Objections about 1 TB disks

Hmm, i thought a little bit about the Hitachi 1 TB disk announcement. I think, there will be many problems with this hard disks:

• This harddisk should be only selled in pairs of two to home users. For home users the only feasible way to backup one of this beasts is: having another one to replicate one content to a second.
• This beast should be only selled to owners of Mac OS X 10.5 or Solaris 10 systems. You really want ZFS on this beasts, when can´t afford, that your read at least one incorrect byte from the disks after reading once or twice the data of disk.
• Has anybody thought about finding your stuff on your harddisk after storing it. For example a year after you stored it? Directories and Files seems a bad choice. I think we need Honeycomb@Home soon.
• With such a beast you can really go for a "snapshot after any file change". Mac OS X Time Machine on steroids

I really think, that 1 TB disk for home users will give us a complete new class of problems … but some nice chances as well.
