FAQ

Which Synology NAS models are compatible with the HAT3300-4T?

The HAT3300-4T is part of Synology's Plus Series and is listed on the official compatibility page for many DiskStation and RackStation models. Check Synology's support site with your NAS model before purchase; most Plus-series units from 2019 onward are supported.

What recording technology does the HAT3300-4T use, and how does it differ from SMR?

This model uses CMR (Conventional Magnetic Recording), which writes without reading adjacent tracks first, avoiding the performance drops SMR drives can exhibit during heavy writes. CMR is more predictable for RAID rebuilds and frequent backups.

What warranty and distributor support do I get?

Hinkwong sells the Synology HAT3300-4T as Authorized Goods with a 3-year manufacturer warranty. For non-human failures within the warranty period, you can arrange a replacement through the Hong Kong distributor with your purchase receipt. Actual terms are subject to the manufacturer and distributor.

What do the MTBF and workload ratings mean for the HAT3300-4T?

MTBF of 1 million hours is a statistical average time between failures, not a guaranteed lifespan. The 180TB/year workload rating indicates the total amount of data the drive is designed to write annually. Both reflect suitability for always-on operation, though actual life depends on environment and usage patterns.

Can I update the HAT3300-4T firmware directly in DSM?

Yes. Synology's own drives support firmware checks and updates directly from Storage Manager in DSM, so you do not need to remove the drive and connect it to a PC. Back up important data before updating.
