In the pictures below ou can compare it to a previous Rally 512MB stick and the new Corsair 1GB readout drive that sports a fancy display. The OCZ traveller is considerably smaller than both of them.

It is still twice the size of the USB connector as the memory chip is housed in the extension of the connector. You need to open the USB stick to see the USB connector and use the device. And for this you need to use your nail, so it is not that convenient but you could also use a pen as a tiny crowbar to crack it open. It is not that hard but it would be nice if you could open it with your fingers only. Once you open the USB key, as it folds down to its plastic casing you can see the size of it.
If there is an even smaller USB with 1GB at this point we haven't seen one or heard about it. Sony may have
thinner ones but we're not sure about smaller.
When it comes to a copying speed you would be surprised. It is almost identical to its bigger brothers. It takes some hundred and ten seconds to copy a 700MB AVI file. We got a 6.36MB/s average speed on big files, some forty percent slower than three-times-bigger Corsair Readout 1GB drive. Both have the same memory capacity if in differnt size casings. It takes exactly fifteen seconds to copy a folder with sixty files in it and seven seconds to copy nine MP3 files ffrom the Justice for All album. Copying smaller files is faster than on the Readout device.

In Short
This is a lot of memory packed in a very nice, small design. It will fit in just about any pocket and for the
1GB one you won't need to spend more than $24.99 plus the shipping costs, at least this is how much Newegg charges for
it. It is currently out of stock but it should be available shortly, at least we hope so.
OCZ offers three year warranty for this small device and we are sure that you will want to buy the mini 32GB memory stick or whatever flash drive comes for the same $25 price. It is a super small and neat device and we don't know what else could you ask from your super small USB key. ?
