Appunto...anche se la loro logica è diversa dalla nostra.
Brian Wilson, CTO and founder of Backblaze (he shares a name with the 71-year-old Beach Boys front man - though we do not think they are one and the same) explains it this way:
Double the reliability is only worth 1/10th of 1 percent cost increase. I posted this in a different forum:
Replacing one drive takes about 15 minutes of work. If we have 30,000 drives and 2 percent fail, it takes 150 hours to replace those. In other words, one employee for one month of 8 hour days. Getting the failure rate down to 1 percent means you save 2 weeks of employee salary - maybe $5,000 total? The 30,000 drives costs you $4m.
The $5k/$4m means the Hitachis are worth 1/10th of 1 per cent higher cost to us. ACTUALLY we pay even more than that for them, but not more than a few dollars per drive (maybe 2 or 3 percent more).
Moral of the story: design for failure and buy the cheapest components you can. :-)
