Samsung Enterprise Solid State Drives (SSDs) are being used increasingly as data storage media in computing, communication, and multimedia devices. Most SSDs use NAND Flash memory as the storage media, which is capable of retaining data without an external power supply. A typical SSD consists of two main components: the data storage device and a controller for the storage device that acts as an interface between the SSD and the host system. The SSD controller manages the interfaces from both the host side and the device side, which includes mapping bad data blocks, caching read/write data, and error checking and correction (ECC); and the controller's built-in ROM contains the firmware needed to control the drive. An SSD is an example of an embedded system, and needs a Real-Time OS (RTOS) for its operation. Several open source and proprietary firmware solutions are available for SSD controllers

The primary advantage of using Samsung SSDs is their lack of moving parts, resulting in extremely short startup and shutdown/standby times. SSDs offer superior reliability compared to traditional Hard Disk Drives (HDDs). Advances in semiconductor flash memory technologies have enabled the development of SSDs that are equal in capacities to HDDs and can be used as direct replacements. SSDs also prove to be highly cost effective in-use due to their much lower power consumption and maintenance costs. As the world leader in semiconductor memory technology, Samsung offers a comprehensive range of SSDs for deployment in a wide range of devices across every industry segment.

In addition, the PM883 provides the following same powerful functions as the previous generation PM853T

Power-loss Protection. Protects from loss of data due to sudden power disconnections by using a tantalum capacitor build into the PM863 to safely and accurately copy and store user data written to the DRAM (the volatile memory in the SSD) to the NAND flash memory

  • End-to-end Protection. Safeguards user data in the PM863 along the entire data transfer path, from the host interface to the NAND flash memory, by duplicating the Cyclical Redundancy Check (CRC) and Error Check and Correct (ECC) at each section of the path to ensure accuracy and safety at all time.
  • Dynamic Thermal Throttling. Monitors the temperature of the SSD automatically and, if the SSD rises above safe levels, it forcibly delay I/O processing until the temperature of the SSD drops to normal levels, ensuring the safe use of expensive servers.
