SSD - Solid State Drive
A solid state drive (SSD) is a data storage device that uses non-volatile memory (NAND) such as flash or volatile memory such as SDRAM to store data instead of the spinning platters found in conventional hard disk drives (HDD). The technological advances in the SSD provide enhanced durability and performance as well as improved battery life. With up to 10% longer battery life and up to a 40% increase in data access efficiency, an Xplore Tablet PC with SSD provides an improved customer experience.
Providing protection against everyday knocks, bumps and jolts that occur during computing, Xplore Tablet PCs with the SSD provide a robust, rugged alternative for data storage in specialized environments such as construction, field service, inspection, home health, aviation and transportation.
Advantages of SSD:
- Faster startup - Since no spin-up required.
- Faster read time – In some cases, two times or more than that of the fastest hard drives.
- Faster random I/O than conventional disks.
- Low read and write latency (seek) time, hundreds of times faster than a mechanical disk
Faster boot and application launch time results in faster read and seek time but only if applications already reside in flash and are dependent on read speed more than other issues, e.g. OS bootup that detects devices will not be significantly sped up even with faster seeks and reads.
- Few to no mechanical parts
- Lower power consumption and heat production - no mechanical parts result in less power consumption.
- No noise: lack of mechanical parts makes the SSD completely silent.
- Better mechanical reliability: lack of mechanical parts results in less wear and tear. High level of ability to endure extreme shock, vibration and temperatures which apply to tablet PCs and other mobile devices when transported.
- Security - allowing a very quick "wipe" of all data stored.
- Deterministic performance - unlike mechanical hard drives, performance of SSDs is constant and deterministic across the entire storage. "Seek" time is constant and performance does not deteriorate as the media fills up.
