iMac Hard Drives & Mac mini SSDs
Speaking of iMacs and Mac minis, Apple offers a range of customization options for those computers. Some of them you shouldn’t take, especially at this point. An example? iMacs with an ATA or Fusion Drive.
Those drives aren’t SSDs, which means that your data performance is going to be a lot lower. Opt for an SSD instead. If you need more storage, you can always get an external SSD, too.
Similarly, you should avoid buying too much RAM on your 27-inch iMacs or Mac minis. Why? Because you can actually just buy off-the-shelf memory and install it in your computer yourself. That’ll save you some cash in the long run and doesn’t take much technical know-how at all. Stick with the base RAM and upgrade later. (This advice doesn’t apply to the 21-inch iMac, which doesn’t have user-upgradeable memory.)
