Good day, fgmedv100 the HP Lapi already has a 256 GB SSD. Another SATA port is not available in the device.
You can easily change the built-in SSD to a 500 GB SSD, for example. TIP: No SAMSUNG, they currently have problems with performance. OZC, Kingston etc. Replacing is possible with effort, you have to replace the hard disk under the keyboard. Before that, a CLONE with Acronis and then everything is available on the new large SSD as usual. (
