USB Storage Devices

Q: What is the technology behind a USB storage device?

A: USB Flash Drives are ultra-portable memory devices. The memory used in these drives are non-volatile, meaning that it does not need constant power to maintain information in memory. It is also solid-state media, which means that it does not have any moving parts like a hard drive, which has spinning platters. Since Flash drives do not have moving parts they are much more shock resistant than drives.

USB Flash drives also have much faster read times than standard hard drives. The memory within the casing of a USB Flash Drive is the same type of memory used in the memory cards we use with digital cameras, mobile phones, and PDAs. USB Flash Drives currently have a capacity of up to 8GB.

USB Hard Drives are standard 2.5″ or 3.5″ hard drives (SATA or IDE) in an external enclosure with a USB interface. The hard drives are the same types of hard drives found in desktops and laptops.
