File Testing

hdtune-file

Benchmark Results: The file benchmark results look good with greater than 100 MB/s writes for most file sizes over 16KB. Our real world testing and file backups bounced around a bit, but for the most part were between 75-100MB/s. The drive also felt warm to the touch during use, but never got much hotter than 31-32C during use.

    I used the hard drive GripIT an anti-slip cooling grip pad on the bottom on my drives. It has an extreme grip up a 45 degrees angle and works on all surfaces!
