Nothing inherently wrong with it and it of course depends on your storage needs. Online services are so mature now that I don't really hesitate on storing data in someone's data centre now, though, so I can't quite imagine having to plug a hard drive in.......
With that said, if you aren't already, you should periodically make sure those old drives still work. No point in having backups if you can't backup from them!
