Our take on the Synology HAT5310-20T 20TB SATA 6Gb/s 3.5-Inch Hard Drive

The Synology HAT5310-20T is a 20TB 3.5-inch SATA hard drive built for Synology NAS systems. It is a helium-sealed enterprise-class drive with a 512MB cache and a workload rating suited to always-on storage. It suits owners of large Synology arrays who want drives on Synology's own compatibility list and firmware support. Against general-purpose desktop drives it offers more capacity and NAS tuning; against third-party enterprise drives it trades a wider price spread for tighter integration and validation with Synology systems.

Questions and answers

Is this drive compatible with my Synology NAS?
It is on Synology's own compatibility list for many of its NAS models, and Synology provides firmware updates for it. Check your model's list before buying, since older or smaller units may not be listed.
Is it CMR or SMR?
It is a conventional magnetic recording (CMR) drive, not shingled. That matters for RAID rebuilds and sustained writes.
How is it different from a desktop hard drive?
It is tuned for always-on NAS use, with helium sealing, a 512MB cache and a workload rating above desktop drives. Desktop drives are cheaper but not built for continuous multi-drive operation.
Can I use it in a PC or external enclosure?
Yes, it is a standard 3.5-inch SATA drive. It needs a SATA connection and a bay or enclosure that fits a 3.5-inch drive.
Should I buy one large drive or several smaller ones?
For a NAS, several drives in a redundant array protect against a single failure. One 20TB drive gives capacity but no redundancy.
Where is the Synology HAT5310-20T 20TB SATA 6Gb/s 3.5-Inch Hard Drive cheapest?
