The NASync DH Series is great for beginners and home users purchasing a NAS for the first time. It offers massive storage, user-friendly features, and competitive specs at an accessible price.

The NASync DXP Series is built for enthusiasts, creators, and professionals. It delivers stronger processing power and supports advanced functions like Docker and virtual machines across all models.

Only if you need massive storage growth, high-speed professional workflows (e.g., video editing), or advanced data redundancy (RAID 5/6 for multi-drive failure protection). For everyday home use—backups, photos, streaming—a 2-bay NAS is simpler, cheaper, and fully sufficient.

For personal use, RAID 5 offers the best balance between redundancy and usable storage space; RAID 6 provides stronger protection but requires the capacity of a second hard drive. If you’re unsure which setup aligns best with your storage goals, our guide on how to choose the best RAID for NAS breaks down the pros and cons of each configuration.

Yes. Install just 2 drives in your 4-bay NAS and use all core features (backups, AI photo sorting, streaming).

When adding drives later: Always match the original drives’ model and capacity to avoid wasted space, performance drops, or rebuild failures. If you’re unsure which types of drives pair best with your setup—especially when expanding—our guide on choosing the right NAS drives breaks down compatibility, performance, and long-term reliability in simple terms.

Yes, but not recommended: mixing sizes wastes significant capacity (limited to the smallest drive in RAID) and increases failure risk due to drive mismatch. For reliability and max space, always use identical drives.

For a 4-bay NAS, Toshiba N300, Seagate IronWolf, and Western Digital Red Plus are common choices; they are designed for 24/7 operation and RAID configurations. If you’re also looking to minimize noise in a home setup, consider one of the quietest NAS drives for home use that combine reliability with near-silent performance.

Rubber mounting pads, slower fan profiles, quieter hard drives, and an isolated location can significantly reduce operational noise. And if you want to go a step further, you can follow additional techniques outlined in our guide on how to reduce NAS noise, which covers practical tweaks and hardware tips to keep your system running whisper-quiet.

No. RAID only guards against drive failures—it mirrors errors instantly (e.g., accidental deletions or ransomware spread to all drives). Always keep separate backups offline or in the cloud (follow the 3-2-1 rule: 3 copies, 2 media types, 1 offsite).
