Quick Answer: Will the LD20A011-02-A work with my RAID controller?
The LD20A011-02-A 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 LD20A011-02-A ship?
Pro Disk Network dispatches the LD20A011-02-A same-day on orders confirmed before 2 pm ET. Multi-pallet projects requiring crating ship within 2 business days. International shipping (Canada, Mexico, EU, APAC) takes 3-7 business days via DHL Express or FedEx International Priority.
The LD20A011-02-A 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.
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.
New, Bulk, or Refurbished — Choosing Your Tier
Pro Disk Network offers the LD20A011-02-A 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.

Frequently Asked Questions about LD20A011-02-A
Is the LD20A011-02-A a genuine Quantum part?
Yes. Pro Disk Network sources every LD20A011-02-A as factory-original Quantum inventory verified against the manufacturer parts registry before listing. New units arrive sealed in OEM packaging; refurbished units are pulled from decommissioned Quantum servers, surface-tested, and re-warranted by Pro Disk Network for 12 months.
Will the LD20A011-02-A work with my RAID controller?
The LD20A011-02-A 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 LD20A011-02-A ship?
Pro Disk Network dispatches the LD20A011-02-A same-day on orders confirmed before 2 pm ET. Multi-pallet projects requiring crating ship within 2 business days. International shipping (Canada, Mexico, EU, APAC) takes 3-7 business days via DHL Express or FedEx International Priority.
What is the warranty on the LD20A011-02-A?
New LD20A011-02-A units carry the full Quantum manufacturer warranty (typically 1 to 5 years depending on product line). Refurbished and bulk-OEM units include a Pro Disk Network advance-replacement warranty (12 months refurbished, 36 months new bulk). DOA replacement is free within 30 days of receipt.
Do you offer bulk pricing for the LD20A011-02-A?
Yes. Pro Disk Network offers automatic volume discounts at 10, 25, 50, and 100+ unit tiers. Net 30 terms are available for verified businesses, government, and education buyers. Email sales@prodisknetwork.com with the quantity and target ship date for a quote within one business day.
How to Pick the Right Drive Capacity for Your Use Case
If the LD20A011-02-A is going into a RAID array, choose RAID 6 over RAID 5 for any capacity tier built from drives larger than 4 TB. The probability of a second drive failing during rebuild from a 6+ TB rebuild window is high enough that single-parity is no longer responsible. For all-flash arrays, RAID 10 still wins on write-amplification-sensitive workloads (OLTP databases, VDI write-cache).
Drive Health Monitoring: SMART, Workload Rating, and Predictive Failure
Once the LD20A011-02-A is in production, the single most impactful operational practice is SMART monitoring tied to your existing alerting stack. SMART attributes 187 (reported uncorrectable errors), 197 (current pending sector count), and 198 (offline uncorrectable sector count) are the leading indicators of impending drive failure. Alert on non-zero values, not just on absolute thresholds; once these attributes leave zero, the drive has typically 30-90 days of useful life remaining.
