Server NVMe SSD | U.2, M.2 Enterprise Solid State Drives – ICD
Server NVMe SSD — Maximum Storage Performance
NVMe is the fastest enterprise storage interface available. ICD stocks NVMe SSDs in U.2 (2.5″), M.2, and HHHL (PCIe add-in card) form factors for Dell PowerEdge, HPE ProLiant, and Lenovo ThinkSystem servers. Capacities from 240GB to 15.36TB.
NVMe vs SAS vs SATA — Performance Comparison
| Interface | Max Sequential Read | Max IOPS | Latency | Best For |
|---|---|---|---|---|
| NVMe (PCIe Gen4) | 7,000 MB/s | 1,000,000+ | <20 μs | Databases, AI/ML, high-performance |
| SAS 12Gbps | 2,100 MB/s | 400,000 | ~100 μs | Mixed workloads, reliability critical |
| SATA 6Gbps | 550 MB/s | 100,000 | ~150 μs | Read-heavy, boot drives, cost-sensitive |
NVMe SSD Form Factors
- U.2 (2.5″ 15mm) — Most common enterprise NVMe form factor. Hot-swappable in standard drive bays. Requires NVMe-capable backplane.
- M.2 (22110/2280) — Compact form factor for boot drives and M.2 slots. Limited by slot availability.
- HHHL (PCIe card) — Half-height, half-length add-in card. Uses PCIe x4/x8 slot directly. Highest capacity options.

Frequently Asked Questions
Does my server support NVMe SSD?
Most Dell 14th Gen+, HPE Gen10+, and Lenovo V2+ servers support NVMe. The server needs an NVMe-capable backplane (for U.2 drives) or PCIe slots (for HHHL cards). Provide your server model and ICD will confirm NVMe compatibility.
Can I mix NVMe and SAS drives in the same server?
Yes, many modern servers support mixed configurations with both NVMe and SAS/SATA bays. Dell calls these ‘universal’ bays. Check your server’s backplane configuration — some bays may be NVMe-only or SAS-only.
What’s the difference between Read Intensive and Mixed Use NVMe?
Read Intensive (RI) NVMe SSDs are designed for read-heavy workloads with 1 DWPD (drive writes per day). Mixed Use (MU) SSDs handle balanced read/write workloads with 3 DWPD. Choose based on your write intensity.
