2 TB PCIe 4.0 Internal SSD

The Silicon Power UD90 is a 2 TB M.2 2280 drive built for consumers who need fast storage in a standard desktop or laptop slot. It uses 3D NAND flash and connects through a PCI-Express 4.0 x4 link. The drive targets creators and multitaskers who want shorter load times without paying a premium for flagship hardware.

NVMe 1.4 and HMB support

Firmware enables NVMe 1.4 and Host Memory Buffer technology, which lets the controller borrow a slice of system RAM for mapping tables. This lowers latency and keeps random performance steady during mixed workloads. SLC caching absorbs write bursts, while LDPC error correction guards data integrity across the NAND array.

PCIe 4.0 x4 bandwidth ceiling

Sequential reads top out at 5000 MBps and writes at 4800 MBps, but only when the host platform supplies a full PCIe 4.0 x4 connection. On a PCIe 3.0 slot the link halves to 3.0 speeds, cutting throughput roughly in half. The controller cannot exceed the electrical limits of the bus it sits on.

FeaturesTo bolster its multi-tasking factor even further, the UD90 takes advantage of increased bandwidth when used in conjunction with motherboards equipped with PCIe 4.0 slots. In fact, it has nearly double the bandwidth of PCIe 3.0 for shorter download times and the ability to download more files within the same amount of time.
An SSD's speed is meaningless without the ability to handle that speed reliably. The UD90 achieves improved sequential read/write and random read/write performance with support for SLC Caching. At the same time, it supports low density parity check (LDPC) coding to
