USB flash memory drives are now part of our lives. Smaller and with a capacity higher than floppy disks, these devices are the perfect replacement for the old floppies. This time we brought four new models from Patriot (Xporter XT), ATP (ToughDrive), Corsair (Flash Readout) and OCZ (Roadster) and added them to our previous roundup, so we are comparing 13 different USB flash drives. Who is the winner?

Here is the full list of the USB flash drives we included in this roundup:

• ATP ToughDrive 1 GB
• Corsair Flash Readout 1 GB
• Corsair Flash Voyager 512 MB
• Geil David 100 256 MB
• Kingmax Super Stick 256 MB
• Kingston DataTraveller 2.0 512 MB
• Kingston DataTaveller Elite 2 GB
• Kingston DataTraveller U3 Smart 1 GB
• MSI Mega Flash 128 MB
• OCZ Rally 512 MB
• OCZ Rally 2 GB
• OCZ Roadster 1 GB
• Patriot Xporter XT 2 GB

All of them are USB 2.0 and you may ask what is the difference between them besides their capacity. Well, there are a lot of differences. Geil David 100, OCZ Rally, Patriot Xporter XT and ATP ToughDrive use dual channel technology, achieving a performance higher than other models included in this roundup. Also, these four companies claim they have the fastest USB flash drive around, so we will be able to say which product is really the fastest one available in the market today.

Patriot Xporter XT and ATP ToughDrive use a rubber body making them waterproof and shockproof, imitating the idea introduced by Corsair with their Flash Voyager more than one year ago. But please remember what happened to our Flash Voyager after a while using it.

OCZ Roadster doesn’t compete for performance but for portability. It is one of the smallest USB flash drives around. To reduce its size OCZ soldered its flash chip inside its USB connector. The plastic body you see is just a protection.

Corsair Flash Readout also does not compete for performance but for innovative design. It is the first flash drive to carry a LCD display, which shows you the available space in the drive, in MB. You can also customize its label by just renaming the drive label on Windows. It also displays a pie chart with the amount of free space. What is most amazing is that this display doesn’t require any battery to work and it keeps turned on even when it isn’t connected to a PC.
