  • Slow, but massive

    If you need an external mass storage drive, I'd certainly recommend this behemoth. I primarily use this as a backup drive, and a storage drive for my Steam game collection. Now that Cox data-capped my connection, I just transfer game data over to my ssd instead of re-downloading. This drive is slow however, operating at 5400rpm, so large file transfers can take a minute. I didn't really factor that into my rating as I would hope that people aren't playing games on external/slow hdd's when the cost of solid state memory has dropped so far.

    I am now able to move documents or videos that I don’t look at anymore and put them on the hard drive. Now my air mac has room again and is working great! If I decide I need something on their I must open it up and move it back to my computer. I keep my relatives who have passed on my commuter but store them in the external drive too. That way if something happens I will always have them.
