Exact 36TB Seagate part-number reference

ST36000NM001M Seagate Exos 36TB Mozaic

Verified spec guide ·

ST36000NM001M is the exact 36TB Seagate Mozaic-family model covered by this procurement page. The goal here is to identify the part accurately, describe the host requirements and stop buyers from substituting a generic 36TB or 32TB Exos listing without checking architecture.

The model is documented as an SMR/ZAC host-managed zoned device. That makes it a storage-platform decision, not just a large SATA hard drive.

Quick answer

ST36000NM001M is a 36TB Seagate Mozaic-family SATA enterprise HDD with host-managed SMR/ZAC behavior, 1024MB cache, 7200 RPM and a five-year warranty class. Buy it only where the storage stack is qualified for zoned-write operation.

Workload rating is recorded per part number from Seagate's datasheet for that exact model, not blanketed across the line — two drives of the same capacity can differ because they are different generations. A dash means the figure is not stated for that listing. Recording technology comes from the manufacturer's published CMR/SMR list; a model absent from that list is shown as UNVERIFIED rather than guessed. Rows priced above 3× this line's in-stock median are flagged and excluded from the winner callout and from every median we compute.

Live acquisition math for exact matches

This table is computed from live DatacenterDisk rows when an exact in-stock match exists. It is intentionally blank for unavailable models rather than filled with stale prices.

No exact in-stock row is available right now. Use the availability table for nearby live alternatives, then re-check the exact model before ordering.

CheckModel suffix
Procurement consequenceST36000NM001M is the model covered here; Seagate also exposes other 36TB Exos M support suffixes.
CheckRecording behavior
Procurement consequenceSMR/ZAC host-managed behavior must be supported by the stack.
CheckSector format
Procurement consequence512e default with 4Kn switchability must match the host and existing pool.
CheckWorkload design
Procurement consequenceBest fit is controlled sequential or append-heavy bulk storage, not ordinary random-write workloads.
CheckFleet spares
Procurement consequenceDo not mix with CMR spares unless the pool is designed for that media mix.

Exact 36TB identification

Seagate's support ecosystem exposes 36TB capacity through more than one naming path. ST36000NM001M appears in the X/Mozaic 36TB documentation used here, while the Exos M support page has separate ST36000NM003K entries. Those strings should not be treated as interchangeable in procurement records.

The safe purchasing flow is exact model first, then interface and host behavior, then price. A title that says Seagate 36TB Exos or Mozaic 36TB is not enough for a storage fleet purchase.

Host-managed SMR implications

The 36TB product manual exposes sequential-write-required SMR zones. That is why this exact-model page keeps compatibility warnings above price. If the host stack cannot manage zones, the drive is not a drop-in replacement even if it physically connects.

For the right environment, the density is compelling. A 1PB raw target needs about 28 drives at 36TB instead of 32 drives at 32TB. In large fleets, that can reduce slots, shelves, HBAs, cable paths and rack footprint.

Who should avoid it

Avoid ST36000NM001M for ordinary NAS appliances, desktop storage, generic hardware RAID, VM datastores and any platform whose documentation does not describe host-managed SMR support for the exact drive class.

Buyers who need a conventional 32TB enterprise drive should compare Seagate Exos 32TB CMR and WD Ultrastar choices rather than assuming 36TB is the next compatible step.

Frequently asked questions

What is ST36000NM001M?

It is the 36TB Seagate Mozaic-family Exos model covered by Seagate's public 36TB documentation used for this page.

Is ST36000NM001M host-managed SMR?

Yes. The product manual used here describes SMR zones and ZAC host-managed behavior.

Is ST36000NM001M the same as ST36000NM003K?

No. They are different model suffixes in Seagate public support records and should be verified against their own data sheets before substitution.

Should I buy purely by the lowest price per TB?

No. Price per TB is the first screen, not the whole decision. Match recording method, interface, bay count, firmware support, warranty position and rebuild risk before accepting the cheapest row.
