I'm copying a large (10GB) file from my Intel 520 SSD to my Patriot USB 3.0 flash drive. It's advertised as getting 150 MB/s, but I'm only getting around 23 MB/s. Any idea where I'd start to look for the culprit here?
Did you do any standalone benchmarks? What model flashdrive? I've seen a few USB 3 drives with high read speeds but then write speeds are just average. That is unless the 150MB/s number is it's rated write speed.
