Again we find when uploading a mixture of small and large files the performance of these devices is greatly diminished – more than halved, in most cases. The Synology DS2411+ was quite a bit slower than the DS1511+ in this test, but it still managed to exceed the results provided by the DS411+ and our Core 2 Duo test system. That trend remained identical in our program upload test: the DS2411+ (38MB/s) was much slower than the DS1511+ (50MB/s).
