COTS PXIe SSD RAID modules support up to 31 TB per slot

RADX Technologies recently launched the Trifecta-SSD family  of COTS, PXIe (and CPCIe), single-slot, NVMe SSD RAID modules. Applications targeted by the family include wideband, high-speed, data recording, playback, and storage. The company claims that the modules deliver the highest performance, capacity, and price-per-terabyte in the test and measurement market. They sustain 6.9-GB/s sequential write performance and >7-GB/s sequential read performance (depending on configuration and use).

Four or eight M.2 NVMe SSDs in a single-slot PXIe/CPCIe module are combined in Trifecta’s SSD PCIe Gen 3 × 8 architecture, supporting 8, 16, or 31 terabytes (TB). This is between 2× to 8× greater than single-slot SSD RAID modules on the market.

The market is demanding multiple missions and hours of record time, which would necessitate five PXIe slots per channel. Trifecta-SSDs were developed to address long-duration, multi-mission, wideband record, and playback requirements in a single PXIe slot. The modules comply with RoHS, FCC Part 15 Subpart B, Class A, CE, and MIL-PRF-28800F and support 64-bit Windows operating systems and select Linux distributions upon request.

Priced at $6,999 (8 TB), $13,999 (16 TB) and $19,999 (31 TB), the modules equate to one-half to one-third the price per terabyte of competitive products, according to the company. Delivery is
