Is it possible that I can install a portable SSD hard drive in my laptop, you can't remove it from the case as with the larger ones is approx. 5 cm tall. And has USB 3.0
This can't be removed from the case, and it also has no E-Sata connections, only a smaller USB connection. If you expand it.
You can expand it

These hard disks are usually built into a housing and can also be removed. You just have to take a closer look at it.
That's a portable SSD. So you can't expand that. Like a bigger one… It's like a slightly larger USB stick. Because my USB port has so loose contact. I have a 128 GB SSD in my laptop. But 500 GB current outside. Can you also connect to USB mini. In the laptop?
