VMware: Defrag or Not? Dave Lewis sent in a question, “There is such a quandary about disk fragmentation in the VMware environment. One says defrag and another says never. Who's right? This has been a hard subject to track and define.” I’m going to debunk [...]
After having chatted with 50+ customers the last three months, I’ve heard the same five questions enough times to turn it into a blog entry, and a lot of it has to do with flash: 1. Do Condusiv products still “defrag” like in the old [...]

The purpose of this blog post is to provide some data about fragmentation on the Mac, that I've not seen researched/published elsewhere. Mac OSX has a defragmenter in the file system itself. Given Mac is open-source, we looked at the code. During a file open the files [...]
