Storage

Enterprise storage splits along two axes: interface (SAS, SATA, NVMe) and media (HDD, SATA/SAS SSD, NVMe SSD). SATA drives are the most cost-effective option for bulk, sequential-access storage. SAS drives add dual-port redundancy and typically higher sustained performance, making them a common choice for RAID arrays in production servers. NVMe drives connect directly over PCIe and deliver the lowest latency and highest IOPS, suited to databases and other I/O-intensive workloads. For SSDs specifically, check the endurance rating (DWPD — drive writes per day) against your workload's write intensity: read-heavy workloads can use lower-endurance, lower-cost drives, while write-heavy database or logging workloads need higher-endurance drives to avoid premature wear.
