I installed this in an acer aspire e 15 e5-575-33bm laptop. The computer came with a 1 tb hdd and 4 gb of memory, and was so slow it was basically unusable. Increasing the memory to 8 gb helped some, but replacing the hdd with this ssd made all the difference in the world. With the old drive, i'd turn the computer on, at which point i might as well go in the kitchen and make a sandwich - it might be ready to use when i returned. Opening any program was the same - an interminable wait until it loaded and could be used. With this ssd, boot up takes mere seconds and programs load in a few seconds as well. I've got an honest-to-goodness computer now!Installation was easy, just open the back of the case, slide out the old drive, and remove it from the drive caddy by taking out 4 tiny screws. Insert the new drive into the caddy, re-install the 4 screws, slide it into place and replace the back cover. I installed a new copy of windows 10 home, which came on a usb stick, so i just had the stick inserted into the usb port on the laptop when i turned it on for the first time with the new drive. Windows walked me through its usual installation procedure, i downloaded all the windows updates, installed my anti-virus software and other programs.Let me put it this way: this computer used to be so slow that it just sat on the table, unused. With this new ssd, everyone wants to use it because it's fast, and that makes it fun. If you're interested in productivity, this simply makes it skyrocket. No more frustrating waits, the computer just zips along wonderfully. I can't recommend this highly enough if you're suffering with a slow computer.
