Together, these technologies enable sustained multi\u2011tens\u2011of\u2011gigabytes\u2011per\u2011second disk write performance, supporting long\u2011duration data acquisition and recording for applications such as wideband signal collection, radar analysis, satellite monitoring, and scientific instrumentation.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img decoding=\"async\" src=\"https:\/\/www.mymepax.com\/pressdoc_files\/107643\/image\/ADQ35%20Digitizer.jpg_ico500.jpg\" alt=\"\"\/><\/figure>\n<\/div>\n\n\n<p><strong>Why high\u2011speed disk streaming matters<\/strong><\/p>\n\n\n\n<p>Modern data acquisition systems routinely generate tens of gigabytes per second of high\u2011fidelity data. Traditional file\u2011system\u2011based storage methods introduce latency, limit throughput, and cannot maintain continuous recording at full digitizer speed. To overcome these limitations, Teledyne SP Devices developed libads, a high\u2011performance NVMe streaming library that performs direct, block\u2011level writes to SSD arrays. By bypassing the operating system entirely, libads removes bottlenecks and delivers the sustained performance required for uninterrupted, high\u2011speed data capture when paired with the ADQ35 digitizer.<\/p>\n\n\n\n<p><strong>Disk streaming architecture<\/strong><\/p>\n\n\n\n<p>High\u2011performance disk streaming depends on efficient, deterministic data movement from digitizer to storage. At the core of this architecture is the ADQ35, which operates at up to 10GSPS in single\u2011channel mode or 5GSPS in dual\u2011channel mode, generating 20GB\/s of raw data. Its PCIe Gen3 interface supports up to 14GB\/s host transfer bandwidth per device, forming the foundation for extreme\u2011speed data capture.<\/p>\n\n\n\n<p>A suitable host PC must provide enough PCIe Gen4 or Gen5 x16 slots to accommodate digitizers, GPUs, and NVMe carrier boards without introducing bottlenecks. PCIe bifurcation or PCIe switches are often used to attach multiple NVMe drives in parallel. RAID arrays can be built using enterprise\u2011class NVMe SSDs such as the Kioxia CD8 for consistent long\u2011duration write performance, or high\u2011end consumer SSDs for cost\u2011efficient burst recording where SLC cache limitations are acceptable. By writing directly to raw disk sectors, libads minimises overhead and maximises throughput.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img decoding=\"async\" src=\"https:\/\/www.mymepax.com\/pressdoc_files\/107643\/image\/High-speed%20data%20acquisition%20system%20with%20digitizers.jpg_ico400.jpg\" alt=\"\"\/><\/figure>\n<\/div>\n\n\n<p><strong>The role of libads<\/strong><\/p>\n\n\n\n<p>libads manages direct data streaming from the ADQ35 to NVMe drives using large, contiguous block writes. This approach enables sustained write rates exceeding 25 GB\/s in suitable RAID configurations, while maintaining deterministic performance with minimal jitter. The library scales from compact systems to petabyte\u2011class RAID arrays and keeps CPU overhead low, allowing the host processor to focus on supervision or optional real\u2011time processing, including GPU\u2011accelerated workflows.<\/p>\n\n\n\n<p><strong>Example storage configurations<\/strong><\/p>\n\n\n\n<p>Enterprise\u2011class RAID systems built from five high\u2011performance SSDs \u2014 such as five Kioxia CD8 drives \u2014can deliver sustained write speeds of 25 GB\/s or more with total capacities around 75 TB. This configuration is ideal for multi\u2011hour recordings at full digitiser speed, offering consistent long\u2011term performance without throughput degradation.<\/p>\n\n\n\n<p>For more cost\u2011sensitive environments, a configuration using two high\u2011end consumer NVMe drives, such as the Kingston Fury Renegade G5, provides high burst write speeds suitable for several hundred gigabytes of recording. While performance tapers once the SLC cache is exhausted, this approach remains attractive for shorter captures or budget\u2011constrained applications.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img decoding=\"async\" src=\"https:\/\/www.mymepax.com\/pressdoc_files\/107643\/image\/Kioxa%20CD8%20Solid-State%20Disk.jpg_ico400.jpg\" alt=\"\"\/><\/figure>\n<\/div>\n\n\n<p><strong>Performanceconsiderations<\/strong><\/p>\n\n\n\n<p>Achieving maximum throughput depends on several factors, including proper PCIe lane allocation, the use of large block transfer sizes, the endurance and sustained performance characteristics of the selected SSDs, and adequate thermal management to prevent drive throttling during long\u2011duration recording.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Teledyne SP Devices recently announced a major advancement in high\u2011speed data acquisition through the combined capabilities of its high-speed ADQ3 data acquisition board family and the proprietary libads NVMe streaming library.
