I see the first of the one terabyte storage starting to show up in
places like BestBuy etc.

Long term, I want to archive all or most of my CD collection
( most in .wav format...though increasing #'s in FLAC and SHN )

Has anyone out there transferred most or all of their collection on to
a hard drive ( of any size ) ?....and is there specific software that makes
the playing of individual album titles user friendly.

I'm probably going to wait until the drives have multiple terabyte storage before purchasing one....but I'm just trying to size the problem of transferring and playing the music.

Ultimately, I'd like to give back my "music room" to my family for their use....
..and I'd like to retire far away in the country, by a lake, with a huge hard drive and thousands of hours of music on it :>

Thanks,
Doug

Being in the Coast Guard we are looking at a similar situation with audio files from Search & Rescue cases. As such we have talked through audio archiving issue through & through. The problem with any external hard drive is the ability to lose your data, either while transferring to it, from it (in your case for possibly burning a copy later, etc), or simply by it sitting latent for any given amount of time.

So consider this. Figure out how much storage space you need to archive everything (700 mb per cd), 4 gb (?) per DVD.If it fits on one 1 Terrabyte hard drive, buy a backup of the same size & duplicate everything on to both. That way if one crashes you have a back up. Pull the back up file from the back up external drive, copy & paste in to the original to restore.

If you want your storage space to go further, why not convert & save everything as FLAC? All you need to play FLAC from the hard drive (whih you imply is where you would be pulling your music from to play it on either a stereo/ computer/ whatever) is WinAmp Media Player with the FLAC codec & you're set. You would also be able to use WinAmp to play DVD's (vid).

i'm going to have to go through a similar process in the near future das; i'm beginning to see Disk rot happenining on some of my oldest disks now (most of them are less than 7 years old but are still rotting, ick).

my plan so far is to mirror whatever size drive that install (meaning, i'm going to have two of the exact same drives with duplicate data on them). That way, there is only a slight chance I will lose both at once. (Of course, i'm considering offsite backup too......), I have found this to be cheaper and more reliable than DVD storage in the long run. Start with the Terabytes, then add more if you need to. Also, the cost of those things will go down, WAY down in the next year. I'm working with one data center who has exabytes worth of storage.....

The problem with mirroring is that it can clog your I/O channels as all the writes have to
happen twice. IF you don't have your mirrors on separate I/O channels it can really
hurt performance.

It could affect how fast you can R/W from your CD/DVD readers/Burners

RAID is a better solution for time critical I/O.

Raid is an array of discs that looks like one big disc. RAID = Redundant Array of Independent Drives

Usually a Raid controller or the main I/o channel writes the data to many discs in a striped pattern accross
many drives.

Parity data is also written so If one drive fails, then the failed drive is replaced and the data on
the failed disc is restored using the parity bits. So a single drive failure will not lose any data.
A hardware RAID has a dedicated controller doing the striping. Software RAID is from special software
to spread the data and parity bits accross the drives.

The RAID controller does the striping of the data and by using many discs at the same time
the aggregate throughput is higher than an individual disc.

As opposed to mirroring, which just makes a second copy and is half as slow (on average) than
an individual disc.

Both have purposes. Some Operating Systems can't boot from a raid device, so a mirror might
be more appropriate, while using a RAID only for data on that system may be the way to go.

The Trade off with RAID is that you lose some RAW capacity to handle the striping and parity for
recovering the data should an individual drive fail.

I don't buy drives larger than 500GB. Too many eggs in one basket. FLAC
is good for audio, winamp and other players have a FLAC plugin so you can
playback without decoding. I make a directory listing of each drive so that
I can find things when the drives are offline. I'm taking about external USB
drives. I've even used these for trading, send off an empty 500 GB drive and
get back a bunch of stuff to listen to/watch.

there are websites that offer for a fee, storage space for what ever you want. Music, pix, data, whatever. It's pretty safe unless the internet or the website crashes.
