Noticed after replacing 2032 battery on a board and reconfiguring the bios settings that the SATA controller was set to IDE. When looking at the choices its AHCI or IDE with IDE being the default config. I left it at IDE but was wondering that other than what I see here about the 2
http://www.diffen.com/difference/AHCI_vs_IDE are there any pros or cons to leaving it alone at IDE. The hard drive is an older laptop hard drive that is 1.5 SATA and not 3.0 speed and only 5400rpm. I cant imagine there being that much of a performance gain in switching to AHCI. The motherboard runs an Intel Atom D510. I pretty much repurposed a laptop hard drive for this ITX build and knowing that the Intel Atom was going to be not the best of performance anyways that a slow older hard drive paired with it would probably be just fine.
Performance wise, the build is reliable and works well for what it does. Just figured I'd check here to see if its worth it at all to switch to AHCI vs leaving it at IDE default for the SATA controller setting. To me it seems that maybe if I had an SSD that this AHCI would be beneficial, but still the Atom CPU is a bottleneck in the performance of a SSD as well so idk.
