TeraCopy is a compact program designed to copy and move files at the maximum possible speed and features a timer that works great for review purposes as we can easily show you time differences between different file transfer scenarios. TeraCopy also uses dynamically adjusted buffers to reduce seek times and has asynchronous copy speeds for file transfer between two physical hard drives.
First, I did a mass upload to the N5500 of 42 files of various sizes and types with a total overall size of 4.89GB. The upload from the PC to the N5500 NAS only took 1 minute, 36 seconds at 52MB/s.
I then downloaded those same files from the N5500 to a folder on the desktop. It took 1 minute, 55 seconds at 43MB/s.
Next, I uploaded a single large file consisting of a DVD ISO totaling 4.36GB. The upload took 1 minute, 25 seconds at 52MB/s.
Again, I then downloaded the same file from the N5500 to the desktop. The download took 1 minute, 40 seconds at 44MB/s.
