I currently have a 1TB 5400RPM HDD in my laptop that I want to swap out for a 256GB SSD (preferably a Crucial MX500) - 512GB SSDs are a bit too expensive in my country, and I don't have a big enough budget. As 256GB isn't too large, I thought I'd repurpose my old HDD as an external one and play games off of that. My question is, how badly would this affect performance compared to an internal HDD? (I know this isn't an ideal solution but I can't get a bigger SSD).
