1 "And SSDs have a finite lifespan under constant write load."

Years ago, someone, maybe at Anandtech, but I don't remember who for sure, did some long-term tests and discovered that a lot of SSDs, while they were rated for something like 100TBW per TB of capacity, actually didn't start failing until more like a couple of petabytes written per TB of capacity.  I don't think anyone's publicly done anything like that recently, though, and the Tom's article did mention that TLC drives are less susceptible than QLC drives.  But it's still a bad design.

Also, the article "explained" that it's something to do with some database, but devolved into gibberish Treknobabble for a paragraph or so, which was really lame.

2 RocksDB uses what is called a log-structured merge tree, which allows it to perform very fast updates by writing random updates as a sequential log before merging the table data together.  That was a big deal before SSDs, it's not so significant now.

But the real reason Windrose uses so much disk bandwidth is that the developers are idiots...  In this particular field.  There's no reason for it to write that much.

Apple pies are delicious. But never mind apple pies. What colour is a green orange?
