Question:What type of disk devices are the highest performing and most expensive of all disk...

Storage Class Memory (SCM) represents a new class of storage technology that bridges the gap between traditional DRAM and NAND flash memory. SCM offers significantly lower latency and higher endurance compared to NAND flash, making it the highest-performing storage medium currently available. Due to its advanced technology and performance characteristics, SCM is also the most expensive among the listed options.

FC (Fibre Channel):A network protocol used for high-speed data transfer, not a type of disk device.

SATA (Serial ATA):Commonly used in consumer-grade storage; offers lower performance and cost.

SAS (Serial Attached SCSI):Offers better performance than SATA but still lags behind SSDs and SCM.

SSD (Solid State Drive):Provides faster data access than HDDs but is outperformed by SCM.

SCM (Storage Class Memory):Combines the speed of DRAM with the persistence of NAND, offering unparalleled performance.
