I rescued an old Dell laptop from a junk pile and my 7 year old has been using it. It was painfully slow and I found it unusable. Remembered I had a spare SSD, cloned the disk and stuck it in, it is like a new laptop. Absolutely flying.Massive mate, some users machines without SSD took like a minute to boot up and to login.
With the same amount of data on the machine and Windows 10 with an SSD takes like 5 seconds to boot up.
Even had some users took like 5 minutes they said they would login go makes coffee come back and still wasn't on desktop screen
