Quick Answer: Will the WDS400T4B0E-00BKY0 work with my RAID controller?
The WDS400T4B0E-00BKY0 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 WDS400T4B0E-00BKY0 ship?
WDS400T4B0E-00BKY0 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 WDS400T4B0E-00BKY0 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 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.
Hypervisor Boot — ESXi, Hyper-V, Proxmox boot drives. Read-intensive (1 DWPD) is sufficient. Mirror two drives for redundancy.

Pro Disk Network Buyer’s Guide: SSDs
How to Pick the Right Drive Capacity for Your Use Case
For VMware vSAN deployments, the WDS400T4B0E-00BKY0 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 WDS400T4B0E-00BKY0 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.
