Comment (by knarf):

 I also agree that enabling compression is a good idea, and I go along with
 Ian that a compression level of 1 is almost as good as 9 and would be more
 conservative in terms of computation. I just wish there would be better
 compressions available in stock hdf5 because one argument against using
 gzip-compression is that compressing the uncompressed h5 files using
 something else later (bzip2 or xz) saves more space (but also makes the
 files unreadable using stock hdf5). Nevertheless, enabling compression by
 default is probably best.

 Checksums are implemented a while now, but I don't know how widely they
 are used. I regularly forget to enable them. I don't see a reason against
 making them default too.
