Procurement FAQ
What form factors does the Samsung PM9A3 come in?
The PM9A3 is available in 2.5-inch U.2 (7mm, NVMe), M.2 (22110), and E1.S form factors. The U.2 version is most common for hot-swap server bays, while M.2 suits high-density servers and E1.S is designed for next-gen hyperscale data centers. Always confirm your server's backplane or slot before ordering.
What is the DWPD rating and what does it mean for my workload?
The PM9A3 is rated for 1 DWPD (Drive Write Per Day), meaning you can write the full capacity once every day over the 5-year warranty period. This makes it ideal for read-intensive workloads like boot, database indexing, and CDN. For heavy constant writes (e.g., high-frequency trading logs), consider higher-DWPD models like the PM1735 or the Solidigm D7-P5620 (3 DWPD).
Do these NVMe SSDs have power loss protection (PLP)?
Yes. All enterprise NVMe SSDs we carry — PM9A3, PM9D3a, D7-P5520, D7-P5620 — include capacitor-based hardware PLP. In the event of sudden power failure, the PLP circuit protects in-flight data and the NAND mapping table, preventing data corruption. This feature is absent in all consumer NVMe drives.
Are these drives compatible with Dell, HPE, Lenovo, and Supermicro servers?
Absolutely. All models are validated on major server platforms and listed on the VMware Compatibility Guide (VCG). They work with Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem, and Supermicro servers. If your deployment has specific firmware or platform compatibility requirements, please provide your exact server model so we can confirm compatibility before shipment.
What is the difference between the PM9A3 and a consumer SSD like the 990 PRO?
The PM9A3 is a data-center SSD built for 24/7 operation with consistent low-latency performance, power loss protection, end-to-end data protection, and a 5-year/1 DWPD warranty. The 990 PRO is a consumer drive optimized for burst performance in gaming and content creation — no PLP, no enterprise reliability features. Using a consumer drive in a production server environment leads to premature wear and data risk.
What capacities are available across the NVMe SSD lineup?
PM9A3: 960GB, 1.92TB, 3.84TB, 7.68TB. PM9D3a: 960GB, 1.92TB, 3.84TB, 7.68TB, 15.36TB. D7-P5520: 1.92TB, 3.84TB, 7.68TB, 15.36TB. D7-P5620: 1.6TB, 3.2TB, 6.4TB. Please specify model, capacity, and form factor (U.2) when requesting a quote.
Does the PM9A3 support TCG Opal encryption?
Yes. A self-encrypting drive (SED) version with TCG Opal 2.0 is available. If your deployment requires hardware-based encryption (e.g., finance or healthcare), please specify the SED model when ordering. We will provide the exact model number based on your security requirements.
What is the sequential read/write speed?
PM9A3: up to 6,900 MB/s sequential read / 4,100 MB/s write; 1,000K random read IOPS. PM9D3a: up to 7,000 MB/s read / 4,100 MB/s write; 2,500,000 hr MTBF. D7-P5520: up to 7,100 MB/s read / 4,200 MB/s write; 1,100K read IOPS. D7-P5620: 7,100/4,200 MB/s; 390K random write IOPS, 3 DWPD.
When should I choose D7-P5620 over D7-P5520?
Choose the D7-P5620 (3 DWPD) when your workload involves heavy sustained writes — high-frequency transaction logs, real-time analytics ingestion, or mixed read/write database environments. The D7-P5520 (1 DWPD) is sufficient for read-dominated workloads like boot, CDN caching, or AI inference.
What is the typical use case for these NVMe SSDs?
AI training and inference clusters, high-performance databases, cloud storage backends, virtualisation platforms, and any workload demanding consistent sub-millisecond latency with over 500K IOPS. These are the recommended drives for next-generation data center deployments.
