Quick Answer: Will the 400-AUYN work with my RAID controller?
The 400-AUYN operates with any standard SAS/SATA/NVMe-compatible RAID controller (Dell PERC, HPE Smart Array, LSI/Broadcom MegaRAID, Adaptec, IBM ServeRAID, Lenovo ThinkSystem RAID). Mixing this drive in the same RAID volume with drives of different speed/capacity is supported but never recommended.
How fast does the 400-AUYN ship?
400-AUYN orders placed before 3 pm ET ship the same business day from US warehouses. Delivery is next business day to most metro ZIPs via FedEx/UPS overnight; ground delivery covers remaining US in 1-4 business days.
The 400-AUYN 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.
Veeam Backup Repository — Cost-optimised backup target for Veeam B&R, Rubrik, or Cohesity primary backup tier. RAID 6 over 8–24 drives delivers 100+ TB usable per server.
Splunk Warm/Cold Tier — Appropriate for Splunk warm/cold/frozen indexes where ingest write rates are below 200 MB/s per node. Avoid for hot-tier indexes — use NVMe instead.
File Server / SMB Shares — General-purpose Windows Server / Samba shares for departmental file storage. RAID 5 for capacity, RAID 10 for IOPS-sensitive workloads.
Object Storage (Ceph / MinIO) — JBOD presentation behind Ceph OSDs or MinIO erasure-coded pools. Mix with NVMe metadata drives for production object stores.

Pro Disk Network Buyer’s Guide: Server Hard Drive
How to Pick the Right Drive Capacity for Your Use Case
For VMware vSAN deployments, the 400-AUYN is best deployed in the capacity tier with NVMe cache drives in front. Size the cache layer at 10% of usable capacity for write-intensive workloads and 5% for read-leaning workloads. For Veeam backup repositories, plan around 1.5× the size of your protected estate to allow for incremental forever chains plus synthetic fulls. Splunk warm tier sizing should follow the daily ingest rate × retention days × 1.6 compression overhead.
Drive Health Monitoring: SMART, Workload Rating, and Predictive Failure
For VMware ESXi 8 hosts, enable vSphere's predictive-failure analysis on the 400-AUYN via the host's storage device list. The host queries SMART on a regular cadence and surfaces yellow/red warnings in vCenter before the drive fails outright. On Linux, use smartctl piped to your monitoring system; on Windows Server, Storage Spaces exposes health state directly in Server Manager.
