Plus Series 16TB: specifications and dated store comparison →A 16TB CMR Plus-series drive for a listed Synology NAS; confirm the HCL row, DSM build, and backup plan.
One 16TB HAT3310-16T · 3.5-inch SATA · CMR
This page combines Synology's current Plus Series datasheet and product table, the 2026-09-11 compatibility-list rows, and dated US listings. We have not tested HAT3310-16T ourselves. No original lab benchmark of this exact 16TB SKU was adopted. One Kakaku user report describes four of these drives in a stock DS923+ RAID 5 array; that is a single configuration, not a noise ranking. See evidence and test gaps ↓
Sampled Plus models show a published recommended HCL row, with a DSM 7.2-64570 install note.[8][2]
16TB decimal raw capacity and 7200 rpm / 281 MB/s typical maximum are manufacturer ratings, not network results.[1]
Follow any specification for its full conditions and sources.
Living with it
This is the 16TB HAT3310-16T, not HAT3320-16T and not Enterprise HAT5310-16T. On 2026-09-11 the Synology HCL listed it as published/recommended for DS923+, DS224+, DS1522+ and DS1825+ internal trays, with a note to upgrade DSM to 7.2-64570 or later before installing. Recheck your exact NAS; listings can change.[8][2][1]
16TB is decimal raw capacity. Formatting and RAID/SHR reduce what you keep. A Kakaku user reported 41.9TB on four of these drives in RAID 5 on a stock DS923+; that figure is their array, not a promise for your layout. Keep an independent copy of important files.[1][11]
Synology rates 24/7 use and 180 TB/year of host reads/writes/verifies, with a typical maximum sustained transfer of 281 MB/s. HCL lists firmware package MG09_MN09_SATA_1402.ftd. That name hints at Toshiba MG/MN lines but is not a license to reuse N300 charts. HAT3310-12T CGM CrystalDiskMark (iSCSI from a DS224+, SEQ1M Q8T1 118.41/117.97 MB/s) and an in-progress File Station copy (241.9 MB/s at 9.4 GB of 10.02 TB) stay 12TB NAS-path results. Hardwareluxx 4TB 5400 rpm power (startup 23.92 W / idle 1.9 W) is a different SKU.[1][8][12][13][14]
Datasheet idle/seek figures are manufacturer typical dB without distance or weighting. 38Elm's 2025-02-03 Kakaku report (DS923+, 4× HAT3310-16T, RAID 5, Ubuntu NFS) said idle was fine among quiet PCs, while writes stayed noisy for a while. That is one room and one array, not a dBA ranking.[1][11]
We have verified the specifications, but have not found an original test that we can reliably apply to this exact model. The advice above follows the documented features; performance, noise and long-term reliability are not independently established here.

No. Check HAT3310-16T on the HCL for your exact NAS. Sampled Plus models listed it on 2026-09-11 with a DSM 7.2-64570 note. HAT3320-16T is a different HCL row.[8][2]
No. Synology specifies conventional magnetic recording (CMR) for the Plus Series, including HAT3310-16T.[1][2]
Use it as a manufacturer typical maximum. Network, RAID/SHR, file size and disk position change what you see.[1]
The limited warranty covers eligible hardware service from the receipt date in the purchase country. It is not a backup. Logged over-temperature can end drive coverage.[9][1]
No. They are individual user reports. The detailed RAID 5 note is useful for idle-versus-write noise in that DS923+ setup only.[11]
