Sure enough, you can—but just keep in mind that those external drives almost always use slower disks (usually 5400 rpm), and you’re essentially paying an extra premium just for the enclosure itself.
If your main goal is simply to get a drive for a PS3 or a laptop, I’d suggest just buying a bare 2.5" internal drive instead—you could opt for a faster 7200 rpm model, or if you stick with 5400 rpm, it'll likely be a bit easier on your wallet.
For instance: Seagate Backup Plus Slim 320GB at 5400 rpm comes $123 as an external unit, whereas a standalone Seagate BarraCuda 500GB at that same 5400 rpm speed would cost $110.
Alternatively, a Seagate FireCuda 320GB which features a 7200 rpm spindle and a 16 MB cache would run at $137 (just the drive itself), though it'll definitely be snappier than the other options mentioned.
Now, if what you actually meant was buying an external drive just to swap out whatever is currently in your PS3 or laptop—or perhaps putting your old internal drive into an external case to repurpose it—then you'll need to hunt for an external drive where the housing isn't a nightmare to open without breaking it. In my experience, that isn't exactly a walk in the park with something like the Seagate Backup Plus Slim 500GB we discussed earlier... (plus, you'll void your warranty the second you crack that shell open).
In that specific scenario, your best bet is probably just buying a bare drive and a separate external enclosure.🙂
