I recently started doing a bunch of music importing on my rev. a 1.8 ssd. I must say I am quite impressed with the ~24x apple lossless import speeds I am seeing. this ssd kicks butt. Its quite a bit faster than my old 2.4 imac or white macbook
Got a tip for us?

Import speed shouldn't really be as much of HD/SSD speeds as it is CD drive speeds and/or CPU. Of course, importing to lossless will be faster because there is only a format conversion going on. AAC and MP3 are slower because they are being resampled by the CPU before being encoded, which is why the speeds are slower than lossless.
Interesting, though why it's faster than an iMac.
Anecdotally, I have an old P3 1.2 Sony Laptop. Lossless import speed was ~16x, AAC-256 was about 6x, so Lossless was about 2.5x faster than AAC.

As I understood it, there is some encoding going on with Apple lossless, as the file size after import is smaller than the total CD file size? It's just that it's not a lossless format similar to TIFF for images. I could be totally wrong...
Yeah, the file is compressed and encoded, making it smaller, but with a lossless format, all of the original information is retained.
Using your TIFF analogy, Lossless encoding is similar to something like a adding a TIFF to a zip file. It's file size is smaller, but all of the original data is there. The unzipping process (decoding) restores all of the data to recreate the original. Lossy encoding, like MP3, AAC and WMA are like converting the TIFF to a JPG. Some data is discarded and can never be recovered.
