HAT5300-4T

Description

The HAT5300‑4T is part of Synology’s enterprise / NAS‑class hard drive lineup (the HAT5300 series). It’s a 3.5‑inch SATA III drive, with 4 TB capacity, spinning at 7,200 RPM, and designed for continuous (24/7) usage in Synology NAS / server environments.

Key Features

1. High Capacity & Form Factor

   • 4 TB capacity in a 3.5‑inch form factor.

   • SATA III interface (6 Gb/s) for wide compatibility.

2. Performance

   • 7,200 RPM spindle speed for better throughput vs “green” or slower drives.

   • 256 MB buffer / cache, helping with burst transfers and smoothing out read/write caching.

   • Sustained data transfer rate of about ~243 MiB/s typical.

   • “Up to ~23% faster sequential read” when used in Synology NAS compared to comparable drives.

3. Reliability & Durability

   • Designed for 24/7 operation; intended for heavy duty, enterprise or NAS environments.

   • Workload rating: ~ 550 TB transferred per year.

   • Mean Time To Failure (MTTF): ~ 2.0 million hours (some listings say up to ~2.5 million under certain conditions)

   • Persistent write cache technology: helps protect data in the event of power loss.

4. Integration & Management

   • Tight integration with Synology DiskStation Manager (DSM); firmware updates can be managed through DSM, simplifying maintenance.

   • Extensive validation & stress testing for Synology systems: hundreds of thousands of hours of internal testing.

5. Warranty & Support

   • 5‑year limited warranty from Synology.

   • Good certifications / build quality suited for NAS/enterprise use.

6. Power & Operating Conditions

   • Typical idle consumption: ~ 4.07 W. Under activity (random read/write) ~ 7.76 W.

   • Operating temperature: ~ 5 °C to 60 °C.

   • Physical robustness (shock, vibration specs etc) to suit use in multi‑drive racks / NAS.

What makes it special / how it’s optimized

Some of the features that distinguish the HAT5300 series (including the 4T model) are:

• Designed for Synology systems: The drive firmware is integrated with Synology’s DSM OS; there is automatic firmware update via DSM to ensure compatibility and performance.

• High sequential read performance in multi‑user / multi‑client environments: Synology claims up to 23% faster sequential reads in its NAS systems for these drives (thanks to firmware and system optimization).

• Reliability and durability: High MTBF, high workload rating, persistent write cache to help mitigate risk of data corruption in case of power loss.

• 24/7 operation capability. These are not “desktop drives” but intended for continuous operation under load

Suitable use cases

This drive is well‑suited for:

• NAS (Network Attached Storage) systems that are used constantly: file servers, backup servers, media servers.

• Business or small data center environments where uptime and reliability matter.

• Multi‑user/concurrent access workloads, e.g. serving many clients, streaming, virtualization.

• Environments where Synology’s DSM is used and full integration (firmware, monitoring) is desire
