This article covers 【NAS用HDD】Synology HAT3300-6T [6TB 3.5" SATA 5.

Overview

The Synology HAT3300-6T is a 6TB 3.5-inch SATA hard drive engineered specifically for Synology NAS systems. Spinning at 5,400 RPM with 256MB cache and a maximum transfer rate of 202MB/s, it prioritizes stable 24/7 operation over raw speed. An MTTF of 1 million hours and an annual workload rating of 180TB/year place it well above desktop HDDs in durability. As part of Synology's Plus series, this drive guarantees firmware updates through DiskStation Manager (DSM) and full compatibility validation. It is an excellent choice for home or small-office NAS setups where data integrity matters more than peak performance.

Connectivity & Compatibility

The HAT3300-6T uses a standard SATA 6Gbps interface and fits any 3.5-inch drive bay. While physically compatible with any SATA port — including other NAS brands or desktop PCs — official firmware updates and workload guarantees apply only when used inside a Synology NAS. For best results, install it in a Synology enclosure that supports DSM.

Product Info

Launched in mid-2023, the HAT3300-6T sits in the mid-range price tier for 6TB NAS-grade HDDs. Warranty is 3 years. No accessories are included beyond the bare drive. It is available through , major electronics retailers, and Synology authorized resellers. Its market position is that of a premium first-party HDD for Synology users who want guaranteed compatibility and seamless DSM integration, at a premium over third-party NAS drives.

Best Use Cases

Long-term Synology NAS owners — If you plan to keep your NAS running for years, the official firmware updates and verified compatibility reduce headaches. Ideal for storing photo libraries, video archives, and other irreplaceable data. Small office or home server operators — The 180TB/year workload rating supports multiple concurrent file accesses. However, avoid this drive for heavy random I/O workloads such as database servers; a 5,400 RPM drive is not suited for that. * Users who will not repurpose the drive — If you are building a Synology NAS from scratch, this is the most trouble-free choice. But if you might move the drive to a different NAS brand or a desktop PC, consider cheaper alternatives like WD Red or Seagate IronWolf.
