USB flash drive

A small, portable flash memory card that plugs into a computer's USB port and functions as a portable hard drive. USB flash drives are touted as being easy-to-use as they are small enough to be carried in a pocket and can plug into any computer with a USB drive. USB flash drives have less storage capacity than an external hard drive, but they are smaller and more durable because they do not contain any internal moving parts.

USB flash drives also are called thumb drives, jump drives, pen drives, key drives, tokens, or simply USB drives.

FLASH DISK DESCRIPTION

The A25FB Flashpak® flash solid state disk (SSD) is powered by the patent-pending Adtron ArrayPro™ performance engine to deliver industry leading performances previously unachieved in a flash solid state disk. The I25FB leverages this unique ArrayPro technology to provide true sustained write and read performance.

These 2.5-inch Serial ATA (SATA) flash solid state disks can easily replace standard 2.5-inch hard disk drives (HDDs), providing full HDD functionality with higher reliability and superior performance. In addition, A25FB Flashpak flash solid state diskss contain no moving parts. The A25FB Flashpak flash SSDs are far superior to HDDs in terms of ruggedness, shock resistance, environmental resilience and performance in no-compromise applications.

To meet the unique data security requirements of defense and security applications, Adtron EraSure™ data security provides multiple levels of data elimination techniques. EraSure Clear provides a fast data elimination function that enables erasing of data in seconds. EraSure Sanitize uses an agency defined and unique customer defined pre-programmed sanitization procedure allowing full media declassification. Combined with the ArrayPro performance engine, EraSure Sanitize provides unparalleled sanitization performance. In addition, access control features include write protection and password login for added data security.

Solid State Hard Disk:

 

The current generation of solid state hard disk technology is being put to a wide variety of uses in defense and industrial applications. Where rotating drives may have been the necessary evil ten years ago, a solid state hard disk can now take its place, and offer the highest degree of reliability and best performance. Not having the Achilles heel of moving parts, (ergo, solid state) hard drive storage have virtually no acoustic signature, are extremely light weight, and require much less power than a typical 2.5" or 3.5" HDD.

With all of these advantages, however, one of the highest concern when implementing a solid state hard disk into your application is its durability. Adtron flash disks are capable of withstanding a higher degree of environmental distress while delivering exceptional write endurance in I/O intensive applications.

In addition to high durability, Adtron solid state hard disks deliver the industry's best sustained read and write rates without using volatile cache memory as a buffer between the host and the solid state media. The use of cache memory introduces a point of failure where data loss can be significant, especially if battery backup is not used. The Adtron ArrayPro^TM performance engine delivers high performance beyond that typically found in a comparable solid state hard disk product or an HDD.

For example, Adtron's I25FB IDE flash disk passed standard military standards testing conducted by National Technical Systems in Tempe, AZ. Beyond the standard MIL-STD-810F testing, MIL-S-901D tests demonstrate that the I25FB Flashpak flash disk is capable of withstanding shipboard shock loadings which may be incurred during wartime service due to the effects of weapon attacks while at sea. In separate MIL-STD-167-1 tests, the I25FB solid state hard disk proved resilient to internally and externally imposed shipboard vibrations, while subject to dry and damp heat conditions, necessary to operate in a shipboard environment.

In the first U. S. Navy application, the Adtron 16 GByte I25FB solid state hard disk with commercial temperature media is being installed in the Local Control Panels (LOCOPs) by Woodward Governor Company. The LOCOPs are designed to monitor and control the parameters required to start and operate the generator sets used on the CG-47 Ticonderoga class cruisers and DDG-51 Arleigh Burke class destroyers. "Compared to rotating mechanical hard drives, solid state flash disks deliver clear reliability and durability advantages for shipboard applications," stated Andy Cullis, Woodward's Military/Marine Account Manager. "Adtron's flash disks provide a very robust data storage solution, which is critical to meeting the Navy's shock, vibration, temperature and humidity requirements for the LOCOP."
