Transfer speed of flash drives seems to vary significantly. What do people see as the minimum acceptable performance (read / write in MB/sec)? What would constitute really good performance?

Jeff Atwood wrote a nice post on Coding Horror about large USB flash drive performances. I recommend you read the full article. Below is an excerpt:
Modern 2.5" hard drive performance looks something like this:
HDD Sequential Read 55 MB/sec HDD Sequential Write 55 MB/sec
But what about large USB flash drives? How do they compare to typical hard drive speeds, much less the awe-inspiring Velociraptor? X-Bit Labs recently reviewed three 32 GB USB flash drives:
Type - Sequential Read - Sequential Write
32 GB Corsair Flash Voyager - 22 MB/sec - 10 MB/sec
32 GB OCZ Rally 2 - 30 MB/sec - 22 MB/sec
32 GB Patriot Xporter XT - 31 MB/sec - 17 MB/sec

This doesn't answer the question of what people see as minimum acceptable performance, but there are some good charts at tom's hardware.
It does allow you to gauge what might be seen as top end and bottom end though. It seems if you're not getting at least 20/10 then you're being short changed. – Jon Hopkins – 2011-01-14T09:55:26.250
Would also love an answer to this. – Hashim – 2017-10-07T20:07:10.637
