I have a second-hand ReadyNAS Duo v1 (RAIDiator 4.1.12, 256 MB memory) with two SAMSUNG HD403LJ 372 GB drives in there. All my media on one drive, including my iTunes library, set to RAID, hooked it up to my Airport Extreme (A1354, latest firmware). In recent weeks it has gotten slower and slower and sloooooower, seeming to constantly be spinning, churning and working. Switching songs in iTunes takens forever, as does everything else. Do I just need to buy a new NAS box? New drives? A new "Cloud" external hooked up via USB2? A new router? I don't know jack about this stuff and don't care to learn it all. I just want a simple NAS or "cloud" external hard drive on my wireless network that I can access with speed from my Macbook Air, AppleTV, etc. What's the best, fastest-serving $150-200 fix/option? Having two drives for RAID purposes is nice, but I'm okay if I just got a single and backed up periodically on my own. I just want all my media in one place. My main thing is my HUGE music library that I want to keep on an external and access it all day long via home wifi to play music and it not be slow and suck. That's it. Also, it'd be nice to download movies onto it and have them play on my AppleTV.
