The 20 GB HD on my 1999 G4 Desktop makes one aware of how fast storage technology and pricing have been changing.
Went a bit over board with compiling an iTunes library, ripping, storing and organizing a large CD collection. Apple Lossless saves a little space over .aif music files and compilations are bit perfect. Re-imports, editing, conversions to other formats and lossy codecs like AAC is possible without degrading the quality, compared to an mp3 only library. Also takes up 10 times the space as mp3! I paid for every one of those bits and I'm not going to toss 90% of them forever! CD quality is the minimul archival qualty I perfer to store songs with.
Filled up a 200 GB HD with an itunes library using Apple Lossless. Went with a 400 GB HD, since investing all that time in ripping CD's to a hard drive it's foolish to not have it all cloned on another HD. I've read to many posts in MacRumours about "my HD broke" and what a catastrophe and/or waste of time to recover/find or duplicate all the downloads from scratch. I don't even care about the price much anymore with very large 400-500GB external FW/USB going for ~$150- 250. Space is just so cheap that storing in a high quality format isn't an issue. Having some extra room for movies or video on another partition works well.
It seems very important to keep a complete itunes library on a single hard drive and not having to split the itunes song files across multiple drives, so a 400GB external FW/USB Seagate gave the 200GB OWC itunes library room to grow. On that move I realized how important it is to have a backup so got a 500 GB seagate drive.
This time I realized that USB and FW are solid, especially usefull having a complete OS and application clone Drive, ready to boot from a 20 GB partition. The bootable clone is backed up regularly with "Super Duper", for peace of mind idiot proofing.
However the ATA drive technology is on it's way out and nearly all new drives in latest gen Macs are SATA technology drive.
SO... I bought a 500 GB SATA drive with the intention of housing it externally, but it fits fine INSIDE that big old G4 case and connects to all my current configuration with only a $70 SATA PCI card. I easily mounted the 500 SATA internally with one skinny SATAe cable attached to one of the optional internal SATA connectors.
The new SATA drive speed seem a little slower than the FW, but when I get a new Power Mac, I'll just pop in that 500 GB SATA HD, doing temporary itunes Library/boot clone duty and be ready for super FAST data transfers.
I'm just amazed that this _huge_, 500GB, late generation SATAII technology, will even work in a 1999 G4, and provide a plug and play bridge to a new Mac that will be able to use the Fast SATA drive fully.
Still think external ATA HD (FW) performance may be a bit more solid on older Power Macs and my G4, as well as being a bargain. An ATA drive purchase at this point is an investment in old technology. SATA drives seem like a useful component that appears very easy to transfer to a current brand new Mac Pro. -
