Frequently Asked Questions (FAQs)
Q1: Can I use the HAT5300 in non‑Synology NAS?
Yes—it’s a standard SATA drive, but DSM-specific features like one-click firmware updates and optimized RAID behaviour require Synology systems.
Q2: Is the drive noisy?
It’s somewhat audible due to its 7200 RPM speed but remains suitable for server environments; quieter operation is found with 5400 RPM drives.
Q3: How does Persistent Write Cache work?
It writes data to onboard cache in a way that prevents loss or corruption during unexpected power outages.
Q4: Is a heatsink needed?
No, normal NAS airflow is sufficient. Only use external cooling in atypically hot environments.
Q5: What is the typical lifespan?
Rated for five years of continuous use and a workload of 550 TB per year, supported by MTBF of 2–2.5 million hours.
Q6: Can I mix this with other brands in a RAID?
Technically yes, but RAID arrays are more stable and predictable using identical, DSM-optimized drives.
