Supercapacitors For Ssd Backup Power

摘要

Compared with hard-disk drives (HDDs), solid-state drives (SSDs) are more robust against shock, consume less power, use capacity more efficiently, and offer longer life, faster access times, and better read performance. However, SSDs face performance challenges in write speed due to some technical characteristics of NAND flash memory. But the write performance of NAND flash SSDs can be enhanced using protected cache memory - in particular SDRAM - with backup power supplied by a supercapacitor.
