Last month I bought a Patriot Tab 16GB (PSF16GTAB3USB) from computeruniverse.net. Data transfer rate was given as 140MB/s reading and 70MB/s writing, the stick is a USB3.0 one.
During testing, I discovered that the write rate was a mere 8.3 MiB/s, a thenth of the promoted rate.
I asked the Patriot support for their transfer rate claims:
What is the minimum transfer rate I will get?
They responded quickly with following e-mail:
So their official maximum write rate is 17MB/s, the minimum 11MB/s.
Don't buy it.
