Synology HAT5310-16T 16TB — Enterprise SATA Drive Built for Synology NAS
16TB · 3.5-inch SATA 6Gb/s7200 rpm · 1 GB buffer550 TB/year workload2.5M hours MTBF
The Synology HAT5310-16T is a 16TB 3.5-inch SATA 6Gb/s enterprise hard drive running at 7,200 rpm with a 1 GB buffer and a 550 TB per year workload rating, designed and validated by Synology for continuous operation in its own NAS and SAN servers. It sits in the Enterprise Series alongside the HAT5300 and HAT5320 models, uses 512e sectors and conventional magnetic recording, and carries a 2.5 million hour MTBF with a 5-year manufacturer term that includes technical support and hardware replacement. Synology also builds firmware update delivery for these drives directly into DSM. Typically in stock with fast delivery across Cyprus.
Compatibility — check before buying:
Synology markets the Enterprise HAT drives as purpose-built for Synology servers, with deep hardware and software integration and one-click drive firmware updates through DSM. In a QNAP, TrueNAS or generic server this is still a perfectly good enterprise SATA drive, but you get none of that integration and no firmware update path. Check Synology’s own compatibility list for your exact NAS model before ordering — drive validation policy is enforced on newer enterprise units. Do not confuse it with HAS5300-16T, which is the SAS version and will not work in a SATA-only bay, or with HAT3310-16T, which belongs to the lower-workload Plus Series. Supplied as a bare enterprise drive — no rails, screws, cables or retail box.
Best For
✓ Synology enterprise NAS and SAN servers
✓ 24/7 business file and virtualisation storage
✓ RAID arrays that need CMR for predictable rebuilds
✓ Backup targets with heavy sustained write volumes
✓ Deployments where DSM-managed drive firmware matters
✓ High-capacity expansion of an existing Synology array
Key Features
550 TB per year workload rating
Roughly three times the workload rating of a typical NAS-class drive, which is what separates the Enterprise HAT series from the Plus Series in day-to-day duty cycles.
2.5 million hours MTBF
Synology publishes a 2.5 million hour MTBF for the 16TB model, backed by a 5-year limited warranty that the company states includes technical support and hardware replacement services.
512e CMR with a 1 GB buffer
Conventional magnetic recording with 512e sectors and a 1 GB buffer — the combination that keeps RAID rebuilds and sustained sequential work predictable, unlike shingled recording.
Built into the DSM ecosystem
Synology validates these drives against its own hardware and delivers drive firmware updates through DSM with a single click, which no third-party drive in a Synology chassis can offer.

Frequently Asked Questions
Singular Expert Insight
Buying Synology drives for a Synology NAS is one of the few cases where first-party storage genuinely buys you something beyond a logo: validated compatibility, and drive firmware updates delivered through DSM rather than through a vendor utility you have to boot separately. On newer enterprise units that validation is enforced, so it is worth checking the compatibility list before you commit either way. On the numbers, the HAT5310-16T is a proper enterprise drive rather than a rebadged NAS one — 550 TB per year against roughly 180 TB per year for a NAS-class drive, and 2.5 million hours MTBF against 1.2 million. Two honest caveats. Synology does not publish load/unload cycles or an unrecoverable read error rate for it, which enterprise buyers building a qualification document usually want, and its two official documents give different sustained transfer figures — 295 MB/s in the family datasheet, 281 MB/s in the newer model sheet. We publish 281 and say why. Within the range, the HAT5320 covers 4, 8 and 24 TB and the HAT5300 covers 12 TB; if your workload is lighter and the chassis is a Plus-series unit, the HAT3310 is the cheaper and correct tier.
Buyer’s Guide
Buy it if
You run a Synology enterprise NAS or SAN server, you want validated first-party drives with DSM-managed firmware updates, and a 550 TB per year workload with 2.5 million hours MTBF and a 5-year manufacturer term matches the duty cycle you are planning for.
Skip it if
You are building on QNAP, TrueNAS or a generic server — you pay for integration you cannot use. Skip it too if your bays are SAS (you need HAS5300), if your unit is a Plus-series NAS with a lighter workload (HAT3310 is the right tier), or if you need published UBER and load/unload figures.
Also consider
Synology HAT5310-20T or HAT5320-24T for more capacity in the same series; HAT5320-4T or -8T for smaller enterprise arrays; HAS5300-16T if your chassis takes SAS; or the Toshiba N300 range if the array is a general-purpose NAS rather than a Synology enterprise unit.
