I have bought a Zyxel NSA-220 NAS case last year to have a secure backup of my pictures, videos and MP3s. I have set up two 500 GB SATA drives in RAID1 mode (mirror).
Now, this works all very well. If one of the disks breaks down, there’s always the other one.
But there are still things that worry me:
- If I really have to replace a drive, will any drive with equal capacity work? What if there are no drives with equal capacity on the market?
- What if the NAS hardware itself breaks down – will I be able to just attach the drives to a PC and rescue the contents (I guess they’re Linux EXT3 formatted)?
Backups are still a difficult thing to plan. What do you think – is a NAS system the way to go, or is it easier to just put the drives into a PC (which would have a higher power consumption)? Any ides appreciated. What do you do?
