CKYS's products are special versions of USB flash drives. I use similar drives to back-up all of my files. They are small -- perhaps the length & width of your pinky & about a third as thick (actual dimensions of the ones I use are 2.75 " long, 0.75" wide, & 0.26" thick). Incidentally, CKYS's new XS model is only 1.6" long, 0.74" wide, & 0.11" thick & weighs less than half an ounce!
I use one USB flash drive for each major topic -- my columns are on one, my newsletter on another, the corporate profiles I prepare on another, etc., etc. They plug into the USB 2.0 receptacles on my computers -- they are ultimately convenient to use. They are great for moving data from one computer to another.
One of CKYS's versions, called the "CyberKey" flash memory device, is superior to the ones you find at such stores as Staples in several ways. One important difference is the use of encryption that makes it almost impossible for others to decode. The applications in reducing fraud & copyright violations are huge. Each CyberKey has a unique digital key so only the owner can have access to the contained information.
CKYS's proprietary technology feature set includes "Bad Block Memory Management," "Application Launcher," "Digital Rights Management/Watermarking," & "Software Upgradeable." Each unit also includes SpyCop Corp.'s "Purely Private" encryption protection.
CyberKey supports all file types recognized by Microsoft Windows, Apple Mac OS, & Linux -- application files, OS files, & content specific file formats such as those for music, video, & graphics.
CKYS hardwires its proprietary & licensed software protocols into each CyberKey unit, which allows the information contained on the device to be as secure as any U.S. Government standard 128-bit encryption system possibly can be.
Conventional flash memory devices require that portions of applications be resident on every computer or the application website you may want to transfer data to or from in order to perform certain authentication functions. CyberKey's resident security software makes its system "user-centric." You do not have to have software loaded on those other computers, applications, or internet servers.
Data retention is about 10 years, each unit provides about 1,000,000 program/erase cycles, & I have found that saving files to & retrieving files from my flash memory devices appears to be just as fast as saving to or retrieving from my hard drives.
