One of the most common operations performed on a PC is moving/copying files. Using a free application called Teracopy, we copied large numbers of two file types from one folder to another on the same drive. Teracopy allows us to objectively measure the time of transfer and using the same drive prevents other devices from tainting the outcome. The operation requires the drive to perform both sustained read and writes simultaneously. The first set of files is a 5GB collection of JPG’s of variable size and compression levels with a few movie (.MOV) files thrown in for good measure since most cameras now take video as well as stills. The second is a collection of MP3 files of various sizes which totals 5GB collectively. These file types were chosen due to their wide use and mixture of file sizes and compression levels.
Install Results: With times that are in the top third of the comparison, it was interesting that the JPG copy time was a fair bit off of the MP3 copy times – moreso than we’ve seen with most drives. We ran this a number of times and the result was always the same with little variation. We saw this with the Kingston HyperX 3K drive as well so it’s not unprecedented although we can’t point to the root cause of the anomaly but it maybe firmware related.
Windows start up/shutdown time is always something people are interested in and we haven’t done it in a while because there was little variation with the majority of the SSDs. We recently began using an application called BootRacer to objectively measure the startup times of the drives. All of the instances of Windows were identical and freshly installed with only the video driver installed.
Test Results: The SX900 was one second faster in time until login than most of the drives we’ve tested with the time until desktop being at the average.
We’ll wrap this with a look at the total drive capacity, TRIM performance and our final thoughts.
