It's on USB so it's not that fast. If your model has only the SSHD you can gain some performance by changing that to SSD. The old SSHD can be repurposed to external for backups.
Hey, I just got a new laptop - ASUS TUF Gaming FX504GE-E4423T. I want to buy an external SSD for an upgrade. Will it increase the performance at least a bit? (the laptop has Intel Optane already). Do I just buy an SSD and connect it to the laptop through the USB ports or does the laptop have a place for upgrades underneath? Thanks.
