Concluding remarks
We had three primary questions in mind when testing these USB 3.0 and USB 2.0 drives. First, how much faster are the USB 3.0 drives than USB 2.0 drives when each is plugged into their respective native port? The benchmarks and real-world scenarios clearly illustrate that USB 3.0 is faster across the board, sometimes by nearly 900%. Second, are USB 3.0 drives faster than USB 2.0 drives when both are plugged into a USB 2.0 port? Though USB 3.0 support is increasingly common on computer systems, USB 2.0 will remain more common and often the only choice for years to come. Our testing indicates that using a USB 3.0 flash drive in a USB 2.0 port yields better results than sticking with a USB 2.0 flash drive. Third, are USB 2.0 flash drives faster when plugged into USB 3.0 ports compared to USB 2.0 ports? Yes, but not by much at all—you'd likely not even notice the difference.
Are USB 3.0 flash drives worth the increased cost compared to USB 2.0 flash drives? We’ve provided performance data, and pricing is always variable depending on sales, rebates, clearances, etc. You might also want to consider how often you lose flash drives! (And how impatient you become watching transfers progress!) Given my personal USB flash drive usage patterns (occasional backups and data transfers), I think the Mushkin Ventura Pro, Kingston DT Ultimate, and Patriot Supersonic USB 3.0 flash drives are particularly appealing. These three strike a good balance between price and performance given today's prices. If you tend to write files rarely and read them frequently, the least expensive USB 3.0 flash drives provide substantially faster reads than USB 2.0 flash drives. However, if you use flash drives more often, such as frequently throughout the day, you’ll want to consider springing for high-performance models like the Patriot Supersonic Magnum and Super Talent RC8.
Finally, we’d like to thank the manufacturers for supplying flash drives for this roundup. We appreciate the samples sent from Patriot, Kingston, AData, Super Talent and Mushkin!

Are you talking about 6GB/s eSATA III?USB3 is so much faster than the last eSATA, I'd be surprised to hear it's "protocol overhead" could make it perform slower.

I have the ADATA S102, got it a few months ago. So far I've been very happy with it. At home where I have a USB 3.0 controller card and an SSD boot drive, copies to and from the ADATA are screaming fast. At work, even on USB 2.0 it's still pretty fastPotablePots - Friday, July 29, 2011 - link
I was actually hoping that this article would look at portable application performance. I use a ton of portable application software and finding a flash drive that will give the best performance when running applications is something I could use AT's help on. Most of my portable software comes from PortableApps.com. I use mostly Portable Chrome and OpenOffice but also GIMP and Blender on occasion.Aikouka - Friday, July 29, 2011 - link
Zach, is it possible that you can list some value to help identify how much data you're transferring to these devices in the real world tests? For example, while I may copy PDFs to my thumb drives at times, I don't necessarily copy over hundreds of megabytes worth. I normally spend the most time waiting when I'm copying really large files to a thumb drive such as a movie I shot on my HD camcorder.Gigantopithecus - Saturday, July 30, 2011 - link
Hi Aikouka - The details of the real world scenario tests are on the second page. For the PDFs, the test copied 3,364 PDFs totaling 3.20GB. As I said, there are as many real-world usage scenarios as there are flash drive users! I personally, on a near daily basis, will copy hundreds, if not thousands, of PDFs onto a flash drive to perform a dump on a colleague's computer (hmm, that doesn't sound good - but you know what I mean, ha). That is if someone asks me about topics x, y, and z, I'll simply say read these, and give them a bunch of articles. I addressed your interest in large file transfers with the 100MB Iometer benchmark numbers and the real-world DVD ISO file read/write performance times. Those should give you a clear picture of which drives read and write bigger files, like those shot on your HD cam, the fastest.justcommenting - Friday, July 29, 2011 - link
Hey,I don't mean any offense, but I thought the writing style with this post was below normal Anandtech standards. The introduction skips details on what USB 1.1 changed that saw the widespread adoption and jumps around between discussing USB flash devices and USB hard disk devices without distinction between the two.
I appreciate the various graphs, but I don't think the author did a very good job of explaining why certain drives pulled ahead in various scenarios, why that might matter, etc. Instead, graphs felt tossed into pages with little more than a description of the picture underneath.
Like the pages before it, the conclusion is also a tough read due to general poor sentence / paragraph structure. I love Anandtech articles because of the highly technical content and the well-phrased, well-researched, and well-backed opinions put forth. I'd pay for it if I could, but preferably with stronger articles than this one. :)

indeed and less exclamation marks would be a start :)still, very interesting article

Nice random U-M reference.Ah, the VERY long nights spent there. Although I preferred the Media Union.

I hoped someone would catch that. ;) Lotta really long nights there, brother!Goi - Sunday, July 31, 2011 - link
I would've liked to see what controllers and NAND flash chips were being used in the different flash drives. I know some are using USB 3.0<->NAND flash bridge controllers, while others are using SSD controllers with a separate SATA<->NAND flash bridge, or perhaps using a NAND device with a SATA interface. It would be interesting to find out how these design decisions affect performance.
