I have a Dell E1405 laptop from 2006 that I was thinking about upgrading. It doesn't support AHCI. Given that, would I still see a significant real-world performance jump going from the stock 5400 RPM SATA drive to a new SSD? I've done a few searches and found conflicting results. I did see this article: http://benchmarkreviews.com/index.p...sk=view&id=505&Itemid=38&limit=1&limitstart=3 which shows that for the Seq and 4K read/write tests, the difference between AHCI and IDE is not substantial. On the other hand, the 4K-64Thrd benchmark shows a huge improvement between AHCI and IDE. I suppose the question is: how well does the 4K-64Thrd benchmark reflect a real world scenario of typical home PC tasks: office work, web browsing, media player, copying files, etc.? Should I go with an SSD, or save some money and just get a new 7200 RPM SATA drive?
