![]() It delivers byte-addressable data access like you get with memory, at prices closer to traditional storage solutions. Not surprisingly, SCM shares some features with both DRAM and NAND flash storage. SCM falls between the traditional NAND storage used in today’s enterprise flash drives and DRAM, as shown in the chart below. Tape is cheap but slow, while DRAM is super-speedy but exceedingly pricey. SCM: A Bridge Between DDR and Today’s Enterprise Flash DrivesĬonsider the spectrum of enterprise storage options and the price vs. ![]() But, DDR SDRAM is also ultraexpensive.Īnother storage option is quickly gaining popularity as it offers higher performance than NAND Flash at lower costs than DDR SDRAM. Ultrafast data access exists in forms such as the latest double data rate (DDR) synchronous dynamic random-access memory (SDRAM). Enterprise storage administrators have long had to balance the need for better data access speed with budgetary constraints.
