rootstrust Flash Drives
Originally (2013 - 2019) we sold the rootstrust 32 GB USB 3.0 Universal Flash Drive on a high-quality, fast SanDisk Extreme SDCZ80-32G device. Unfortunately, that device is no longer produced. Today we offer a SanDisk Extreme SDCZ800-064G (our 64 GB flash drive) and a SanDisk Extreme PRO SDCZ-880-128G-GAM46 (our 128 GB flash drive). The table below illustrates how the 64 GB and 128 GB drives compare with their 32 GB ancestor. As you can see, the 64 GB model has a slower read speed than its 32 GB predecessor.
For most people 32 GB would probably be more than sufficient storage for a rootstrust flash drive, however most of the 32 GB devices currently on the market are not of the highest quality and tend to be somewhat slow. Flash drive manufacturers often make their higher capacity, faster, more reliable devices their flagship models. Five years ago the SanDisk Extreme SDCZ80-32G fell into that category. Today one must go with a higher capacity drive to get the equivalent or better quality.
The universal rootstrust flash drives are called thus because they are compatible with Windows, macOS and Linux and support both 32-bit and 64-bit processors. That is no easy task, since there is no one file system type that is usable by all three. Windows and macOS have FAT32 in common. Linux can read from and write to a FAT32 partition, but can only execute a program, that resides on a Linux file system. The universal drives have a large FAT32 partition for rootstrust, the macOS and Windows versions of Java and plenty of space for your files. There is also a small Linux partition that is required for the Linux version of Java. Universal rootstrust flash drives cannot be used on Chrome OS.

Operating System Specific Flash Drives
Some rootstrust users are not interested in universality. They are tied to one operating system and have perhaps several computers at home and work running that OS. For example, you might have an iMac and a MacBook Air at home and a Mac Mini at work. You are not authorized to install personal software on your work computer, but you are permitted to use the Internet during your lunch break. So you run rootstrust from your flash drive and update your database with data and files you find via web surfing. After work, at home you update the rootstrust database on the hard drive of your iMac and/or MacBook Air. If you had downloaded and linked files to the flash drive database, you could copy them to your home computer(s) by using rootstrust's File Cabinet synchronization feature.
