Standard desktop hard drives are not designed for the 24/7 operation and vibration environment inside a NAS enclosure. NAS-rated drives like the Seagate IronWolf and WD Red Plus include firmware optimisations for RAID arrays, vibration sensors, and longer warranty periods.

SSD Cache Drives for NAS
Adding an NVMe SSD cache to your NAS dramatically improves random read/write performance. The Seagate IronWolf 525 and WD Red SN700 are purpose-built for NAS caching, with high endurance ratings suited to constant write operations.
Frequently Asked Questions
Can I use a regular desktop HDD in my NAS?
You can, but it’s not recommended long-term. Desktop drives lack the vibration tolerance, firmware optimisations, and workload ratings needed for reliable 24/7 NAS operation.
How much storage for a home NAS?
A 2-bay NAS with 2x4TB drives in RAID 1 (mirror) gives 4TB of redundant storage — enough for most home users.
