When ReadyBoost first came out for Windows it was a big deal, but it's rarely mentioned or discussed these days.
Even though the average Windows computer now likely comes with 8GB of RAM, the size of many applications has increased tremendously. For example, web browsers like Firefox, Chrome, and Opera can easily occupy 4-6GB of RAM on their own when a bunch of tabs are open (especially when extensions/add-ons are installed).
Also, not all computers have that much RAM. Many budget computers are still sold with 4-6GB of RAM.
Are there any downsides to using ReadyBoost in Windows 7-10?
