Lossless compression routinely reduces 4D-STEM data by more than 10 times, with blosc_zstd offering comparable ratios to gzip-9 but 19-69 times faster compression and 1.9-2.6 times faster reads, though sustainable high-throughput will require inference-driven rather than raw-data representations.

Inference-Sufficient Representations for High-Throughput Measurement: Lessons from Lossless Compression Benchmarks in 4D-STEM
