RADX Technologies has announced the Venturi family of PXIe-SSD storage modules, designed to deliver high-performance, cost-effective data storage for data-intensive test and measurement (T&M) applications. These modules integrate patent-pending technology that leverages 15 mm, PCIe Gen 4 and Gen 5, data center–class U.2 and U.3 NVMe solid-state drives (SSDs) to provide sustained, sequential read and write rates of up to approximately 7.2 GB/sec and 7.1 GB/sec, respectively, in PXIe Gen 3 chassis.
The Venturi PXIe-SSD line supports a range of unformatted capacities—0.8 TB, 3.84 TB, 7.68 TB, 15.36 TB, 30.72 TB, and 61.44 TB—with custom options available. The 0.8 TB Extreme Endurance model is rated for 87.6 petabytes written (PBW), targeting circular-buffer and continuous-write tasks, while all models offer write endurance from 7 to 112 PBW. RADX claims this write endurance is up to 146 times higher than comparable M.2 RAID solutions. The family also features a new entry-level 3.84 TB model with a manufacturer’s suggested retail price (MSRP) of $4,999.
According to RADX, the use of a single data center SSD per module results in significant power and thermal management advantages, including a typical thermal design power of 38 W and operating temperatures normally below 50°C at a 23°C ambient. The modules are designed to avoid thermal throttling, a problem that can affect M.2 RAID units. Random read I/O performance is listed at up to 3.3 million IOPS, versus 1.6 million IOPS for many existing PXIe RAID products. Reliability is further enhanced, as each Venturi PXIe-SSD is rated for up to 2.5 million hours mean time between failure (MTBF) and comes with a standard three-year return-to-factory warranty. They are compatible with RT Linux, Linux, and Windows.
Becky Linton, Senior Engineer at SPHEREA US, emphasized operational improvements, noting, “Many of our engineering and production tester applications use circular buffers that need high sequential write performance concurrently with extreme write endurance,” said Becky Linton, SPHEREA US Senior Engineer. “Some of our multi-channel testers continuously stream pre-trigger data at over 6 GB/Sec per channel, twenty-four hours per day, for months at a time. With M.2-based RAID modules, we have to replace the SSDs weekly or monthly, which is very costly and is an operational nightmare for our production test customers. With Venturi, we can sustain up to a year of operation from a single, high-performance Data Center SSD per channel, which is a huge improvement in terms of operations complexity, total cost of ownership and overall customer satisfaction.”
Pricing across the Venturi model lineup ranges from $4,999 for the 3.84 TB module to $29,999 for the 61.44 TB module. Early units are available immediately with 45- to 60-day lead times after receipt of order; volume production with 30-day lead times is slated to begin in the first quarter of 2026. RADX designs and assembles the Venturi PXIe-SSD modules in the US, and modules are compliant with the Buy American Act (BAA) and Trade Agreements Act (TAA).
Primary applications include data center–class storage for PXIe-based real-time signal processing, radio-frequency (RF) and spectrum analysis, data recording and playback, and artificial intelligence (AI) training and inference platforms deployed in test and measurement environments. The modules will be on display at AOC 2025 in National Harbor, Maryland.
