Running 10,000+ channels of data through testing software isn’t just about having a fast computer—it’s about building a system that can handle the flood of information without dropping a single sample. Here’s the hardware you need to avoid crashes, lag, or data corruption.

Processor (CPU):
Skip consumer-grade chips. Aim for a 12-core or 16-core Xeon (e.g., Intel Xeon W-1290 or AMD EPYC 7302) or a modern multi-threaded Ryzen (3990X). These handle parallel processing—critical when 10k channels each need real-time analysis. Avoid anything with fewer than 8 cores; they’ll bottleneck at 5k+ channels.

Memory (RAM):
Rule of thumb: 1GB of RAM per 1,000 channels. For 10k channels, that’s 10GB minimum—but bump it to 16GB to handle spikes (e.g., sudden turbulence in wind tunnel tests). Use DDR4-3200 or faster; slower RAM creates delays when moving data from sensors to software.

Storage:

· Primary drive: A 1TB NVMe SSD (e.g., Samsung 990 Pro) for the software and active data. It reads/writes at 7,000 MB/s—10x faster than SATA SSDs—so the software can access data instantly.

· Secondary storage: A 10TB+ HDD (or RAID array) for archiving test data. Look for 7200 RPM drives to speed up long-term file retrieval.

Networking:
For distributed setups (sensors in a wind tunnel, software in a control room), use a 10-Gigabit Ethernet card and switch. 1-Gigabit works for 5k channels but chokes at 10k—you’ll see lag or dropped packets.

Graphics (GPU):
Not just for gaming—GPUs accelerate data visualization (e.g., 3D flow maps). A mid-range NVIDIA Quadro (e.g., T1000) or AMD Radeon Pro WX 3200 handles real-time rendering of 10k channels without slowing the CPU.

Power supply:
A 80+ Gold 750W PSU ensures stable power—critical when running multiple hard drives, a powerful CPU, and GPU. Unstable power causes random crashes during long tests.

Pro tip: Test with a “stress tool” (e.g., Prime95 for CPU, MemTest86 for RAM) before your first big experiment. If components fail under load, upgrade them—better to fix it in the lab than during a $10k test.
