Quick Answer: Will the ST3300656S work with my RAID controller?
The ST3300656S 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 ST3300656S ship?
If in stock, the ST3300656S ships in 1–3 business days. Most US ZIP codes receive next-business-day or 2-day delivery via FedEx/UPS Ground or Express. Bulk and pallet orders may need extra handling time; we confirm the ship date with your order.
The ST3300656S 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.

Pro Disk Network Buyer’s Guide: Server Hard Drive
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 ST3300656S, 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 ST3300656S 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.
