Transcend has kindly given us a lend of its
JetFlash 620 64GB secure USB pen drive for review, featuring a throughput of up
to 32MB/s read and 18MB/s write and a Private Zone which is a password
protected hidden volume using 256-bit AES encryption. 

USB pen drives have come on a long way
since the very first pen drives that held just 64MB of data.  Before the pen
drive, the only way to carry a large quantity of data was with a removable
media drive, such as Zip Disk and recordable CD/DVD.  USB pen drives have the
huge advantage in that they work on pretty much any PC with a USB port, are

What’s inside the package?

The following shows what the pen drive came

The package consists of the following:

  • Transcend JetFlash Ultra Speed 620 64GB
    pen drive
  • Card with warranty & password
    security usage info
  • Flyer showing Transcend’s range of pen
    drive products
  • Flyer showing Transcend’s media player

The pen drive is simply plug & play, so
nothing other than the pen drive is required to get started.  The security
software is preloaded on the pen drive itself.

Now, let’s take a look at the drive itself:

The pen drive itself is very compact and is
slightly wider and about the same thickness as a USB ‘A’ plug, so should easily
fit in USB ports that have limited space. 

Operation mode indication

Like most pen drives, this one has an LED
that serves to indicate power and activity.  When powered up, it flashes blue to
indicate activity and remains solidly lit when idle. 

The following image shows it lit while
plugged in my Netbook:
