Portable storage devices (PSDs) are designed to copy data from flash memory cards to a small hard disc. After the copying is completed, the memory card can be erased and re-used in the audio recorder or digital camera.
PSDs are storage devices. They are not designed for playback of the music or display of the photos transferred. This keeps the design simple, and the costs down. If you must have a device that can play back the files, look to a more expensive music player like an iPod or a device designed to show movies on the go. These gadgets won't perform the PSD function as quickly or easily, however.
PSDs usually have a built-in flash card reader that supports Compactflash. A few require you to attach the card reader externally (a disadvantage, IMO).
Don't use a USB cable to connect the recorder or camera to the PSD. Insert the memory card directly into the PSD. This transfers the files much faster, and does not waste battery power in the recorder.
A couple of years ago it looked like a PSD based on a portable CD or DVD recorder would be a good solution. Unfortunately, these machines transfer the files much more slowly (e.g., 30 minutes vs 5 minutes) and use much more battery power. They produce more heat, so proper ventilation is an issue. And they should be run on a level surface for best results. Given these issues, there's little reason to consider a PSD that records to a CD or DVD.
There are many companies that make PSDs. Two with good reputations for the fastest file copying, decent construction, and low price are Hyperdrive and Nexto. Both can be ordered without a hard drive if you want to use your own, or with a hard drive included.
Hyperdrive is somewhat larger and heavier than the Nexto. This is because Hyperdrive runs on AA cells that can easily be swapped out. The Hyperdrive also includes a flash card reader that supports multiple card types.
Sanho, a company in China, makes the Hyperdrive. In USA, you can purchase Hyperdrive from
www.hyperdrive.com or from
www.adorama.comOutside USA, Sanho sells its product as CompactDrive PD70X. (Note that there is a less desirable model called the PD7X. Don't order that one.) You can order from several retailers in Australia and Hong Kong. Price is the same or lower than USA, and delivery usually takes 2 or 3 days. Reliable vendors include
www.eastgear.com (Singapore) and
www.jaldigital.com.au (Australia)
Nexto is a second option. The Nexto CF is smaller and lighter than the Hyperdrive because it uses a rechargeable battery that can't be swapped out. The Nexto CF is somewhat faster at copying files. The Nexto CF has a slot for Compactflash only. Adapters for other card types are available.
The Nexto has a little better build quality than the Hyperdrive. The Nexto starts up and is ready to transfer files in a few seconds. The Hyperdrive takes longer.
Nexto has another advantage: It runs on a wide range of DC voltages. So it may fit in with your external battery setup better than the Hyperdrive.
The Nexto CF is available in USA from
www.mydigitaldiscount.com. Internationally, it is available from
www.jaldigital.com.au among others.
