If you bought your iMac 3-5 years ago, there’s probably nothing so seriously wrong with the hardware that you need to consider replacing the machine. Sure, the new iMac with 5K Retina Display looks a little nicer, but at a steep $2,499 starting point, it’s still a luxury, not a necessity.
Yet there’s something you can do for $200 to $500 that will radically change your iMac’s performance: install a solid state drive (SSD) in addition to or instead of its original hard drive. SSDs use high-speed memory chips rather than the spinning platter mechanisms in traditional hard drives, achieving up to 5X benefits in speed while requiring no moving parts. Five years ago, SSDs were both expensive and limited in capacity, making them unlikely components for most Macs. Today, high-quality, capacious SSDs can be had for reasonable prices, and they’re surprisingly easy to install in iMacs. With limited expertise and only three tools, I swapped out my old hard drive for an SSD in roughly 30 minutes. Here’s how I did it, and – if you’re up for a quick do-it-yourself project – what I’d recommend for you.
