I want to make my own Time Capsule, ie a wireless network storage unit that will work with our 2 Macs running OS 10.5. I also want the NAS to be RAID 1 capable, which is not a feature that Time Capsule has. Ideally, the unit will be compatible with Time Machine (HFS+ format). I've spec'd out the D-Link DNS-323 NAS enclosure, two 1 TB SATA drives, and the D-Link DIR-655 wireless router, all for about $420 Canadian dollars. While the 323 does work with Macs (based on numerous forum postings), it's not clear to me whether it will work wirelessly - no one that posted about it mentioned that they were using the unit wirelessly. I don't think the 323 supports HFS+ format, so it won't be compatible with Time Machine, but I could use other back up software to get around this if I had to. But if anyone knows of a better DIY solution, I'd like to hear about it. The Time Capsule is very expensive for the amount of storage space you get, which is also the case with other NAS RAID 1 capable products I see in Apple Stores. I'm not sure that those products would work wirelessly either. What started as a simple idea has become more complicated than I expected at first. Can someone shed some light on any of this for me? Thanks in advance!
