Plus Series 12TB: specifications and dated store comparison →

A 12TB CMR option for a supported Synology NAS, with useful large-file copy evidence and audible activity to consider.

One 12TB HAT3310-12T · 3.5-inch SATA · CMR

This guide checks the exact HAT3310-12T column (family data sheet and the 23 April 2026 product specification), two original 12 TB write-ups (Kursors.lv desktop copy and CGMagazine migration), and current plus historical US listings. Blackvoid’s HAT3310 note is related context about the 8/12 TB vendor shift, not a 12 TB benchmark. ChooseCompute has not tested this drive. See the review evidence ↓

Synology Plus Series 12TB NAS hard drive

Is this 12TB drive right for your NAS?

A supported Synology NAS

Drive firmware can be managed from DSM on a supported system.[1]

A reason to consider it

Shared files and backup storage

12TB raw capacity with a 180TB/year workload rating.[1]

Check the workload and capacity

A quiet desk-side NAS

The finished enclosure has no controlled noise result here.[1]

Placement matters

A different NAS brand

Physical SATA fit does not establish support for the complete system.[2]

Check compatibility first

Living with it

Synology compatibility, capacity and everyday use

01

Check HAT3310-12T against your Synology NAS

This is the 12TB HAT3310-12T. It is worth considering when your Synology NAS lists this exact drive and you value managing drive firmware from DSM. Check that pairing before ordering.[2][1]

02

Plan usable space from 12TB raw capacity

12TB is raw decimal capacity. Formatting and your array layout reduce usable space. Keep an independent copy of important files; redundancy cannot undo an accidental deletion.[1]

03

Desktop copy speed is not NAS network speed

A direct desktop copy in the Kursors review stayed around 240MB/s. Treat that as one large-file workload, not a guarantee for a NAS network or small-file tasks.[3]

04

Audible activity in the DS923+

Kursors heard prominent drive activity in a DS923+. Choose the enclosure location with that in mind; the observation is not a calibrated noise comparison.[3]

05

Related: 8/12 TB Plus drives are described as Toshiba-based

Blackvoid reported that HAT3310 8 TB and 12 TB moved from Seagate-based HAT3300 parts to Toshiba-based hardware with Synology firmware, and that DSM 7.2 or newer was required when that article was written. Kursors likewise described HAT3310 as Toshiba NAS hardware with custom firmware. Those are identity/context notes, not a substitute for the 12 TB copy and migration tests above.[12][3]

06

Host compatibility is a policy check, not a SATA fit

HAT3310-12T is a 3.5-inch SATA drive intended for compatible Synology systems, with one-click firmware updates inside DSM on supported hosts. 2025-and-later Synology models and some DSM versions restrict or warn on third-party disks; older hosts still need the live compatibility list for this exact MPN. Kursors used four demo drives in a loaned DS923+ without RAID; CGMagazine migrated into a DS224+ JBOD over gigabit. Do not treat family marketing as a substitute for the current host list.[1][2][11][3][4]

A 240 MB/s desktop copy and audible NAS activity

Tested: Four demo HAT3310-12T drives in a loaned DS923+, without RAID or NVMe cache; separate desktop copy from an NVMe SSD on i9-13900K / Gigabyte Z790 / 32GB DDR5.

Applies to: Exact 12TB model; desktop copy is separate from NAS-network speed.

  • Drive activity sounded prominent during the NAS benchmark; this was a subjective observation.Source location: Four-drive DS923+ test, before desktop tests
  • Desktop charts on i9-13900K show sequential rates near or above the 281 MB/s rating in ATTO/CDM Q8, with AS SSD Seq about 266/259 MB/s. CDM was not a complete four-row run.Source location: Desktop benchmark screenshots

Migration to a DS224+ using JBOD

DS224+ JBOD migration without observed file errors. iSCSI CDM from that NAS is about 118 MB/s sequential, which is the network/iSCSI path, not a bare disk. A File Station overlay shows 241.9 MB/s at 0.1% of 10.02 TB; the article’s 3.2 TB USB sentence does not match that overlay, so the USB figure stays qualified. Gaming notes have no FPS.

Synology HAT3310-12T Plus Review

Tested: HAT3310-12T in a DS224+ (hostname ZubiDS224 on screenshots). JBOD migration from a TerraMaster F2-212 over gigabit; later iSCSI mount of the Synology volume into Windows for CrystalDiskMark; File Station copy UI also shown. Affiliate links disclosed; sample supply unstated.

Applies to: Exact model, migration experience; not an isolated disk-speed comparison.

Limits to keep in mind

  • JBOD provides no disk-failure redundancy.
  • iSCSI CDM is NAS + network + iSCSI, not an isolated HDD.
  • USB/File Station speed: overlay vs 3.2 TB prose disagree; path/direction ambiguous.
  • Gaming note is subjective with no FPS/latency.
  • Sample-supply arrangement unstated; affiliate links disclosed.

Before you buy

Current and historical HAT3310-12T listings and ownership costs

1 usable current main offer checked on 2026-09-10

Each current row keeps the selected main seller, condition, availability and only a price visible without a cart action. Null price means the main buy box hid it; every current fact is a dated observation that requires a fresh check before purchase.[10]

Budget for the complete storage plan

Include the number of disks needed for your array and a separate backup destination, not just the first drive.[1]

Check the seller as well as the price

Compare the exact model, new condition, shipping, return policy and regional warranty eligibility. A marketplace page may use a different seller from the store itself.[8][5]

Include running costs

Typical drive power is 3.30W at active idle and 6.85W in the specified random workload. Add the enclosure and other drives when estimating the whole system.[1]

Compatibility, capacity and backup questions

Does it work with every Synology NAS?

No universal claim is made here. Check HAT3310-12T against the compatibility list for your NAS and installed software before buying.[2]

Does HAT3310-12T use CMR or SMR?

HAT3310-12T uses conventional magnetic recording (CMR), according to the manufacturer's specifications.[1]

Can I use the speed rating as a file-transfer estimate?

Use it as a drive specification. Network speed, array layout, file size and disk position affect actual transfer rates.[1]

Does the three-year warranty protect my files?

The limited warranty covers eligible hardware service. It does not create a backup copy of the data.[1]
