Mixing this drive in the same RAID volume with drives of different speed/capacity is supported but never recommended.

The P21517-B21 is deployed by US enterprises, MSPs, government, and education customers across multiple infrastructure scenarios. Below are the most common deployment patterns Pro Disk Network sees in real-world orders.
OLTP Database — SQL Server, PostgreSQL, MySQL, Oracle data and log volumes. Mixed-use SSDs (3 DWPD) recommended for transaction-heavy workloads.
VMware Datastore — ESXi 7/8 datastores hosting 30–80 VMs per drive. RAID 10 for write-intensive, RAID 5 for read-leaning VM mixes.
Citrix / Horizon VDI — Linked-clone master images and write-cache disks. Lower DWPD acceptable since VDI write patterns are bursty.
NoSQL & Real-Time Analytics — MongoDB, Cassandra, ClickHouse, Druid hot-tier nodes. NVMe variant strongly preferred over SAS/SATA for query latency.

Mixing this drive in the same RAID volume with drives of different speed/capacity is supported but never recommended.

How to Pick the Right Drive Capacity for Your Use Case
Sizing a storage drive correctly is the difference between a system that runs predictably for five years and one that you replace under emergency conditions at 18 months. For the P21517-B21, plan capacity around three numbers: working-set size, retention window, and overhead headroom. Working set is the actively-read data — databases, indexes, hot files. Retention window is how long you keep cold data online before tiering off. Overhead headroom should be 25-30%: drives run noticeably slower above 80% utilisation and metadata operations stall above 90%.
Drive Health Monitoring: SMART, Workload Rating, and Predictive Failure
Workload rating — expressed as TB written per year — matters more than raw capacity in choosing the P21517-B21 for sustained-write workloads. Consumer SATA drives are rated for 55 TB/year; enterprise SATA for 180-550 TB/year; enterprise SAS for 550 TB+/year; mixed-use NVMe for 1-3 PB/year over five years. Match the rating to your sustained write profile, then add 30% headroom.
