording (CMR) technology; this helps ensure more predictable write performance (good for RAID, NAS use).

   • Designed for 24/7 operation in multi‑user environments.

   • High workload rating: 180 TB/year.

   • MTBF (Mean Time Between Failures): about 1,000,000 hours.

4. Low Power Consumption / Efficiency

   • Idle power draw: ~ 3.96 W.

   • Active/read‑write ~ 4.85 W.

5. Durability & Environmental Specs

   • Operating temperature: 0‑65 °C

   • Non‑operating/storage temperature: ‑40 to 70 °C

   • Shock, vibration tolerances (for both operating and non‑operating).

6. Warranty & Support

   • 3‑year limited warranty from Synology.

   • Firmware updates can be done via Synology’s DSM (DiskStation Manager), which helps maintain compatibility, stability, and often performance

7. Low Noise / Acoustics

   • Idle noise ~ 23 dB(A).

   • Seek / active noise ~ 27 dB(A).

What Makes It Strong / Advantages

• Reliability for NAS: The drive is designed for always‑on NAS use; high workload rating, high MTBF, tested for Synology environments.

• CMR (Conventional Magnetic Recording): This is better than SMR for many NAS workloads, especially when many writes or RAID rebuilds are involved.

• Firmware Integration: Being part of Synology’s own Plus/HAT3300 line means firmware updates can be pushed through DSM, simplifying maintenance.

• Low Power & Good Efficiency: For its capacity, it has modest power draw especially at idle; good for NAS units with multiple disks.

• Decent Sustained Throughput: Although not ultra‑fast, ~202 MB/s sustained transfer is solid for many use cases (media, backups, general file storage).

• Quiet / Moderate Noise: Idle and operating noise are relatively modest; good for home/office settings.

Ideal Use Cases

• Home NAS setups where media streaming, shared folders, backups are done regularly.

• Small/medium business environments where reliability is more important than ultra high performance.

• Environments where firmware updates integrated via Synology are an advantage (ease of maintenance).

• NAS enclosures with multiple bays where multiple drives run continuously — the efficiency (lower power, lower heat, quieter) adds up.
