this is the reply from Kingston...... Based on the information that you provided, the part that you described as a DTHX30/256GB was determined to be counterfeit given that the markings on the device were inconsistent with genuine Kingston product markings.

The Kingston Data Traveler HyperX USB Flash Drive is a quality made device and is made of solid construction. I had a PNY drive fail and I was looking for a higher quality drive in the future. Kingston has delivered that quality and I highly recommend it.

This is an excellent 3.0 usb. The site does not tell you what the 3.0 transfer speeds are here is the information below.

Although during this year's CES many manufacturers presented impressive and innovative products there's no doubt that the most impressive storage product unveiled was the DataTraveler HyperX Predator 512GB USB 3.0 flash drive by Kingston.

- Build Quality (Zinc Metal Alloy Casing/Toshiba 19nm Toggle NAND Flash; - Read/Write Speeds (280MBs/180MBs; - Massive Storage Space (512GB; - SSD Type USB Flash Drive; - USB 3.0 Extension Cable

- Price (For Most People; - Drive Thickness (For Some

There are a lot of "USB 3" drives out there that seem to be more marketing than performance. This is not one of those drives. This thing is blazing fast and actually takes heavy advantage of USB 3.

-Fast; -Really fast

-Bulky; -Expensive (if not on sale

Couldn't use it with my Lenovo T430... the USB3.0 ports in this laptop (as with some other slim laptops) are slightly recessed under the laptop frame and because this memory stick is unusually bulky and large - it won't fit...I am not sure who design it and why they didn't think of it...

Fast

Bulky; Poor Design

Outstanding product with outstanding performance. Certainly it's one of the fastest USB drive out on the market. Excellent construction and reliability so far.

I chose Kingston because their products are top quality and well-designed. I plan on using this USB 3.0, 128 GB device as the data backup for my new Dell XPS 12 UltraBook, 128 GB SSD.

USB sticks, thumb drives, pen drives, call them what you will their usefulness cannot be overstated. In these times when most of us have at the least a computer and a console, but far more likely we have a couple of computers, a laptop, maybe one or two consoles, a TV with USB in etc.

Recently we published a huge group test of 32 USB 3.0 sticks with capacities of 32 GB and 64 GB. If that doesn't float your boat, you could always get a USB storage device with no less than 512 GB, called the HyperX Predator.
