Synology HAT3300 - 3.5" NAS HDD - 2TB SATA
About Synology Plus - 3.5" NAS HDD
Synology's Plus Series is a 24/7 NAS-class hard drive line designed for home and small office Synology systems. The lineup spans three sub-series (HAT3300, HAT3310, HAT3320) under a single Plus Series datasheet, with capacities running from 2TB to 20TB. All capacities use CMR recording, a 6 Gb/s SATA interface, and 512e sector formatting, and ship with a 3-year limited warranty.
Specs by Capacity
| Capacity | MPN | RPM | Cache | Workload | Sustained Throughput | Drive Design |
|---|---|---|---|---|---|---|
| 2TB | HAT3300-2T | 5,400 | 256MB | 180 TB/yr | ~180 MB/s | Air |
| 4TB | HAT3300-4T | 5,400 | 256MB | 180 TB/yr | ~202 MB/s | Air |
| 6TB | HAT3300-6T | 5,400 | 256MB | 180 TB/yr | ~202 MB/s | Air |
| 8TB | HAT3320-8T | 7,200 | 512MB | 300 TB/yr | ~281 MB/s | Helium |
| 12TB | HAT3310-12T | 7,200 | 512MB | 180 TB/yr | ~281 MB/s | Helium |

Reliability
The HAT3300 sub-series (2-6TB) is rated for 1 million hour MTBF, while the HAT3310 and HAT3320 sub-series (8-20TB) carry a 1.2 million hour MTBF. Synology validates each drive with over 500,000 hours of compatibility testing on Plus, Value, and J series DiskStations before shipping. CMR recording and DSM firmware integration make the Plus Series a safe pick for ZFS, SHR, and standard Synology pool configurations.
Sub-Series Differences
The HAT3300 is the budget tier for the smaller Plus, Value, and J series enclosures, prioritizing cost over throughput. The HAT3310 and HAT3320 step up to 7,200 RPM and helium sealing for the higher-capacity, higher-uptime side of the lineup. The HAT3320-8T is the standout on workload (300 TB/year vs the 180 TB/year of the rest), making it the right pick when 8TB matches the desired capacity and write volume is heavy. The HAT3320-20T takes the larger 1GB cache and the highest sustained throughput in the line.
Best for: Synology DiskStations running 24/7 in home and small office settings, especially Plus, Value, and J series enclosures.
Avoid if: Your workload exceeds 300TB/year (use the Enterprise SATA series), or you need throughput above 295 MB/s.
