I purchased this item a month back and the writing speed goes upto 20 MBPS which is Unbeatable and Transcend as always is the Best!
The Retractability of this model is the one point where I found it was a better option. My previous drives were not as efficient too! The pen drive is easy to carry and is quite tough.
If you want a fast flash drive, then this is the thing look no further as the saying goes "more options more confusion" and I have heard from my other friends the product is worth its money and is working very efficiently.
