Ask HN: How would you store 10PB of data for your startup today?
At that kind of scale, S3 makes zero sense. You should definitely be rolling your own.10PB costs more than $210,000 per month at S3, or more than $12M after five years.RackMountPro offers a 4U server with 102 bays, similar to the BackBlaze servers, which fully configured with 12GB drives is around $11k total and stores 1.2 PB per server. (https://www.rackmountpro.com/product.php?pid=3154)That means that you could fit all 15TB (for erasure encoding with Minio) in less than two racks for around $150k up-front.Figure another $5k/mo for monthly opex as well (power, bandwidth, etc.)Instead of $12M spent after five years, you'd be at less than $500k, including traffic (also far cheaper than AWS.) Even if you got AWS to cut their price in half (good luck with that), you'd still be saving more than $5 million.Getting the data out of AWS won't be cheap, but check out the snowball options for that: https://aws.amazon.com/snowball/pricing/
