HAT5310-8T

Synology 8TB HAT5310 SATA III 3.5″ Internal Enterprise HDD

Product Description — Synology HAT5310‑8TB

The Synology HAT5310‑8T is an enterprise‑grade hard disk drive (HDD) designed for use in Synology NAS servers and other 24/7 storage systems. It’s part of Synology’s HAT5300 / HAT5310 line, which emphasizes reliability, performance, and durability in demanding conditions. Interface: SATA III (6 Gb/s) interface for connection to SATA host controllers, Form Factor & Speed: 3.5‑inch drive, spinning at 7,200 RPM and Cache / Buffer: 256 MB buffer size to help smooth data transfers and improve caching for frequent reads/writes.

Key Features

1. Enterprise‑Grade Durability & Reliability

   • Rated MTBF (Mean Time Between Failures) of ~ 2.5 million hours.

   • Designed for 24/7 operation with a workload rating of up to 550 TB/year.

   • Built‑in persistent write cache technology to help protect data in case of sudden power loss.

2. High Performance for Sequential Data Tasks

   • 7200 RPM spindle speed.

   • 256 MB cache (buffer) to assist with smoothing large transfers.

   • High sustained sequential throughput (~ 230‑260 MB/s) depending on workload.

   • Firmware + software optimization with Synology DSM for multi‑client sequential performance boosts (~23%) over similar drives.

3. Synology Ecosystem Integration

   • Automatic firmware updates via DiskStation Manager (DSM).

   • Rigorous internal testing: over 500,000 hours of stress/validation with Synology devices.

   • Capacity & Form Factor

   • 8 TB capacity.

   • Standard 3.5‑inch form factor with SATA III (6 Gb/s) interface.

   • Power, Environmental & Warranty Specs

   • Typical power draw: ~ 9.2‑9.3 W during read/write; ~ 5.6 W in idle.

   • Operating temperature range: approx. 5°C to 60°C; non‑operating storage much wider.

   • Physical robustness: vibration & shock tolerance (operating & non‑operating) aligned to enterprise NAS standards.

   • Warranty: 5‑year limited warranty from Synology.

Strengths

• High durability: Designed for enterprise or 24/7 usage; high workload rating means it can handle large amounts of writes/data per year.

• Good sequential performance: The ~230‑260 MB/s sustained throughput is solid for large file transfers, backup, media streaming etc.

• Synology / NAS integration: Firmware & persistent write‑cache features reduce risk of data corruption, especially under power loss or in multi‑client NAS environments.

• Long warranty: 5 years is good for enterprise/NAS HDDs
