Team Group advertises the performance with 15 MB/s read and 5 MB/s write speed at most. So we were positively surprised to see read speeds closer to 20 MB/s. Sure, there are USB flash drives out there which are much faster, the Diamond aims to combine a small form factor with an affordable price tag. On the latency front, the Diamond manages to impress with a mere 0.4 ms.
ATTO delivers the same read results as HD Tach, but also reveals a maximum write speed of 7.5 MB/s which is once again more than what Team Group advertises.
