4 TB NVMe storage

The Silicon Power UD90 provides four terabytes of PCIe 4.0 NVMe storage in an M.2 form factor. It suits desktop builders and laptop upgraders who need a single high-capacity drive for operating systems, applications and large media libraries.

PCIe 4.0 x4 interface

The drive connects through a PCI Express 4.0 x4 lane, which determines whether the motherboard can deliver its rated throughput. Systems limited to PCIe 3.0 will still work but at reduced sequential speeds.

Straightforward M.2 installation

Installation requires an available M.2 slot and a retaining screw; the module slides in at an angle and secures flat. Common issues include missing standoffs, slots that share bandwidth with other ports, and BIOS versions that need updating before the drive appears.
