AIFF vs Apple Lossless Ripping

Ripping my CDs under AIFF is the best then?

   I have to rerip over 3000 CDs. Not looking forward to this!!!!

in a previous post, I was trying to critical listen to my ref system using my iPod with 128k, and was laughed at :). 

So using aiff would be much better?  I will start as soon as I get the time. 

Pecan I put the CDs in and when prompted, click "replace" or just delete the old album, and rip again??  What is recommended?  Thank you and I look VERY forward to your relies in this subject. 

Why not rip your CDs to ALAC which is Apple's version of FLAC?  You get much smaller file sizes, about 5% of original, no data is lost, and all of your devices seem to work well with ALAC.  I don't see where AIFF offers anything of value to you...

Please excuse my typo in the last post, the file sizes would be about 50% of original, NOT 5%...

I only have these options when I insert cd into my cpumpuers cloud drive (external)

aac -which everything I have is ripped to

aiff
apple lossless
mp3
wav encoder

for aiff , there's options. Sample rate, sample size, and channels I can choose from.     Best options???

AAC is compressed like MP3 (but better sound quailty).  WAV doesn't have ability to store metadata (track names etc.).  AIFF shouldn't have any options, being uncompressed.  Your choice is between Apple Lossless (ALAC) and AIFF.  ALAC is about 50% smaller than AIFF.  I store everything in ALAC because I use Apple computer and Iunes, but also because my wireless streaming to Airport Express uses ALAC as format (avoiding additional conversion).  Be advised, that ALAC and AAC files have the same extension .mp4  and the only way to distinguish between the is to read file info in I tunes or compare the size (AAC will be many time smaller).  On my phone and in my car I use AAC 256kbs VBR.
