Apple I bought a brand new iMac on Tuesday. I'm pretty sure this will come as a surprise to some, so I figured I might as well offer some background information about this choice - maybe it'll help other people who are also pondering what to buy as their next computer.

Well, two things. First, I'm not sure I can believe that "10 years" figure; I've done some reading about SSDs, and it doesn't seem totally believable to me. Not for a system drive with swap and all your data, at least. It just sounds too far-fetched. Maybe in a perfect world and in perfect conditions, but not in this world.

And second, SSDs definitely have the theoretical edge over hard drives when it comes to the speed of reading files that are laid out non-contiguously on the drive. But... at the same time, in all my time running Linux (exclusively for about 6 years), I have not had any major slowdowns due to fragmentation. It just doesn't happen. I was leery about moving entirely to an OS that doesn't even offer a native defragmentation program, but it turns out that it really is needed much less.

On the other hand, before I switched I was using Windows XP, and it seemed like I was running PerfectDisk every week or two just to keep the drive running at peak speed (especially the system drive). So... I guess the moral of the story here is that Windows users have more to gain in terms of performance than Linux users by using an SSD?

I recently found out about the free version of PerfectDisk and had my cousin install it on his Windows 7-based machine... as I expected, just one offline/boot defrag and one online defrag made a very noticeable performance improvement. So apparently on Windows a good defragging is still needed. [Note: Previously, I told him to install the free program Defraggler, which he used until then. IMO, PerfectDisk is a must... if I ran Windows today, I would no doubt buy another license for a recent version of the program.]
