I have SSD as my C drives on all my computers with this Laptop being the only one without. That's why I really notice how slow it is to boot, I think it's even a 5400 RPM! And W7 is slow anyhow. You really do get used to W10 and an SSD and computers are up and working in a matter of seconds,, not minutes.
I ordered the Samsung Evo from new egg and just waiting it's arrival. I tried to clone the drive on my old DAW desktop to an older 220 GB laptop drive just to experiment but the Samsung app is only allows a Samsung as the new drive. So then I tried EaseUS and it didn't want to copy to the older drive re something about the different type of drive. GPT vs MBR
Just on a whim I thought I'd just Drag and drop the whole OS drive folders to this older drive... after 1 hour it's at 3% and it's only 45 GB total.. so Don't expect it will work. It was just a test so no biggy.
I'm just cleaning up the Laptops C drive and moving everything to a back up external as well as to the Data drive. The Data drive is only 220 GB I thought it was bigger.
