Stealth Solid State Drives (SSD)

SSD is the acronym for Solid State Drive. SSD's are highly reliable storage devices that use solid-state memory (NAND Flash) to store data. Stealth Computer SSD products emulate a standard 2.5" mobile hard drive and are a direct, no fuss plug-in replacement.

Given all the great advantages that a Solid State Drive (SSD) offers over a traditional hard disk drive (HDD) you would wonder why use a mechanical HDD at all. The main reason comes down to costs. NAND Flash memory chips cost far more per gigabyte than a traditional rotating platter based HDD. The good news is that Flash Memory technology has been dropping leading to the adoption and affordability of SSD products.

Stealth Computer has been delivering computer products with Solid State Drive technology for over 15 years. Justification for early SSD deployment was always based on the demands of the application. Whether it was for extreme temperatures, high shock, vibration, altitude or to operate reliably in high electromagnetic areas, costs were not the determining factors. The ability to operate reliably in harsh or extreme environments was very important.

In recent years SSD technology has grown exponentially making way for relatively low cost, high capacity drives. With large capacity Solid State Drives coming into existence, the traditional mechanical HDD has some strong competition in many niche computer applications.

Typical capacities of SSD's are currently 32GB, 64GB, 128GB and 256GB. Stealth offers SSD in two technologies, MLC and SLC. Please see our knowledge base to help you decide on the best SSD for your application Single Level Cell (SLC) or Multi Level Cell (MLC).

Justifying the use of SSD technology in today's computer applications has become easy when you consider the benefits and features achieved.
