Identity
Compute and memory
Manufacturer specifications with configuration and evidence limits.
| Processor | AMD Ryzen AI Max+ 395 · 16-core[1] |
|---|---|
| Factory memory | 128GB LPDDR5x · max 128GB[1] Factory memory is kept separate from maximum supported capacity and from seller-installed upgrades. |
| Physical CPU cores | 16[3] |
| Factory memory | 128 GB[2][3] |
| Host memory ECC | Unknown — 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 path | No 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 limit | 128 GB (soldered LPDDR5x on this SKU)[1][5] |
| CPU threads and boost | 32 threads; up to 5.1GHz[1] |
| Integrated graphics | Radeon 8060S[1] |
| Official CPU power range | 70–90W[1] Processor power range, not measured whole-system consumption. |
| Memory speed | 8000 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.
| Cataloged drive-bay count | 5[1] M.2 positions are listed separately and are not silently added to SATA bay count. |
|---|---|
| Supported drive layout | 5 × 3.5/2.5-inch SATA HDD/SSD + 5 × M.2 NVMe SSD[1] |
| Replaceable storage drives | Yes — 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 expansion | Yes[3] |
| Official external drive enclosure expansion | USB4 peripheral connection; no branded expansion-enclosure compatibility list established[1] Air/Pro OCuLink and x16 expansion do not apply to MAX. |
| Physical M.2 slots | 5[3] |
| SATA without a mandatory model whitelist | Unknown — no mandatory whitelist published on opened pages[1] |
| M.2 without a mandatory model whitelist | Unknown — no mandatory whitelist published on opened pages[1] |
| PCIe expansion slot | No Air/Pro-style add-in slot documented; internal M.2 storage expansion only[1] |
| Factory OS SSD | 128 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 capacity | 5 × 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 lanes | 1 × 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.
| Installed Ethernet | 2 × 10GbE[1] Multiple ports do not guarantee one client the sum of their link rates. |
|---|---|
| Fastest installed single network port | 10 Gbps[3] |
| Official network upgrade path | Dual 10GbE installed; USB4 adapter support requires OS/device verification[1] No vacant Air/Pro-style NIC expansion slot is established. |
| USB4 ports | Front: 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 output | HDMI 2.1 FRL; up to 8K 60Hz / 4K 144Hz[1] Display capability is not a NAS transcoding guarantee. |
| Ethernet controllers | 2 × Realtek RTL8127 10GbE[1] |
Software and data protection
Manufacturer specifications with configuration and evidence limits.
| Factory operating system | MinisCloud 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 support | ZFS 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 interface | Yes — 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 target | Native 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 path | Partial — 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 backup | Yes — 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 snapshots | Yes — 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 retention | Unknown — 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 protection | Unknown — not established from opened MinisCloud documents[1][8] |
| Remote snapshot replication | Unknown — not established; client backup is not remote snapshot replication[1][8] |
| Native endpoint restore | Unknown — 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 path | Yes — 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 interface | Client dashboard for CPU, memory, disks and temperatures[10] LinuxLinks’ monitoring description does not establish a browser-accessible administration interface. |
| System log interface | Unknown — monitoring exists; a dedicated log viewer was not documented this round[1] |
Warranty and support
Manufacturer specifications with configuration and evidence limits.
| Standard warranty | 2 years[3] |

Physical, power and acoustics
Manufacturer specifications with configuration and evidence limits.
| Dimensions | 199 × 202.4 × 252.3 mm[1] |
|---|---|
| Weight | 5.8 kg[1] Official chassis specification; installed drives and accessories change deployed weight. |
| Power supply and consumption | Internal 250W supply; 100–240V AC, 50/60Hz[1] Supply rating is not idle or typical wall consumption; measured sample figures are discussed separately. |
| Acoustic conditions | No 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 inlet | Internal 250 W PSU, IEC mains (no external brick)[1][14] |
Hardware details
Manufacturer specifications with configuration and evidence limits.
| Other USB ports | 2 × 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. |
