How's the performance of installing Steam games to an external USB 3.0 HDD??

If its a true USB 3 device, I imagine it wouldn't be much of a bottleneck at all as most games would need sustained read, not necessarily random seek performance. Let us know how it goes. I can't imagine it would be much worse than an internal drive.

It's one of those, says it's 3.0, not sure what "true" 3.0 means but yea.


I say 'true' because there are quite a few products out there that boast USB 3.0 compatibility as a feature rather than its bandwidth capability. All USB devices work with USB 3.0 ports so its a bit of a joke at times. HDD enclosures shouldn't be a problem these days though.

It's unlikely that the game will be writing to the disk so enabling the write caching isn't going to impact the read performance.

It tends to add more read caching as well when it's enabled.
With it disabled, prefetch isn't enabled on the drive (unless this has changed since windows XP)

My USB 3.0 drive is almost as fast as my internal drive, so it's really no different at all. But as others have said, you have to disable the quick removal features for the best performance.

Why don't you just use the external to back up games you aren't playing currently. Then you can uninstall those games to make more room on your internal drive for the ones you are. When you want to play one of the previously backed up games, just restore it so you can install it without having to download again.
