I bought a laptop and unscrewed it once. Now there's such an empty space. Is that for another ssd? So I can build in an ssd and is the plug there a connection for an ssd?
Looks for a normal SATA connection
I.e. You can connect a SATA SSD or hard drive in 2.5 "format there
Yes, I think it's a SATA (SSD) slot.
Yes should fit
