Quick Answer: Will the 400-ATHS work with my RAID controller?
The 400-ATHS 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-ATHS ship?
If in stock, the 400-ATHS ships same business day on US orders placed before 2 pm ET. Most US ZIP codes receive next-business-day or 2-day delivery via FedEx/UPS Ground or Express. Bulk and project orders shipping in pallets are typically dispatched within 24-48 hours.
The 400-ATHS 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.
VMware vSAN Capacity Tier — Used as bulk storage in all-flash and hybrid vSAN clusters. Pair with NVMe cache-tier drives for SLA-grade write throughput at half the cost of all-NVMe.
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.
New, Bulk, or Refurbished — Choosing Your Tier
Pro Disk Network offers the 400-ATHS across three procurement tiers. Each tier is fully functional and warranted; the choice comes down to budget, warranty length, and whether the deployment is production-critical or capacity-expansion.

Pro Disk Network Buyer’s Guide: Storage Devices
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 400-ATHS, 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 400-ATHS 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.
