What 16TB changes in a NAS plan
Its capacity can reduce the number of bays needed, but rebuild and restore planning becomes more important. Calculate formatted space, redundancy, snapshots and backup copies before deciding how many drives to buy.[1]

N300 16TB: specifications and dated store comparison →16TB decimal for up-to-12-bay home and small-business NAS systems, with the exact HDWG81GXZSTA revision kept separate.
One Toshiba N300 16TB HDWG81GXZSTA internal SATA hard drive. NAS enclosure and other drives sold separately.
This guide checks the exact HDWG81GXZSTA official column on Toshiba's July 2026 N300 sheet. 1 older US listing(s) are retained with their original observation dates; 2026-09-11 merchant PDP rereads were blocked or incomplete, so those prices were not refreshed. No suitable exact-MPN original test was adopted; related-family tests are summarized with their actual sample identities. ChooseCompute has not tested this drive. See evidence and test gaps ↓
Is 16TB N300 storage right for your NAS?
A 16TB-per-bay capacity plan
One drive provides 16TB decimal before formatting; redundancy and growth allowance still reduce practical headroom.[1]
Up-to-12-bay home and small-business nas systems
The official column rates up to 12 bays and 180TB/year read, written or verified. Footnote 4: host compatibility still varies; this is not a NAS vendor HCL.[1]
Quiet storage beside a desk
Published acoustic labels and review observations, when available, do not predict resonance or seek noise in your enclosure.[1]
A workload that needs proven latency or application speed
The evidence does not establish performance for every array, network, database or virtual-machine workload.[1]

Capacity, power, cooling and sound for HDWG81GXZSTA
What the 294 MB/s rating does and does not say
The rating is useful for checking the exact HDWG81GXZSTA column. It does not guarantee a network transfer rate or random-I/O result, and it should not be copied to a neighboring MPN.[1]
What still needs a real-world test
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.
Before you buy
Current and historical HDWG81GXZSTA listings and ownership costs
No usable current main offer on 2026-09-11
B&H, Amazon, Adorama, Newegg, Micro Center, Best Buy, Walmart and Connection pages were attempted on 2026-09-11 and returned challenges, 403s or incomplete bodies. Historical catalog rows keep their original checkedAt values and are not live offers.[1][2]
Compare the delivered unit and seller
Check HDWG81GXZSTA, new condition, seller, regional warranty channel, shipping and return terms. A marketplace product page does not by itself identify the current seller.[2]
Budget for the storage layout
A mirrored or parity-protected layout may require multiple drives, while a separate backup needs additional storage. Compare total delivered cost for the complete plan.[1]

HDWG81GXZSTA questions before buying
How much usable space will 16TB provide?
Less than the decimal label after formatting, and less again when the chosen redundancy layout reserves capacity. Leave room for growth and snapshots.[1]
What should I verify before ordering HDWG81GXZSTA?
Confirm the full MPN HDWG81GXZSTA, seller, new condition, NAS compatibility, firmware support, mounting fit, delivered price, and that the enclosure is within the official up-to-12-bay class. Recheck every historical merchant listing.[1][2]
Has ChooseCompute tested this drive?
No. This guide synthesizes manufacturer documents, retained merchant records and any clearly identified third-party original tests; each result keeps its setup limits.[1]
Does the warranty or MTTF tell me how long HDWG81GXZSTA will last?
No. The limited warranty is support coverage. MTTF is a population statistic, not a life estimate. Toshiba annualizes workload under 40°C ambient, and the 1,200,000-hour MTTF (AFR 0.73%) assumes 24×7 use with average HDA surface ≤40°C. HDA/case surface above 40°C may degrade reliability and reduce the warranty period. The 5–60°C drive-surface operating range is not a reliability guarantee at 60°C. Keep an independent backup.[1]
How many NAS bays is HDWG81GXZSTA rated for?
The official column says up to 12 bays. Footnote 4 says compatibility still depends on the host system; check the NAS vendor list for this complete MPN rather than treating the bay-class line as certification.[1]
