JMR SiloStor™

The newly developed JMR SiloStor NVMe SSD drives are ideal for compute intensive workflows including HPC, data centers, genome research, content
creation, CGI/Animation, codec processing and gaming, to name a few. The SiloStor family comes in three configurations.

  • Single drive module NVMe/PCIe: x4 PCIe connectivity, available in 512GB/1TB/2TB capacities. Half-height, half-length card
  • Dual drive module NVMe/PCIe: x8 connectivity, available in 1TB/2TB/4TB capacities. Half-height, half-length card
  • Quad drive module NVMe/PCIe: x8 connectivity, available in 2TB/4TB/8TB capacities. Half-height, full-length card

The Dual drive and Quad drive cards incorporate a PCIe switch and the drives can be striped (on a single card) for additional performance.
All SiloStor designs incorporate active heatsink coolers on the drive modules themselves, maintaining low operating temperature even during
intensive sequential write operations.
The single drive unit utilizes x4 PCIe (Gen 2 or Gen 3); the dual drive and quad drive units utilize x8 PCIe (Gen 2 or Gen 3) and can fit expansion slots
having more lanes than required, e.g., the x4 single-drive SiloStor works in x4, x8 or x16 slots, etc.
