Compute and memory

Manufacturer specifications with configuration and evidence limits.

Compute and memory specifications
ProcessorAMD Ryzen AI Max+ 395 · 16-core[1]
Factory memory128GB LPDDR5x · max 128GB[1]

Factory memory is kept separate from maximum supported capacity and from seller-installed upgrades.

Physical CPU cores16[3]
Factory memory128 GB[2][3]
Host memory ECCUnknown — N5 MAX 128GB: evidence is still needed for host-path ECC in the factory configuration; on-die ECC does not establish host ECC. This remains unknown, not a confirmed no.[1]

Evidence boundary: the opened exact-model official page did not publish or establish this field. The citation records the checked evidence boundary, not a confirmed feature. N5 MAX 128GB: evidence is still needed for host-path ECC in the factory configuration; on-die ECC does not establish host ECC. This remains unknown, not a confirmed no.

Official memory upgrade pathNo user-upgradeable SODIMM; capacity is a factory LPDDR5x SKU (64 GB or 128 GB)[1][2]

Official pages: onboard LPDDR5x 256-bit. 128GB is a different US SKU, not a DIMM upgrade of the 64GB unit.

Official memory limit128 GB (soldered LPDDR5x on this SKU)[1][5]
CPU threads and boost32 threads; up to 5.1GHz[1]
Integrated graphicsRadeon 8060S[1]
Official CPU power range70–90W[1]

Processor power range, not measured whole-system consumption.

Memory speed8000 MT/s default; 8533 MT/s overclock setting[1]

Official table distinguishes default from overclock. The marketing headline’s 8533 figure is not the default configuration.

Storage and expansion

Manufacturer specifications with configuration and evidence limits.

Storage and expansion specifications
Cataloged drive-bay count5[1]

M.2 positions are listed separately and are not silently added to SATA bay count.

Supported drive layout5 × 3.5/2.5-inch SATA HDD/SSD + 5 × M.2 NVMe SSD[1]
Replaceable storage drivesYes — slide-out 3.5/2.5-inch trays; hot-swap not claimed[1]

Official Air/Pro/Max pages and NASCompares/SMZDM photos show tool-less or slide-out bays. Hot-swap while powered is not established.

M.2 expansionYes[3]
Official external drive enclosure expansionUSB4 peripheral connection; no branded expansion-enclosure compatibility list established[1]

Air/Pro OCuLink and x16 expansion do not apply to MAX.

Physical M.2 slots5[3]
SATA without a mandatory model whitelistUnknown — no mandatory whitelist published on opened pages[1]
M.2 without a mandatory model whitelistUnknown — no mandatory whitelist published on opened pages[1]
PCIe expansion slotNo Air/Pro-style add-in slot documented; internal M.2 storage expansion only[1]
Factory OS SSD128 GB OS storage; 4 of 5 M.2 slots free on IT Pro’s 64GB unit[5][4]

IT Pro spec table: 5x NVMe (4 free).

SATA positions and listed per-drive capacity5 × 3.5/2.5-inch SATA; up to 32TB each[1]

Manufacturer capacity listing is not a promise that every drive model is compatible.

M.2 form factors and electrical lanes1 × 2280 Gen4 x4; 4 × Gen4 x1 (one supports 2230/2280, three 2280)[1]

128GB OS SSD occupies one x1 position; four positions remain for user storage.

Network

Manufacturer specifications with configuration and evidence limits.

Network specifications
Installed Ethernet2 × 10GbE[1]

Multiple ports do not guarantee one client the sum of their link rates.

Fastest installed single network port10 Gbps[3]
Official network upgrade pathDual 10GbE installed; USB4 adapter support requires OS/device verification[1]

No vacant Air/Pro-style NIC expansion slot is established.

USB4 portsFront: 1 × USB4 40Gbps; rear: 2 × USB4 v2 80Gbps[1]

All three list DisplayPort 2.0 and 15W output. Link rates do not establish sustained NAS or peripheral throughput.

HDMI outputHDMI 2.1 FRL; up to 8K 60Hz / 4K 144Hz[1]

Display capability is not a NAS transcoding guarantee.

Ethernet controllers2 × Realtek RTL8127 10GbE[1]

Software and data protection

Manufacturer specifications with configuration and evidence limits.

Software and data protection specifications
Factory operating systemMinisCloud OS; ZFS-based, advertised as Beta[1][10]

Feature maturity depends on the installed release. Recent original reviews required a desktop/mobile app; an advertised web client should not be assumed available.

RAID supportZFS pools; RAID0/1 and parity RAID advertised; RAIDZ options require sufficient disks[1][10]

LinuxLinks screenshot: RAIDZ1 ≥3, RAIDZ2 ≥4, RAIDZ3 ≥6 disks. The five-bay chassis cannot form a six-disk RAIDZ3 using SATA bays alone; no hybrid-pool assumption is made.

Backup through the graphical interfaceYes — Backup app in MinisCloud clients[1][8][10][4]

Official educ_content shows a Backup app that creates scheduled jobs from Windows/macOS/iOS/Android clients to MinisCloud. LinuxLinks found the tool basic: LAN backups from a computer or Samba share to the NAS, not a copy of files already on the NAS.

Backup to an independent targetNative NAS-to-external-target backup not established[10]

Client-to-NAS backup does not protect the NAS against its own loss. LinuxLinks could not back up files already on the NAS through the Backup app.

Documented restore pathPartial — ZFS snapshot rollback advertised; file-level restore wizard not fully documented this round[1][8][10][4]

Official snapshot copy promises instant rollback. LinuxLinks Backup page did not show a restore-to-endpoint procedure.

Scheduled backupYes — Backup jobs accept a schedule in official client docs[1][8][10][4]

Official educ_content shows a Backup app that creates scheduled jobs from Windows/macOS/iOS/Android clients to MinisCloud. LinuxLinks found the tool basic: LAN backups from a computer or Samba share to the NAS, not a copy of files already on the NAS.

Restore from snapshotsYes — official ZFS snapshot rollback (build-specific)[1][8][10][4]

Official N5 pages and educ_content describe ZFS snapshots with point-in-time rollback. Exact retention policy, immutable lock, and remote replication were not established from the opened documents.

Version retentionUnknown — snapshot feature exists; retention policy not documented on opened pages[1][8][10][4]

Official N5 pages and educ_content describe ZFS snapshots with point-in-time rollback. Exact retention policy, immutable lock, and remote replication were not established from the opened documents.

Immutable protectionUnknown — not established from opened MinisCloud documents[1][8]
Remote snapshot replicationUnknown — not established; client backup is not remote snapshot replication[1][8]
Native endpoint restoreUnknown — endpoint backup jobs exist; restore-to-PC procedure not fully documented[1][8][10][4]

Official educ_content shows a Backup app that creates scheduled jobs from Windows/macOS/iOS/Android clients to MinisCloud. LinuxLinks found the tool basic: LAN backups from a computer or Samba share to the NAS, not a copy of files already on the NAS.

Official system update pathYes — in-OS update prompt observed on N5 Pro MinisCloud[10][1]

LinuxLinks was prompted to update MinisCloud during pool setup on an N5 Pro. Exact channel for Air/Max builds not separately documented.

System status interfaceClient dashboard for CPU, memory, disks and temperatures[10]

LinuxLinks’ monitoring description does not establish a browser-accessible administration interface.

System log interfaceUnknown — monitoring exists; a dedicated log viewer was not documented this round[1]

Physical, power and acoustics specifications
Dimensions199 × 202.4 × 252.3 mm[1]
Weight5.8 kg[1]

Official chassis specification; installed drives and accessories change deployed weight.

Power supply and consumptionInternal 250W supply; 100–240V AC, 50/60Hz[1]

Supply rating is not idle or typical wall consumption; measured sample figures are discussed separately.

Acoustic conditionsNo comparable exact-configuration official noise rating established[1][10]

Related measurements use different memory, drives, operating systems and microphone conditions; see the evidence discussion.

Power inletInternal 250 W PSU, IEC mains (no external brick)[1][14]

Hardware details

Manufacturer specifications with configuration and evidence limits.

Hardware details specifications
Other USB ports2 × USB 3.2 Gen2; 1 × USB 2.0; internal USB 3.2 Gen1[1]

Marketing calls the internal port Gen2, but the detailed table says Gen1; the detailed table is retained.
