Do i need usb 3.0 with 6 GB RAM?

I only have 20 gb's left on my gaming desk top. I would like to get a external hard drive to expand that, But im wondering if a external hard drive with 2.0 would work even though its slower since i have 6 GB of RAM. Would a USB 2.0 external HDD slow game play for me?

    the only way that an external hard drive would affect your game play is if you installed your game files to it. Just having an HDD plugged in to your computer won't really have a thing to do with the amount of RAM you have. The two issues don't have that much to do with each other. External hard drives connected with USB like that are generally intended for backup purposes, not for constant writing and reading. You can do that fine for a lot of applications, I don't know that I'd try installing a game to it. Consider that USB 2.0 is rated with a theoretical information throughput of 35MB/s (that's how fast it can theoretically transfer data) and SATA II (the kind of transfer that hard drives inside your computer use) is rated at about 300 MB/s. basically, if your computer is trying to read a lot of files quickly off a hard drive, you'd rather it be hooked up to something that can transfer data at 300, not 35.
  2. USB 2.0 would work, but it would be limited to 480 Mbit/s, which is similar to HHDs. So in short, you can but i'd suggest getting 1T HHD for the same price.
  3. 480 is the max theoretical throughput. Devices pretty much never operate at the maximum unfortunately.
