Solid State Drive

Definition

Solid state drives use NAND flash memory instead of spinning magnetic platters, delivering dramatically lower latency and higher IOPS than HDDs. In cloud storage, SSD-backed volumes (AWS EBS gp3/io2, GCP SSD Persistent Disk) are the standard for database and transactional workloads.

The latest NVMe SSDs in instance store configurations achieve the highest throughput for latency-sensitive applications.
