Everything You Need to Know BEFORE Getting a NAS - A Newbie's Perspective

NAS overview (what it is + why it exists)

• NAS (Network Attached Storage) is storage you can access over your home/network to upload/download files from devices on Wi‑Fi or wired Ethernet.
• NAS is often confused with a server: technically many NAS devices can run server software/apps, but not all servers are NAS.
• Cloud storage
  • Pros: very easy to set up (app + account).
  • Cons: cost scales with storage, and access speed depends on internet bandwidth—it can feel like renting long-term.
• HDD hoarding
  • Pros/cons: using many external drives can create messy maintenance (knowing what’s where, drive health).
• The video frames NAS as a middle ground:
  • Own the storage
  • Often fast (LAN speed)
  • More flexible than “at home only,” especially with remote access tools and self-hosted apps

Costs + maintenance tradeoffs

• NAS cost is largely upfront (device + drives + configuration) and requires more maintenance than cloud services.
• Drives are typically sold separately, so total cost can rise quickly.

Buying options / brands discussed

Main pre-built NAS brands mentioned:

• Synology
• QNAP
• TerraMaster
• ASUS Store
• UGREEN
• Ubiquiti

Synology (pros/cons)

• Seen as a leader in consumer NAS software: user-friendly and feature-packed NAS OS.
• Downside: described hardware is “mediocre,” and newer models (ending in 25) reportedly restrict supported drive brands to an approved list, often more expensive.

Ubiquiti (pros/cons)

• Relatively new to NAS; currently one main NAS product mentioned.
• Pros: simple UI, works well with other Ubiquiti gear, fits rack setups, “traditional NAS” feature set.
• Cons: fewer extra features; backup/connectivity options are more limited versus brands with broader standard support.

UGREEN (sponsor) + DH4300 Plus (features + use cases)

QNAP / TerraMaster / others

• Mentioned as having various options (especially in mid-range pricing), but discussed less in detail than Synology/Ubiquiti/UGREEN.

DIY / custom NAS options

• NAS can be any computer with NAS-capable OS (examples: TrueNAS, Unraid).
• Building is highly technical:
  • requires significant tinkering
  • reading and learning
• Also mentioned: turning a Windows/Mac machine into NAS via built-in OS options/software.
• Pre-built NAS units can sometimes run other operating systems too.

Key selection factors before buying

1) Size / drive bays

• NAS models range from 2 bays to 16+.
• 2-bay NAS may fill up quickly; you might later replace the NAS or migrate to larger drives.
• 4+ bays makes expansion easier (add drives instead of migrating everything).

2) Ports / connectivity

• Ports vary:
  • HDMI (media server use)
  • USB (attach external drives)
• Almost all NAS need Ethernet for network access.

3) NAS performance bottlenecks (network speed first)

• Common Ethernet speeds: 1GbE, 2.5GbE, 5GbE, 10GbE
• Warns that the slowest link limits throughput, including:
  • example: 1Gbps ≈ 125 MB/s
  • but practical bottlenecks often happen elsewhere (switch, client NIC, etc.)
• Recommendation: 10GbE may be overkill for most people; aim for 2.5–5GbE if possible.

4) Processor (NAS CPU)

• CPU impacts app performance and read/write speed, but comparisons are harder—suggests relying on benchmarks.

5) Drive types: HDD vs SSD vs NVMe

• HDDs (3.5”): high capacity, cheap; slower
• SATA SSDs (2.5”): faster than HDD but smaller and often more expensive
• NVMe (M.2): very fast, but less common in everyday NAS
• Suggested approach:
  • Mostly archival/family photos/videos: HDDs
  • Active editing / heavy file working: SSD/NVMe
• Warns against mixing SSD and HDD in the same RAID array (would defeat SSD performance goals); suggests using storage pools to keep them logically separate.

Drive arrays / redundancy (RAID and alternatives)

Why arrays matter

• Arrays split files into chunks across drives to improve performance and/or reliability depending on configuration.

Common options explained

• RAID 0: fastest/largest capacity; one drive failure kills all data
• RAID 1: mirroring; usable storage roughly equals one drive
• RAID 10: combination; survives one drive failure per mirrored pair
• RAID 5: distributed parity; survives one drive failure
• RAID 6: distributed double parity; survives two drive failures, but can be slower due to extra parity work
• Synology SHR/SHR2
  • Similar to RAID 5/6 but supports mixed drive sizes more flexibly
  • Uses the “largest-as-parity” concept rather than forcing everything to the smallest size
• ZFS
  • Mentioned as offering more resilience features
  • Found on TrueNAS (and not on some brands discussed)

Starting recommendations (practical rule of thumb)

• 2 drives → RAID 1
• 3 drives → RAID 5
• 4 drives → RAID 5 for smaller drives, RAID 10 for larger drives
• 6+ drives → RAID 6
• Larger drives + capacity tradeoff → RAID 10 option mentioned

Drive purchase guidance

• Recommends NAS-rated HDDs, not generic drives:
  • Western Digital: WD Red Plus / Red Pro (avoid “regular” WD Red)
  • WD Ultrastar also recommended
  • Seagate: IronWolf / Exos
• Suggests buying the largest capacity drives you can, because:
  • capacity runs out quickly
  • replacing/migrating data is painful
• For SSD side:
  • Use reliable SSDs (SATA or NVMe)
  • Recommend at least two SSDs for RAID mirroring
• Highlights tradeoffs between speed and cost.

Setup + core features after purchase

Typical setup flow:

1. Install drives
2. Connect NAS to network
3. Find NAS IP address and access via browser/setup wizard
4. Configure storage pools/arrays
5. Enable SMB for device access from other computers

NAS apps + self-hosted services (use beyond storage)

• Many NAS platforms include an app store; many apps are self-hosted (not publicly hosted on the internet).
• Examples used/recommended:
  • Tailscale: “VPN-like” tool to access NAS remotely (requires client apps on NAS + devices)
  • Plex / Jellyfin: media streaming server for files stored on NAS
  • Photo management app (“Image”): self-hosted Google Photos-like functionality
  • Home Assistant: smart home automation hub

External drives + networking access

• NAS can often connect external drives via USB and then expose them over the network like part of the system.

---

Security + reliability recommendations

• Use strong security: 2FA, strong passwords.
• Avoid exposing unnecessary ports directly to the internet.
• Use a UPS (Uninterruptible Power Supply):
  • Provides short battery time to let NAS shut down safely.
  • For longer outages, use UPS USB integration so the NAS auto-shuts down before battery depletion.
  • Notes UPS batteries are typically lead-acid and need replacement every few years.

---

Backup strategy (321) + backup architectures

The 321 method

• Keep 3 copies of important data:
  • at least one offsite (not in the same location)

NAS as primary storage changes the backup needs

• If you treat NAS as primary storage (like a shared drive), you may need more backup layers because NAS itself is the “source.”

Backup options by budget

1. Cheapest: external drives + cloud backup (plus cloud as offsite)
2. Budget NAS: backup devices to NAS, then NAS to a single large external drive (with drive rotation offsite every few months)
3. More expensive: second NAS offsite
4. Stopgap: “Frankenstein” mix of old drives + free cloud storage, but requires tracking and periodic drive health checks (booting old drives to ensure data integrity)

The creator’s example setup (analysis reference)

• Creator uses NAS as primary storage:
  • Older Synology 8-bay NAS for YouTube work (needs SSD speed for editing + enough capacity for archives)
  • UGREEN DXP 4800 Plus for personal life (photos, media, home automation, documents)
• Backups:
  • Both NAS backed up to Ubiquiti UNAS Pro
  • Plus offsite backup to UGREEN DH4300 Plus
• Advice:
  • stick to one NAS brand for easier transfers
  • cross-brand backups can become proprietary and hard to standardize
• Notes limitations:
  • Synology and UGREEN backups may use proprietary formats that don’t sync cleanly across brands
  • Ubiquiti backups described as more standard visually, but limited port/USB backup options and lack of common standards like rsync/“arsync”
• Solution used:
  • Open-source sync tool to keep NAS folders synced across devices
  • combined with Tailscale for remote/automated syncing

---

“What to buy” recommendations (starter ranges + examples)

• Absolute budget (~$400): UGREEN DH4300 Plus (4 bays, beginner-friendly apps)
• ~$400–$700:
  • Ubiquiti “Unass Pro”: 7 drive bays; requires SFP port for 10GbE (with adapters for Ethernet)
  • UGREEN DXP 4800 Plus
  • Synology DS925 Plus: praised for OS/app quality but criticized for drive lock-in; suggests older models (e.g., DS923 Plus) that allow more drive freedom
• Avoid Synology lock-down: UGREEN DXP 4800 Plus suggested for broader app support similar to Synology’s
• $800+: more capable NAS with 6+ bays, typically includes features like 10GbE, NVMe slots, stronger hardware; aimed at business-level needs and large data/project storage
• Reminder: drives are not included in NAS price—account for drive costs.
