The new Adata Dashdrive UV128 has a performance profile that closely matches its older, and recently rebranded, Dashdrive Elite S102 Pro sibling. Comparing the two shows that the drives are nearly identical except for form factor. Personally I prefer a retractable form factor as USB caps are easily lost. Overall in terms of performance the Dashdrive UV128 is slightly above average and in terms of value for money it is also reasonable. [Jul '13 USBFlashPro]
