I have a 1TB MyBook Home which is used to store photographs (raw files and the big edited TIFFs) and my iTunes library which is now full. So I am looking at getting another TB of storage, plus the same again for backup. As I only have a MacBook I am looking at Firewire 400 solutions, at least for the main drive, and have narrowed it down to these options: 1) MyBook Home II 2TB - This is the 2TB version of what I have now, so it would become my main drive. My Current one will then become the backup drive, along with the pair of 500GB drives onto which it is currently backed up. [Cost: £196.59] 2) MyBook Studio II 2TB - The same as the above option, except it contains 2x 1TB drives in a RAID 0 configuration. Although stripping offers no resiliency, it is no worse than the single drive solution. [Cost: £195.09] 3) A pair of MyBook Home II 1TB - One would just simply be the backup for the other. [Cost: £185.28] 4) MyBook Home II 1TB plus WD Elements 1TB - As a backup drive the Elements would only be connected when syncing, so I can accept it being USB only. It would be faster to sync than connecting it over the same firewire connection anyway. [Cost: £161.60] The last option is simply being considered because it is the cheapest. It, along with option 3, is also a 'collect in store' option so I could get it today without waiting on shipping Otherwise though there is not much price difference between the first three options, I am just not sure which is best way of going: single drive, stripped drives, or physically separate drives? Option 3 should be more resilient as one drive failure will not affect the other half. But it means another device to plug in, both to the mains and my single firewire connection, and will take up more space. Incidentally, although I could set the Studio to work in RAID 1 and essentially act as its own backup, I want to be able to keep the backups in a different location to the main drive so this is not an option. Any suggestions would be most appreciated. Thanks, Michael.
