- PCI Express Gen4 x4 interface
- Low Profile PCIe form factor
- Designed for compatible TeraStation 51220RH and 71210RH series systems
- 3-year warranty
NVMe SSD Caching
The OP-NVSSD-512G is designed to accelerate storage operations through NVMe SSD caching on compatible TeraStation systems. Buffalo's published testing demonstrates improvements in sequential and random SMB performance when SSD caching is enabled, with results dependent on the NAS configuration, cache mode, workload, and test environment.
PCIe Gen4 x4 Interface
The SSD uses PCI Express Base Specification Revision 4.0 with a PCIe Gen4 x4 interface. Buffalo specifies a Low Profile PCIe form factor, with a rated voltage of 12V/3.3V and maximum power consumption of approximately 12.6W.
Compatible TeraStation Systems
Buffalo identifies the OP-NVSSD-512G as an SSD cache option for compatible TeraStation 51220RH and 71210RH series systems. The exact TeraStation model should be verified before deployment.
Physical and Environmental Specifications
The unit measures 69 × 168 × 19mm excluding the bracket. Buffalo specifies a 64.0g weight for the 512GB version, an operating temperature range of 0°C to 40°C, and operating humidity of 10% to 85%.
DC Supplies Product Note
The OP-NVSSD-512G is a TeraStation-specific SSD cache option rather than a general-purpose standalone NVMe upgrade. Confirm compatibility with the exact Buffalo TeraStation model before installation. Buffalo specifies a 3-year warranty, with write warranty coverage excluded after the SSD reaches its guaranteed total bytes written (TBW) limit.
