Upfront Cost vs Monthly Fees
A 2-bay NAS with 2x 4TB drives costs ~£400-500 upfront (NAS unit + drives). Google One 2TB costs £80/year. iCloud+ 2TB costs £107/year. The NAS breaks even in 4-5 years but provides 8TB raw (4TB usable in RAID 1) vs 2TB cloud — and you own the hardware.
5-Year Cost Comparison
NAS (8TB raw): £500 upfront + £30 electricity = £530 total. Google One 2TB: £400 over 5 years. iCloud+ 2TB: £535 over 5 years. Dropbox Plus 2TB: £600 over 5 years. A NAS provides 4x the usable storage at similar 5-year cost.
The Best Approach
Use both. A NAS for primary storage and local backup. Cloud storage (even a free tier) for off-site backup of critical files. This 3-2-1 backup strategy (3 copies, 2 media types, 1 off-site) provides the best data protection.
Frequently Asked Questions
Is a NAS cheaper than cloud storage?
Over 3-5 years, a NAS provides significantly more storage per pound than cloud subscriptions.
Can a NAS replace Google Drive/iCloud?
For local storage and backup, yes. Synology Drive and QNAP cloud apps replicate cloud sync features. You lose the convenience of built-in phone backup integration.
