Quick answer
What to know before buying
Every model in Toshiba's cited May 2026 N300 range uses CMR and 7,200 RPM. The current family runs from 4TB to 22TB, but capacity alone is not a complete identifier. Toshiba lists two current 14TB profiles: the retail HDWG51EEZSTA has 512MB cache and supports up to eight bays, while the bulk MN11ACA14TS has 1024MB cache and supports up to twelve. Current 16TB to 22TB models also use MN11 identifiers. Use the lookup and match the complete listing number before applying speed, power, cache or bay specifications.

Current N300 model lookup
Select a capacity to see the current cited retail and bulk identifiers plus the main specification differences.
The current list is all CMR, but the model number still matters
Toshiba's cited May 2026 N300 data sheet marks every current capacity as conventional magnetic recording. That removes the CMR-versus-SMR uncertainty that exists in some consumer hard-drive ranges. It does not make the models interchangeable. Power, acoustics, MTTF, cache, bay support and packaging identifier change across the capacity ladder, and 14TB has two current profiles.
Retail searches can return older N300 generations alongside the current range. A statement attached to HDWG780EZSTA should not automatically be applied to HDWN180XZSTA or another 8TB revision. Use the lookup tool for current identifiers and read the seller's complete model. When the suffix is absent, ask the seller or treat the specification as unverified.
Current 4TB and 6TB models
The current 4TB retail model is HDWG740EZSTC with bulk identifier MN10ADA400ES. The 6TB retail model is HDWG760EZSTA with bulk identifier MN10ADA600S. Both are CMR, 7,200 RPM, rated up to 281MB/s with 512MB cache, support up to eight bays and carry a 180TB-per-year workload rating with three-year warranty.
The 4TB model lists 7.43W operating, 4.14W active idle and 34dB typical idle. The 6TB lists 8.19W operating, 4.92W active idle and the same 34dB typical idle. At these capacities, buyers should compare the total number of drives required because a larger 8TB or 12TB mechanism may provide lower array cost, fewer bays and a better acoustic profile.
Current 8TB and 10TB models
The current 8TB retail identifier is HDWG780EZSTA and its bulk identifier is MN10ADA800S. The 10TB retail identifier is HDWG71AEZSTA with bulk identifier MN10ADA10TS. Both list 281MB/s, 512MB cache, 9.07W operating, 5.74W active idle and 34dB typical idle, with support for up to eight bays.
These are performance-oriented air-filled capacities and should not be assumed quiet because they belong to the same family as the 20dB higher-capacity models. The 8TB price may look attractive, but a four- or eight-drive living-room array can be intrusive. Use the exact acoustic requirements of the installation before choosing based on price per terabyte.
Current 12TB and two different 14TB profiles
The 12TB retail and bulk identifiers are HDWG51CEZSTA and HDWG51CUZSVA. They use CMR, 7,200 RPM, 512MB cache, a 281MB/s rating and support up to eight bays. The 12TB model lists 6.85W operating, 3.30W active idle and 20dB typical idle.
At 14TB, the May 2026 sheet lists two distinct current profiles. Retail HDWG51EEZSTA is rated at 294MB/s with 512MB cache, support for up to eight bays, 7.38W operating and 3.77W idle. Bulk MN11ACA14TS is also rated at 294MB/s, but has 1024MB cache, supports up to twelve bays and lists 6.94W operating and 3.66W idle. Do not merge their specifications merely because both are 14TB N300 drives.
Current MN11 16TB, 18TB and 20TB models
The current 16TB, 18TB and 20TB bulk identifiers are MN11ACA16TS, MN11ACA18TS and MN11ACA20TS. Each uses CMR, 7,200 RPM, 1024MB cache, a 294MB/s rating and support for up to twelve bays. The latest cited sheet does not provide retail identifiers for these three models.
MN11ACA16TS lists 6.94W operating and 3.66W idle. MN11ACA18TS lists 7.41W and 4.16W, while MN11ACA20TS lists 7.62W and 4.35W. All three list 20dB typical idle and a 1.2-million-hour MTTF class. Retail availability and warranty route can vary for bulk-only stock, so seller and condition deserve careful checking.
The 22TB model remains the performance ceiling
The current 22TB MN11ACA22TS supports up to twelve bays, carries 1024MB cache and is rated up to 298MB/s. It remains CMR, 7,200 RPM, 180TB/year and three-year warranty, with a cited 1.2-million-hour MTTF, 7.62W operating, 4.35W active idle and 20dB typical idle.
The 22TB model is the capacity and transfer-rate ceiling, but it is no longer the only 12-bay or 1024MB N300. Current MN11 models from 14TB through 22TB share those two attributes. Check NAS compatibility, firmware and physical mounting before using high-capacity drives in an older chassis.
Retail, bulk and regional identifiers
A retail model normally includes consumer packaging, while a bulk identifier may arrive in antistatic and protective shipping material without the same box. Bulk does not automatically mean used or inferior, but warranty processing and seller responsibility can differ. Marketplace titles often omit the distinction or place one identifier in a variation selector.
Verify the complete number on the invoice and drive label after delivery. Check the serial with Toshiba's warranty process where available and keep packaging until the disks pass extended testing. If multiple drives are bought, record which serial occupies each bay. That information simplifies failure diagnosis and replacement handling later.
How to use this database safely
Select the capacity in the lookup, compare the returned current identifiers with the retailer page and then verify the connected NAS compatibility list. Do not use model-number matching as proof of authenticity or warranty. It is a specification tool that reduces accidental comparison of different generations.
When an older model appears at a lower price, find its own official data sheet before assuming it shares the current rating. Older N300 stock can still be a valid purchase, especially when the seller and warranty are strong, but the comparison should use its own power, acoustics, cache and workload information. Cloudzat labels current and older revisions separately whenever the source data allows.
Treat the model list as a dated reference, not a permanent catalogue
Toshiba can revise capacities, regional packaging numbers and technical specifications after this page is published. The review date is therefore part of the answer. A model absent from the May 2026 sheet is not automatically counterfeit or unsuitable; it may be an older generation, a region-specific identifier or a product introduced after the cited document.
For a purchase made months later, compare the model against Toshiba’s current regional support material and the NAS manufacturer’s compatibility list. Cloudzat should update the database when a new official sheet changes the family. Until then, the lookup is most reliable for identifying the cited current range and flagging listings that need separate verification.
