How to manage a big itunes library?


I have had a mac mini running itunes for about 2 1/2 years now. The inevitable has happened, my first drive has failed, at least it's icon has stopped showing on the desktop and I can't access the files.

I had a feeling this would eventually happen. I have the files backed up, but this does create a headache to fix it. The files were originally ripped on 250GB drives and the backups are on 500s. I have 5 250GB drives and one 500GB drive, all pretty much full. I have a pretty big collection, about 5000 or so CDs.

I need advise on a solid solution for this type of setup. There are some pretty big drives comming out but I just don't know what would be the best option.

Also this might seem stupid, but I am wondering if there would be any loss in quality in a copy of the original rip vs the original???

If you want a more seamless backup you may want to consider one of the less expensive RAID solutions that use very simple interfaces. In this scenario you would have a slightly larger RAID unit as your primary music library. The RAID unit contains several raw hard drives which easily slide in and out of the unit. The hardware / software can make one or more of those drives a 'redundant' backup of the main drive, and continually back it up as the main drive grows (within the capacities of the enclosed drives of course). In the event of a drive failure, which is inevitable with any drive, you'd simply slide out the failed drive and slide in a new one. The RAID system should never miss a beat and would immediately put the backup into use should the main fail, and would immediately backup to the drive you slide in to replace the failed drive. At best it is a constant ongoing process. Drawbacks are the larger size, more noise (not an issue if you are using a WIFI solution), and greater initial expense (one of the current crop of affordable RAID solutions may run around $800 initially, but then you only will have to replace raw hard drives (cheap). Another suggestion would be to buy the slightly more expensive and longer-lasting drives like G-Tech, but that doesn't mean they'll necessarily never fail - all drives will eventually fail. In general the larger TB drives are less reliable overall than the moderate drives. 500GB is my flavor of choice. TB drives are more often two or more 500's in a case together. They make more noise, are slower read/write, and are more prone to early failures in general. A quick read of any real-world reviews should prove that out. Not to say that there are not exceptions.

Good luck.
One other suggestion is consider adding hard drive coolers to each drive. These are fan-based coolers that mount directly on the drive. I picked up 4 recently for my systems; they were $5 each. They went on quickly and lowered the hard drive temp of every drive by 10 to 15 degrees centigrade. Since heat speeds up the failure process it is not a bad idea (though it does not replace backups.)
I am wrestling with the similar issues. If you haven't done so, I suggest visiting Computer Audiophile for a fairly active discussion of HD alternatives, backup strategies, etc.
I've had my eye on one of these for awhile and may pull the trigger before the year is out.

It's basically a simplified RAID system that utilizes up to four drives of any size. There is redundancy built in so when one drive fails your data is protected and the bad drive can be replaced on the fly.

I'm thinking of buying the newer Firewire 800 model and buying four 1TB Seagate or Maxtor drives for total storage of 2.7TB.
I am looking at the Drobo too. I want a solid solution. I am guessing I will have a library of well over 3 TBs when finished so I need something big which means 6-8TBs with backup.

Do you know if the Drobo is loud?

It is nuts to think this stack of drives I have is basically going in the garbage. Not really but I won't be using them, nor would I trust them.
