Testing (continued):

Real World File Transfers - Large Files:

In the first phase of performance 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 DS414Slim, we see a transfer rate of over just over 100MB/s, which puts it near the top of the NAS servers tested.



Writing the large file to the DS414Slim was not as impressive, here we saw just over 50MB/s. While this was the worst performer in this category, it isn’t too far off some of the larger units.
