Anyway, someone was asking why you'd ever want to defragment an SSD? Good question, I think. Two things:
1. Sequential access is still faster with SSDs, just not by a margin of infinity anymore. I guess this is because of prefetching in the controller of the drive itself?
2. To reduce bookkeeping overhead? You need less space to store the information "blocks 1-3" than "block 1, block 17, and block 59." I have no idea how NTFS works or anything, this is just a guess.
- 0xdeadb00f 6y agoI thought that defragging an SSD was bad because it exposes it to more reads/writes than necessary, and since SSDs are less resistant/have less tolerance to excessive read/writes it could shorten it's lifespan (probably not by a great or noticeable amount in the grand scheme of things, however).
- boring_twenties 6y agoIt's certainly bad to do it every day, hence the fix described in the article. But mightn't it make sense to still do it occasionally?
