Genomic sequencing data represents the fastest-growing and most computationally demanding healthcare data category, with the Healthcare Data Storage Market reflecting the infrastructure investment required to store, process, and analyze the whole genome sequences, exomes, and transcriptomes that precision medicine programs, clinical genetics services, and research biobanks are accumulating at rapidly increasing scale.

Whole genome sequencing generates approximately thirty to one hundred gigabytes of raw data per patient sample, with the bioinformatic processing pipeline — alignment to the reference genome, variant calling, annotation, and interpretation — requiring substantial computational resources and producing intermediate files that may be stored or discarded depending on reanalysis plans. The question of whether to retain raw FASTQ files versus processed VCF variant files has major storage cost implications, with raw data retention enabling future reanalysis with improved algorithms but requiring permanent storage of the largest files.

Clinical genomic data retention creates unique long-term storage obligations — variants of uncertain significance reclassified as pathogenic years after initial analysis require recontacting patients, necessitating data retention across the patient's lifetime that traditional short-term clinical data retention policies do not accommodate. The American College of Medical Genetics and Genomics recommends indefinite retention of raw genomic data from clinical testing, creating storage infrastructure obligations that healthcare organizations must plan for across multi-decade timescales.

Federated genomic data storage — enabling analysis of genomic datasets across multiple institutional repositories without centralizing the data — addresses privacy and data governance barriers to genomic research while enabling the large-scale analyses requiring sample sizes exceeding single-institution collections through collaborative computation that preserves data sovereignty.

Do you think cloud-based federated genomic storage platforms will enable population-scale precision medicine programs that single-institution genomic databases cannot support?

FAQ

How much storage does whole genome sequencing require? A single whole genome sequence requires thirty to one hundred gigabytes of raw data storage; clinical genomic programs sequencing thousands of patients annually require petabyte-scale storage infrastructure with appropriate security and long-term retention capabilities.

How long should genomic data be retained? ACMG recommends indefinite retention of clinical genomic data; long-term storage enables reanalysis as variant interpretation improves and allows reporting of reclassified variants to patients whose initial testing classified findings as uncertain significance.
