Frequently Asked Questions

What's the difference between NAS drives and regular drives?

NAS drives (like WD Red or Seagate IronWolf) are designed for 24/7 operation in multi-bay enclosures. They include vibration resistance, firmware optimized for RAID arrays, and higher workload ratings than consumer desktop drives.

Should I use CMR or SMR drives in my NAS?

CMR (Conventional Magnetic Recording) drives are strongly recommended for NAS use. SMR drives can cause severe performance issues during RAID rebuilds and heavy write operations.

How many drives do I need for a NAS?

For basic redundancy, start with 2 drives in RAID 1 (mirroring). For more storage with protection, 4+ drives in RAID 5 or RAID 6 is ideal. Buy the largest drives your budget allows to minimize cost per usable gigabyte.
