Review: Transcend JetFlash 620 64GB
Manufactured: March 2011
Reviewed by: Seán Byrne

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 more rugged than removable disks and some are small enough to fit on a keychain.

In this review, we will take a look at the performance, how it handles with various file systems such as exFAT and NTFS, its encryption software and how well its Private Zone performs.

Transcend Company Information

Retail packaging

The Transcend JetFlash pen drive came in retail packaging, as shown in the following images:

Front / Back

What’s inside the package?

The following shows what the pen drive came with.

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 products

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:


Reverse side

Cap removed

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:
