Secure USB flash drives protect the data stored on them from access by unauthorized users. USB flash drive products have been on the market since 2000, and their use is increasing exponentially. [ 1 ] [ 2 ] As businesses have increased demand for these drives, manufacturers are producing faster devices with greater data storage capacities.
Storage security is a specialty area of security that is concerned with securing data storage systems and ecosystems and the data that resides on these systems. Introduction [ edit ]
Solid-state storage (SSS) is non-volatile computer storage that has no moving parts; it uses only electronic circuits. This solid-state design dramatically differs from the commonly-used competing technology of electromechanical magnetic storage which uses moving media coated with magnetic material .

The use of electronic storage has also been increasing in recent years, which requires more comprehensive research and understanding of the risks that it may pose. Currently, data mining and storage techniques are only able to store limited amounts of information. This reduces the efficacy of data storage and increases the costs of storing data.
Software-based security solutions encrypt the data to protect it from theft. However, a malicious program or a hacker could corrupt the data to make it unrecoverable, making the system unusable. Hardware-based security solutions prevent read and write access to data, which provides very strong protection against tampering and unauthorized access.
Hierarchical storage management (HSM), also known as tiered storage, [1] is a data storage and data management technique that automatically moves data between high-cost and low-cost storage media. HSM systems exist because high-speed storage devices, such as solid-state drive arrays, are more expensive (per byte stored) than slower devices ...
Direct-attached storage (DAS) is digital storage directly attached to the computer accessing it, as opposed to storage accessed over a computer network (i.e. network-attached storage). DAS consists of one or more storage units such as hard drives , solid-state drives , optical disc drives within an external enclosure .
