The FileMate SolidGo Ultra is a great product. Data rates are as high as promised and I didn't find any other product as good as this one for a better price.
The ExpressCard does get quite hot - as I read in other reviews - but it didn't cause any harm after 5 weeks.
However, I encountered a driver problem when using the SolidGo in the ExpressCard slot. It worked flawlessly in a Studio XPS 16 with Win 7 Professional, but on an Inspiron 9400 running Win 7 Ultimate, file transfers larger than some tens of MB to and from the SolidGo slowed down significantly. Copying files of GB size was impossible, transfer speed slowing down to zero, at which point canceling no longer worked. Updating chipset, JMicron drivers etc. didn't work. Disabling SolidGo's writing cache, which is enabled by default in the device manager, made copying files a bit slower (~50 MB/s writing speed), but finally the card worked without problems.
