Did we really need to prove that expectations of ignorant people often don't correlate with reality? :D

Let's get back on track and gather some actual data from people who upgraded from USB 2.0 to USB 3.0 readers.

Realism in expectations is an important thing to set, not idealism!

My test system: i7-2600, 8 GB RAM, 7200rpm HD, Kingson USB 3.0 reader vs built in USB 2.0 reader, CDM 3.0.1 x64.

Lexar microSD 16GB class 10
22.54(18.23) - 12.37(10.13)

Adata SDhc 8GB class 6
22.66(19.52) - 17.01(13.29)

Adata CF 4GB 266x
45.99(32.89) - 28.31(22.64)

Transend CF 16GB 400x (spec as 60/30 R/W speed)
59.01(29.81) - 25.86(21.68)

I think for flash cards, we need true 266x or faster to take avantage of the USB 3.0 readers. The same slower card will write 10-20% faster on the USB 3.0 reader.

The normal USB 2.0 flash drive max out aroud 30/10 MB/s, where the newer USB 3.0 ones are 80/20-30.

What I really want the USB 3.0 is for external HD for back up. From what I read, the 3.0 is about 2 to 2.5 times faster than the 2.0 if the computer systems are up to date. I am still waiting for the HD price to drop though.

Okay, finally got around to doing this test. I used CrystalDiskMark 3.0.1 in 64-bit for both tests on the following spec'd computer:

Intel Core i7 2600K 3.4Ghz Quad Processor
Corsair H50 Hydro Series CPU Cooler
ASRock P67 Extreme4 B3 Motherboard
16GB DDR3 G.SKILL Ripjaws Series 1600 PC3-12800 Memory
2 x Western Digital Caviar Black 1TB SATA2 Hard Drives in RAID 1
BFG Tech 8800GTX Graphics Card
Audigy X-Fi Fatal1ty Pro Sound Card
Corsair TX 750W Power Supply
Dell U3011 30" LCD
Microsoft Windows 7 Pro SP1

The USB 2.0 test results are in Green, the USB 3.0 test results are in Blue.

The card was a Sandisk Extreme UDMA 32GB 60MB/s: LINK (external link)

The USB 2.0 Reader was a Sony: LINK (external link)

IMAGE: http://g-ecx.images-amazon.com/images/G/01/ciu/d2/3d/face228348a00a9edd8fe010.L.jpg

The USB 3.0 Reader was a Transcend: LINK (external link)
IMAGE: http://ecx.images-amazon.com/images/I/31zTXhrKl7L._AA300_.jpg

Both the readers were plugged directly into the motherboards USB 2.0 and 3.0 ports respectively and no major resource hogging applications were running.

The results were as follows:

OMG!!! I received my Transcend USB 3.0 reader and used it for the first time. The speed was UNBELIEVABLE! I don't have any measurable figures but it was significantly faster than firewire I've been using for years. Out of 200 raw pics to d/l out of 5Dii, normally I step away for a few minutes but this time I barely had time to grab a drink.

Great thread!! Best Xmas gift to myself EVER!! Thanks guys.

with SSD hard drives and USB 3.0 its really hard to go back to anything before. I never understood why it took so long to create a protocol that moves data quicker.

I get about 85MB/Sec with my 400x CF card which makes moving 32GB of data much more tolerable.

Totally agree. Just built a desktop with USB3 and SSD, insanely fast. So much better than anything previous.

ben_r_, your USB 2.0 results are awfully slow. Is the reader ok?

Download and run that benchmark program and post the results. I'm curious to see USB 3 vs FireWire.

Lol well, I like to keep spares of things around just in case, but yea, might as well be in the trash because now that I know how much faster USB 3 is I'll never go back to a USB 2 reader anyway.

You can also use a cable with a USB2.0 in a 3.0 slot.
My i5 computer has 4 x 3.0 and 6 x 2.0 usb connections. One of my outside drives is a iomega that has a cable with 2 usb 2.0 connection and that gives it also some extra speed. Believe me there are many possibilities.
