Note that there is also Microsemi (a microchip company) that markets PCIe bridges dedicated to storage solutions. This seems a bit odd, since PCIe transports just a lot of small packets with memory transactions, and atomic memory transactions and interrupts. > There also have been videocards that embedded a direct path storage > functionality to maximaze GPU-NANDflash-based IO rates, although I havn't > seen ones which use > a lot of SATA or other spinning media compatible storage. Example is AMD Radeon Pro SSG 2TB (from 2016 ?), which uses 4 onboard NVME slots each with a 512 GB Samsing SM961 using presumably 4 PCIe lanes each. It support OpenCL and has a special API to access it's storage. https://www.amd.com/Documents/ssg-api-user-manual.pdf Today also 2TB M.2 SSDs are available, Samsung 860 EVO 2TB, times 4 would mean up to 8 TB of GPU attached storage (if compatible). This should translate for up to 20 minutes of 1600 MB/sec storage.
