It would take an extremely large number of hard disk drives (HDDs) to produce even a small gold nugget or bar through the recycling process. Here's a rough estimate: Most HDDs contain only tiny amounts of gold, typically in the range of a few hundred micrograms to perhaps 1 gram at most for very large server-grade HDDs. To put that into perspective, a typical 3.5" desktop HDD may contain around 200-300 micrograms (0.0002 - 0.0003 grams) of gold. Now, let's consider recovering enough gold to make even a small 1 troy ounce (31.1 grams) gold nugget/bar: 1 troy ounce = 31.1 grams of gold If a typical HDD yields 0.0003 grams of gold Then it would take: 31.1 / 0.0003 = 103,667 HDDs to obtain 1 troy oz of gold So for a small 1 oz gold nugget or bar, you would need to process over 100,000 HDDs! For your suggested number of 500,000 HDDs, and assuming the same 0.0003 grams of gold per drive, the maximum amount of gold that could theoretically be recovered is: 500,000 HDDs x 0.0003 grams/HDD = 150 grams of gold This amount would produce a gold bar or nugget weighing around 4.8 troy ounces. Of course, these are rough estimates, and actual gold yields can vary based on HDD models, manufacturing years, and the efficiency of the recycling process. But it highlights how many HDDs are required to accumulate even modest amounts of gold through urban mining of e-waste.

500 000 Hard Disk !!!! you accumulated those disk over time ? or do you get them over time ?
