Hard drive speed is 7600 udma but it actualy only can run at 6200 or something cuz of my bios. Cannot upgrade that cuz its a wonky pc chips chip .. that is one thing that I do know...I am reluctant to get more memory just yet cuz I got a feeling my motherboard will take the memory that I would have on a newer pc...
But if like the drive it would work but just not at its optimum perforfmance then I would for sure invest in memory
