Dell Latitude E6230 boot with SAMSUNG 830 Series MZ-7PC128D 128GB SSD
Some serious difference after upgrading hard drive and fresh Windows 10 installation, samsung 128GB ssd was used.
I received this 13.3" Dell Latitude E6230 with standard 500GB Western Digital hard drive witch was not bad either but laptop was functioning with very average speed for 3rg generation Intel i5 processor so i changed hard drive for SAMSUNG 830 Series MZ-7PC128D 128GB SSD and boot speed and general operating improved seriously.
Personally i hate using device where you see loading icon everywhere because its just not fast enough and even simple explorer windows will take 3-5 seconds to open.
Definitely best and most beneficial upgrade you can have on your device is SSD drive. See video:
