Re: [DIYbio] exome and genome data storage

Yours seems correct. The only thing I would use would be error correction code (in RAM and/or in disk writing)/redundant sectors/RAID, but even that wouldn't be more than 40GB. I'm wrong or missing something too. This link has a curious number: http://www.kinexus.ca/pdf/graphs_charts/HumanGenomeSequence.pdf

Are you sure you're not thinking before assembly vs after assembly? If humans are around 6.5 gigabases, and 2 bits per base, that's 1.625 gigabytes. Assuming we just use one byte per base, that gives us 6 extra bits for storing methylation status, etc, and is 13 gigabytes (also what it costs to store that as ASCII). 

Am I missing something?

By one estimates, I read that the costs for storing full genome sequence data would be pricey (50 terabytes), although I read this article about a new optical disc that may be released in 2015 which will store 1-15 terabytes of capacity. I'm not sure what media formats genomic sequencing services use, but blu-ray discs costs about about $1/BD-R and make exome data storage relatively affordable. It's not unlikely that the price of TB optical discs will cost $4-5 dollars in 2018. A full genome sequence would likely benefit from something like the above link, because 4TB hard-drives aren't inexpensive or lightweight.
