The 303MG is a Dell ssds component with capacity 7.68 TB, form factor 2.5-inch, interface NVMe. Pro Disk Network sells the 303MG for $6,423.68 with same-day US shipping and a 30-day return guarantee.
Quick Answer: Will the 303MG work with my RAID controller?
The 303MG 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 303MG ship?
303MG 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 303MG 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.

Frequently Asked Questions about 303MG
Is the 303MG a genuine Dell part?
Yes. Pro Disk Network sources every 303MG as factory-original Dell inventory. New units arrive sealed in OEM packaging; refurbished units are pulled from decommissioned Dell servers, surface-tested, and re-warranted by Pro Disk Network for 90 days.
Will the 303MG work with my RAID controller?
The 303MG 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 303MG ship?
303MG 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.
What is the warranty on the 303MG?
New 303MG units carry the full Dell manufacturer warranty (typically 1 to 5 years depending on product line). Refurbished and bulk-OEM units include a Pro Disk Network advance-replacement warranty (90 days refurbished). DOA replacement is free within 30 days of receipt.

How to Pick the Right Drive Capacity for Your Use Case
For VMware vSAN deployments, the 303MG 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 303MG 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.
