@Blosc2 makes compression even better for tomography in synchrotron facilities in Europe by allowing up to 2x better compression ratio, helping already good codecs to shine even more, without almost no loose in perceived quality. Read our paper on how we achieved this: blosc.org/docs/LEAPS-I...

Difference in perception when using blosc2+grok for a 2x better compression ratio.
