[Year 12 SofDev] SSD vs HDD in data centres

[Mark]

This ancient article (from 2012) is rather interesting.

It asks: how can data centres actually save money by using low-capacity,
expensive SSDs in place of big and cheap HDDs.

"One SSD, ... can handle about 40,000 reads or writes a second, whereas the
average hardware gives you about 180. And it runs at about one watt as
opposed to 15 watts, which means you spend far less on power. ...
In short, you need fewer servers to do the same amount of work.
At Wikia, Bergman first installed SSDs on the company’s caching servers,
used for providing quick access to data that repeatedly accessed by web
surfers. Then, he moved them into the company’s database servers, where
data stored more permanently. This provided so much additional speed,
Bergman says, the caching servers were no longer needed."
