I already have an alu macbook and alu imac, I have been running out of hard drive space and recently upgraded the macbook to 500gb. My issue now is backups. I have a huge iphoto library that is extremely important, I would also like to be able to use the back up device to stream media etc. I was considering a time capsule but for a couple of hundred dollars more (i'm currently in the us) I could but the low end mini. Would this be suitable for my needs? I would use it basically to run my other two computers iusing file sharing etc. Any advice? thanks.
