A lot has happened in the USB 3.0 world since we took a look at Kingston's first ‘Ultimate 3.0′ drive this past fall, and thanks to some progressions, the company has just released a ‘G2′ variant of the drive.

The Kingston DataTraveler Ultimate G3 64GB USB 3.0 flash drive is the third generation product in the company's lineup, packing 64GB of capacity onto a form factor that can fit onto your key ring. But what about performance?

Fast speeds; capless design; durable; large capacity; good price

No encryption; could block adjacent USB ports

Most of us use a USB pen drive on some level or another, whether it is to keep offline document backups or to move files between work and home machines. Today we are looking at the new Kingston Data Traveler Ultimate 64GB drive which is the first USB 3.0 pen drive we have tested.

We have in our hands the Kingston's DataTraveler Ultimate 3.0 Generation 3 (DTU30G3), a USB 3.0 flash drive that supports data transfer rates of up to 150MB/s read and 70MB/s write, offering you the convenience of carrying files with incredible speed and ease.

Was looking for a 64GB USB 3.0 stick and bought this. The other (cheaper) Kingston datatravelers have terrible reviews on amazon...so be warned! I get 120 MB/s read (less than advertised) but 94 MB (more than advertised!) write. Tested with a 2GB file writing to and from a 400 MB/s SSD. It's great!

Significantly faster than USB 2.0 flash drives

A little on the chunky side; doesn't realise the full potential of USB 3.0

Kingston DataTraveler Ultimate 3.0 Generation 2 Review – Last year, Kingston released the DataTraveler Ultimate 3.0 USB flash drive, the fastest USB flash drive with a native USB 3.0 controller and comes in a whooping huge space, up to 64 GB (check Craving Tech's DataTraveler Ultimate 3.0 review ).

Even faster than the first generation model; Large capacity; USB 2 compatible; Can be attached to a keyring

Size a bit bulky; Apart from the speed; nothing else is new in the Generation 2 model

Slightly bigger and more expensive than a standard USB flash drive, but with many times

But my big complaint is that they seemed to have changed the interior design a bit. The drives I just got no longer have an LED to indicate activity. I needed this and assumed that since the first box had this, the rest would too. I was mistaken. I am NOT happy about this.

Works well for the price

I have bought two boxes of these (25 in each) separated by a couple of months; The first drive I tried died in a few minutes.
