Atto is a simple but effective file system benchmark. We run the test for three data lengths, 4MB, 8MB and 16MB. The larger data lengths are good for testing the maximum data transfer capability of the drive, while shorter lengths provide better real-world results. We can see that the maximum read rate of the Voyager GT is a whooping 32MB/s while the write rate is 25% lower, at 24.5MB/s. These are the best Atto results we ever received from a flash drive in Driver Heaven testing.

A well known all-around synthetic benchmark is Sandra. We ran two Sandra tests, the Removable storage test and the File System benchmark. The removable storage test gave us good results and a high endurance factor, although it seems that the Voyager GT faces a small weakness when dealing with smaller files. However it dominated the File System benchmark, giving results over 50% faster than any removable drive we could compare it with and a seek time lower than 1ms.

Real world read/write test, 700MB file
	Read	Write
700MB file copy	28.15 sec	34.56 sec
MB per second	24.86MB	20.25MB

In order to make our testing more complete, we timed the transfer of a 700MB file to the Voyager GT and then the transfer of the same 700MB file back to our HDD. As we expected, we received lower results for both the average read and write speed of the drive than the synthetic tests, yet very high results nonetheless. The Voyager GT can read nearly 25MB of data per second and store more than 20MB per second. That is 3 to 4 average sized MP3 songs per second, or 10 to 20 high resolution pictures. Extremely fast.
