Testing (continued):

Real World File Transfers - Large Files:

In the next phase of testing we will look at transfer speeds during real world file transfers. For all tests, the files described were transferred to/from the Windows desktop PC and one of the storage servers while a stopwatch was used to record the duration. Then the file size and the transfer time were used to calculate a transfer rate.

Large file transfer rates were the first area of interest in this part of testing. Disk images, HD video files, and large multimedia projects would fit in to this grouping. The large file transfer test involved moving a single 5.96GB (6103MB) MPG video file around the network to the storage servers of interest. A reboot of the Windows desktop system was executed between each test, and different folders were used for reading and writing.

When reading the large file from the DS415play, we see a transfer rate of 103.44MB/s, which is easily the fastest of the four devices being compared.



Writing the large file to the DS415play was definitely quick, and the resulting transfer rate is very impressive. 101MB/s is quick, and far above what the other two NAS servers were capable of.
