1. The UniProt (=SwissProt+Trembl) monthly updated protein info database. We put these datafiles into a database. also makes available this data in XML form (same URL as below) but I find those too large to download/handle/process. The (smaller) .dat files are regular text files:

   size     URL   maxsize   OS    fs    description   length     format
Swiss-Prot  (1)    2.4 GB   linux  ext3  protein info  variable  free text (multiline)
Trembl      (2)   47.5 GB   linux  ext3  protein info  variable  free text (multiline)

  (1): Swiss-Prot (curated data): uniprot_sprot.dat
  (2): Trembl (uncurated data): uniprot_trembl.dat

Uniprot grows pretty fast too: see the graphs on the SwissProt and TrEMBL stats pages.

2. Sometimes it's necessary to munge a database dump (in text form). They can be 100s of GB.

3. Semi-continuously processed data-files vary from tiny to 1 GB (xml+csv, linux).
