I have a new post (https://aras-p.info/blog/2023/02/03/Float-Compression-5-Scie...) comparing zfp, fpzip, spdp, ndzip, streamvbyte libraries for compressing this same data set. All in lossless, single threaded mode so far (just like all the other experiments before).
zfp performance is... "underwhelming" to say the least :( (fpzip is pretty good though, if only a bit slow at decompression). Maybe zfp is much better on 3D or 4D data, and/or in lossy mode. Which might be a topic for a future post.
