Wear-Leveling refers to the practice of ensuring certain NAND blocks aren’t written and erased more often than others. By preventing the overuse of particular blocks which could lead to device failure or data loss, Wear-Leveling therefore improves the life expectancy and endurance of Flash products.
Flash-based storage devices are different in the way they deal with previously deleted data compared to traditional disks. Data must be erased first before new data can be written to the same block in SSDs. Garbage Collection copies in-use data to a new block, and then deletes all data from the old one.
TRIM is a command with the help of which the operating system can tell the SSD which blocks are no longer needed and can be deleted, or are marked as free for rewriting. With the TRIM command, it not only reduces the Write Amplifier Factor (WAF) but also boost the data access speeds.
Over-Provisioning is a technology where a certain portion of the physical capacity of the memory is reserved for carrying out garbage collection, wear-leveling and bad block management. It effectively reduces the attribute of write amplification and extends the lifespan of an SSD.
Use of digital and video monitoring has expanded by leaps and bounds, and has become more sophisticated for transmitting digital signals. Monitoring systems are now expected to provide megapixel quality on a 24/7 basis, whether it’s for safety, personal or business protection, crime prevention, or for other types of content analysis such as facial analysis and streaming data. When not transmitting recorded images by digital signal, the surveillance system in the analog setting functions as a monitoring tool for safety concerns. In either mode of operation, SMART Modular offers a variety of storage solutions for high-performance monitoring needs.
