The HP Envy TouchSmart 4 had the lowest performing USB 2.0 implementation as far as read speeds are concerned. It managed just 27.7MB/s. It appears that HP's implementation is always a problem as the HP Folio 13 we reviewed last year is the second slowest system in our chart.
The TouchSmart 4 redeems itself a bit when it comes to USB 2.0 write speed. It manages to beat out the older Folio 13 as well as the GIGABYTE U2442F with an average of 21MB/s.
As far as USB 3.0 performance goes, the TouchSmart 4 is roughly in the middle of the pack. USB 3.0 read speeds are a close spread.
The trend continues with USB 3.0 write speeds. The TouchSmart 4 hangs with the faster machines, but does start to fall behind the majority of the pack.
