I have two Flash Drives of the same brand and model. For some reason transfer and read speed is different. Meaning one faster than the other in speeds. Does it means one of the drives could be defective?.
Plug one in at a time, then go into Disk Management > Right click on the Removable Drive (Your UFD) > Properties > Details (Tab). Pull down the Property drop down box and select Hardware IDs. Compare to make sure that both UFDs are in fact the same.
From the looks of it. Ids are the same. Unless i am missing something.

Yeah, they look the same. I thought that would be an obvious reason, but it must be something else. And I am sure you would be testing both of them with the same USB ports. Your original assumption must be correct. Is there a noticeably big difference in performance?
Hm. I have found some info here. http://driverlibs.com/download/UFD-3.0-Silicon_-_Power32G-USB-Device Seems like there are updates for those drives or more like firmware updates.
Does the slower of the 2 drives still meet the manufacturer's specification for read and write speeds?
What brand flash drives? What is the maximum read/write speed of each drive? You can use Atto... http://www.majorgeeks.com/files/details/atto_disk_benchmark.html
Strange , but I had a similar experience with two identical Kingston " Data-Traveler " flash drives. Both bought from the same batch , same store at the same time , but one had somebody's music collection on it ! Both in original sealed factory packages ..... I contacted the maker but never did find out how or why .
Did you get these at Fry's? This is something Fry's electronics is famous for, repackaging returns & selling them as new. @OP Are they the same file formats & cluster sizes?
No , I have never heard of Fry's , but what you describe seems a very feasible explanation for what I experienced . I was away from my home country at the time , so I have no idea if the computer store I visited was an independent , or part of a national chain.
sounds like all your usb ports are the same. when I went with macrium reflect I got a sandisk ultra usb 3.0 and really like it so far. I remember my first geek squad usb stick was a whooping 1 gig for 99 bucks lol
you must have got your 5 years after me lol can't remember how much I paid the one mentioned above but it is a 256 gig and was probly 55 bucks.
I ditched all the UFDs less than 512MB in capacity, and kept about 20 of UFDs varying from 1GB-16GB. I got most of them for free (after rebate).
