Once unthinkably huge 2TB and 4TB SSDs are now commonly available, too, albeit at eye-watering prices. Replacing your old 500GB hard drive with a same-sized SSD from a reputable manufacturer costs only $150, while 1TB drives are under $330, each $100 less than only a couple of years ago. Today, high-capacity SSDs are more affordable than ever. All for much less than the price of a new Mac. Replacing a Mac’s 500GB or 1TB hard drive with a same-sized SSD required at least $250 back then, but the benefits were tremendous: even an aging machine became markedly (5x) faster, silent, and - unexpectedly - more fun to use. When I first wrote about using solid state drives (SSDs) to radically improve the performance of older Macs, high-capacity SSDs were just beginning to become affordable.
