Exam DEA-1TT5 topic 1 question 47 discussion

Storage Class Memory (SCM) is a type of non-volatile memory that is slower than traditional Dynamic Random Access Memory (DRAM) but offers faster read and write speeds compared to flash memory. SCM is designed to provide a compromise between the speed of volatile memory like DRAM and the non-volatility of flash memory.

Slower than DRAM but read and write speeds are over 10 times faster than flash and can support higher IOPS while offering comparable throughput.

Slower than DRAM but read and write speeds are faster

A. SCM is slower than DRAM but read and write speeds are faster than flash is true about Storage Class Memory (SCM). Storage Class Memory (SCM) is a type of non-volatile memory that is designed to provide high-speed access to data with low latencies, similar to dynamic random access memory (DRAM). SCM is slower than DRAM in terms of access speeds, but it is faster than flash-based storage in terms of read and write speeds. SCM is often used as a high-performance alternative to traditional storage technologies, such as hard disk drives (HDDs) and solid state drives (SSDs). It is especially useful for applications that require fast access to large amounts of data, such as databases, big data analytics, and high-performance computing (HPC). SCM is typically more expensive than other types of storage, but it can offer significant performance improvements in certain scenarios.

I think the answer is A: Slower than DRAM but read and write speeds are over 10 times faster than flash and can support higher IOPS while offering comparable throughput.

SCM is memory-like performance, not cost
