 ![Benchmarks performed on a machine with 2 Intel Xeon 2.00GHz CPUs, 32GB of RAM, and an SSD configured with RAID 0. The trajectory used for benchmarking was the YiiP trajectory from MDAnalysisData [@YiiP:2019], a 9000-frame (90ns), 111,815 particle simulation of a membrane-protein system. The original 3.47GB XTC trajectory was converted into an uncompressed 11.3GB H5MD trajectory and an uncompressed 11.3GB ZarrMD trajectory using the MDAnalysis `H5MDWriter` and *Zarrtraj* `ZarrMD` writers, respectively. XTC trajectory read using the MDAnalysis `XTCReader` for comparison. \label{fig:benchmark}](benchmark.png)
 
-![RMSD benchmarks performed on the same machine as \autoref{fig:benchmark}. YiiP trajectory aligned to first frame as reference using `MDAnalysis.analysis.align.AlignTraj` and converted to compressed, quantized H5MD (7.8GB) and ZarrMD (4.9GB) trajectories. RMSD performed using development branch of MDAnalysis (2.8.0dev) with "serial" and "dask" backends.

 *Zarrtraj* is capable of making use of *Zarr*'s powerful compression and quantization when writing ZarrMD trajectories. 
 The uncompressed MDAnalysisData YiiP trajectory in ZarrMD format is reduced from 11.3GB uncompressed
