Hi all Im in need of some kind of network device for storage and/or backups. I currently have 1 Macbook Pro, 1 Windows XP machine and 1 Windows 7 machine. One of these Windows machines will probably be swapped out with a Mac mini or iMac in the next year to year and a half. Im looking for something that I can back up all the computers to and also access the data on the network device from all computers. Some of the other requirements would be the ability to stream audio, video, pictures to something like an Apple TV or something similar. So far, I have it broken down to 4 items that Im looking at. Id like to hear some thoughts on these item and if anyone has any other suggestions, please let me know. Option 1 - 1TB (current generation) Time Capsule This option would probably end up being the easiest and cheapest. I do need to swap out my router with a new one that offers gigabit speed, and this includes it. Id just have to pick up a switch or 2. The things that Im not crazy about is that there is no redundancy with the hard drive, only 3 LAN ports (but not too big of an issue), and the questionable reliability. The previous gens seem to have issues with reliability. Option 2 HP EX490 This option is the most expensive, but it definitely offers a great amount of expansion. Id need to buy at least 1 more hard drive to setup some type of redundancy on the server and Id need to get a new router (most likely D-Link 655 or 825). I like the HP unit because its small compact design and its supposed to work out of the box with a Mac and Windows clients. Also, if you need to you can take a drive out of the system and slave it off to get data off of it. Option 3 Build my own Window Home Server This option is like the HP EX490, but would probably end up being cheaper and could be the most expansive depending on which components I choose. Im not sure how it will work with a Mac and the EX490 has special Mac plugins for it to work with Time Machine. OPTION 4 D-Link NAS 323 With this option, Id still need to pick up a new faster router, and a pair of 1 or 1.5TB drives. I understand that the setup and configuration is fairly easy. The drives are formatted with a proprietary format so I cant just go slave a drive if I need to. It definitely doesnt have as many options that the other options have either. It has a very small compact design. So if anyone has any input or any other suggestions, please post them. The only thing that Im not really into is building a linux, openNAS or openFiler PC. Thanks in advance.
