Because idiots guess that it's useful to decrease the write cycles, to increase the lifespan of SSDs? I migrated to SSDs only internal my tower desktop PC and just use external HDDs for backups. However, I treat my internal SSDs the same way as I treated my internal HDDs. I want to use my computer as a tool, without warpping any part of it in cotton wool. It already is bad enough, that I can't handle my LCD that rough as I could handl my CRTs. Don't watch too long at your LCD screen, since it could cause visable scratches. Sorry, actually I need to take a look very often and very long on my LCD screen and I also want to use any file system with or without journaling and any kind of work-flow when using a SSD. The only compromise I'm willng to do is cleaning my LCD display at full moon nights only, with microfibre cloth and destilated water only, instead of using the sandblaster I could use withou any side effects to clean my CRTs at any daytime and at half moon as well as full moon.
