Q: Do NAS units come with hard drives included?

The vast majority of NAS units sold in this category are diskless — the price covers the enclosure, processor, RAM, and OS only. You'll need to purchase hard drives separately. Budget for NAS-rated drives (WD Red Plus, Seagate IronWolf) rather than desktop drives; they're designed for 24/7 operation and vibration tolerance in multi-drive enclosures. A few models like the Synology BeeStation are the exception, shipping with built-in storage.

Q: How many bays do I actually need for a home setup?

For most home users, two bays is the practical minimum — it allows RAID 1 mirroring for basic redundancy. Four bays give you more flexibility: RAID 5 for better capacity efficiency, or the option to expand storage without rebuilding the array. Unless you're storing a very large media library (10TB+) or running a home lab, a 4-bay unit will serve you for years. Six or more bays is overkill for personal use.

Q: Can I use any hard drive in a NAS, or do I need specific drives?

Technically you can use any SATA drive, but we strongly advise against desktop drives in a NAS. Desktop drives aren't rated for continuous operation and can trigger RAID errors due to their error recovery behaviour (TLER/ERC). NAS-rated drives — WD Red, Seagate IronWolf, Toshiba N300 — are tuned for 24/7 use, vibration resistance, and NAS-compatible error recovery. Most manufacturers publish compatibility lists; always check your specific NAS model before buying drives.

Question 1

Accepted Answer

The vast majority of NAS units sold in this category are diskless — the price covers the enclosure, processor, RAM, and OS only. You'll need to purchase hard drives separately.

Question 2

What's the real difference between Synology and QNAP?

Accepted Answer

Synology prioritises ease of use and software polish; QNAP prioritises hardware features and flexibility. DSM (Synology's OS) is more intuitive and has a better app ecosystem for typical home and SMB tasks — photo management, cloud sync, backup. QNAP's QTS offers more granular control, better virtualisation support, and more exotic connectivity options, but it has a steeper learning curve. If you're not a power user, Synology is the safer choice. If you want to run VMs, containers, and custom network configurations, QNAP rewards the effort.

Question 3

Is RAID the same as a backup?

Accepted Answer

No — and confusing the two is one of the most dangerous mistakes NAS owners make. RAID protects against hardware failure (a drive dying), but it offers zero protection against accidental deletion, ransomware, or fire and theft. A proper backup strategy follows the 3-2-1 rule: three copies of your data, on two different media types, with one stored offsite. Your NAS is the primary storage; a separate backup device or cloud service is the backup.

For most home users, two bays is the practical minimum — it allows RAID 1 mirroring for basic redundancy. Four bays give you more flexibility: RAID 5 for better capacity efficiency, or the option to expand storage without rebuilding the array.

Most manufacturers publish compatibility lists; always check your specific NAS model before buying drives.

Question 6

What should I watch out for when buying a cheap NAS?

Accepted Answer

The main pitfall with budget NAS units is buying underpowered hardware that becomes frustrating within a year. ARM-based processors with 1GB RAM are fine for basic file sharing, but the moment you add Plex, a download manager, and a backup job running simultaneously, performance collapses. Also watch for models with no expansion slots (no M.2, no PCIe) — you're locked into the hardware as-is. Buffalo units in particular are very affordable but offer limited software support and no upgrade path. Buy for where your needs will be in three years, not where they are today.

Question 7

Is a NAS worth it in 2026 when cloud storage is so cheap?

Accepted Answer

Yes — for most users who store more than a few terabytes, a NAS pays for itself within 2–3 years compared to equivalent cloud storage subscriptions. More importantly, a NAS gives you full control over your data, no monthly fees, and local network speeds that cloud storage can't match for large file access. The two aren't mutually exclusive: many NAS units sync to cloud services (Backblaze B2, Amazon S3) as an offsite backup layer, giving you the best of both worlds.
