Thanks John, I bought this computer from Sears about 4 years ago and then I added the SSD drive myself(samsung ssd 850 evo 500 gb) about 2 years ago. I know now I did not set it properly. Yes, the comp does have the ahci option because with the technician over the phone we tried to change it but then the computer would not boot up so we changed it back to IDE. The reason I wanted to change it is because here are the performance records that I got when I ran Samsung magician: sequential: read 240 write 229 random: read 8056 write 15380. On the main page of Samsung magician it says the drive condition is good and the firm version is latest and the currently installed version is EMT02b6q then below that it says the interface is sata 3gb / s, ahci Mode deactivated, trim status enabled. Since the computer is kind of old and now it has been hacked, I was wondering if I should just buy a new computer because I do want to try the SSD drive at its full capacity so that my computer can run quickly. It's a business computer is not for games or anything but I would like to work as quickly as possible when I'm switching between programs. I watch a lot of YouTube videos and it appears that the speaker can switch screens and it's an instant switch where my computer has a 1 second or two second delay between switches. Can you recommend a reasonably priced desktop computer that already has the ssd drive installed and is set up for maximum speed. One last question, I understand that memory to make a lot of difference on speed also. What amount of memory do you recommend for max speed? Thanks again.
