Review: Sanho HyperDrive Colorspace UDMA
I am the first to admit I’m paranoid about my data, especially digital captures I shoot on location. I strive to keep at least two copies of all my raw files at any one time. When shooting on location for extended periods, that means having a hefty supply of flash cards and a means of copying them to an external hard drive, and only reformatting the cards when I have two backups. Usually that means taking a laptop, card reader and an external hard drive with me on location. There is another solution that I recently investigated—the HyperDrive Colorspace UDMA photo backup device.
The HyperDrive Colorspace is essentially a self-contained, battery powered storage device that quickly copies contents of my flash cards directly to a huge hard drive, and has a large 3.2-inch external LCD display to view and edit (if I choose) the images. Measuring 5.25 x 2.95 x 1 inches and weighing only 10.5 ounces, this is a lightweight, portable solution that at the very least, allows me to quickly download contents of my flash cards in the field without the need of a laptop. With its fast USB 2.0 connectivity, I can copy the contents of the Colorspace to my laptop’s external drive each evening if I decide it’s worth taking all that extra equipment with me on a shoot. Now I have two copies of my images and can safely reformat the flash cards and continue to shoot. There are a number of advantages to taking such a device on location such as:
Data verification: As data from a flash card is copied to the internal drive inside the Colorspace, it uses what is called CRC copy verification. I’d be very hard pressed to format a flash card on location, at least until I know the one backup I’ve made has been verified. The product provides three differing verification schemes. Real Time Verify is the default and does not affect copy speed. If an error in the camera file is detected when it copies to the hard drive, I’m alerted immediately. Verify HDD and Verify Card use a slower checksum verification scheme that compares each file copied to the data on the card or drive. Knowing that the image data on the Colorspace is readable and has been copied from the flash card with data integrity provides a lot of peace of mind.
