VT-PM8 & VT-PM16 Persistent Memory Drive
![$gallery[0]['title']](https://www.vikingtechnology.com/wp-content/uploads/VT-PM-8-16-drives_front.png)
VT-PM drives, part of Viking’s persistent memory technology family of products, are 2.5″ U.2 NVMe PCIe Gen3 drives optimized to Enterprise-grade with Radian Memory System’s architecture technology. The VT-PM8 and VT-PM16 are persistent memory drives that deliver performance and unlimited write endurance similar to that of DRAM, while simultaneously providing the data persistency desired for enterprise applications.
Viking Technology’s VT-PM drives come with a U.2 NVMe PCIe interface offering enterprise OEMs the ease of deployment for persistent memory unseen in the market today. Alternative developments of persistent memory architecture utilizes NVDIMM technology, a non-volatile memory module that attaches to DDR4 memory sockets, which can limit configurations and utilization of persistent memory due to number of sockets. By enabling the VT-PM8 and VT-PM16 behind the industry-standard NVMe interface, OEMs are able to access the drive via normal block or programmed I/O (mmap) byte addressable accesses; without firmware or HW requirements.
