Don't know about any good but I am using two of them (PNY Performance) that I bought just before Christmas.
The first is a speed test on a sandisk ultra usb 3.0 (9.99UKP at PCW), then followed with 3 tests at writing a 100MB, 10MB, then a 100MB file. This isn't a full test with a disk benchmark, but seems reasonable.
