Amazon is offering the Buffalo Technology MiniStation 500GB USB 2.0 external hard drive for $40 with free shipping. That’s $10 below the next lowest price and $30 under the average street price. While it does not support USB 3.0, we don’t think that’s a huge deal as this drive is still perfect for someone looking for a smaller drive to perform casual backups. Even better, the MiniStation has a futuristic blue activity LED. Compatible with Mac / PC and does not require an external power source.
