There is one upgrade that will universally improve a laptop’s performance: adding an SSD. This is a particularly attractive upgrade for budget laptops, which typically come with a hard drive. That’s the case with the extremely popular Acer Aspire E 15.
This laptop has been the top seller on Amazon for months and months. It’s easy to see why: for $350 (and below $300 during the holidays), you get a 7th-gen Core i3 processor, 4GB of DDR4 RAM, a 1TB hard drive, and a 15-inch 1080p screen. It’s a killer deal for those on a budget—but not exactly fast.
