## Summary description

Silicon Power UD90 is a 500 GB M.2 NVMe SSD using PCIe 4.0 x4 interface and 3D NAND memory. It supports NVMe 1.4, LDPC error correction, SLC caching and RAID, with End-to-End data protection and MTBF ~1,500,000 h. Sequential read/write speeds reach the PCIe 4.0 class (manufacturer lists up to ~4800–5000 MB/s read and ~2700–4200 MB/s write across sources). Compact M.2 form factor suits laptops and desktops; operating range 0–70 °C.

## Long description

The Silicon Power UD90 500 GB M.2 PCIe 4.0 NVMe SSD delivers high-speed storage for modern desktops and laptops. With sequential read speeds up to 4,800 MB/s and write speeds up to 4,200 MB/s, this M.2 form-factor drive is designed for systems that support PCIe 4.0 and for users who need fast file access and reduced load times. Built on 3D NAND and supporting NVMe 1.4, the UD90 balances performance and reliability in a compact 500 GB capacity.
Advantages
The UD90 offers substantially faster transfer rates than PCIe 3.0, providing up to twice the bandwidth for quicker downloads and shorter application load times. It supports Host Memory Buffer (HMB) technology and NVMe 1.4 for improved multitasking performance and lower latency. Reliability features include SLC caching for sustained read/write performance, LDPC error correction, RAID support and end-to-end (E2E) data protection. A free SP Toolbox utility is available to monitor SSD health and view device metrics.
Suitable for
Content creators and multimedia editing
Gaming and fast application loading
System boot drive for modern desktops and laptops with M.2 PCIe 4.0 slots
General high-performance storage and multitasking
Key specifications
Brand: Silicon Power
Model: UD90 (MPN SP500GBP44UD9005)
Capacity: 500 GB
Form factor: M.2
Interface: PCIe 4.0 x4, NVMe 1.4
Sequential read: up to 4,800 MB/s
Sequential write: up to 4,200 MB/s
Weight: 0.008 kg
How to use
Install the UD90 into an available M.2 PCIe 4.0 slot on a compatible motherboard, securing it with the appropriate screw. If your system supports PCIe 4.0, the drive will deliver maximum performance; it remains backward compatible with PCIe 3.0 but at reduced bandwidth. Initialize and format the drive in your operating system before use, then install your OS or use it as additional storage. Optionally install SP Toolbox to monitor health, temperature and total bytes written.
Usage recommendations
For best sustained performance, use the UD90 in systems with native PCIe 4.0 M.2 support and ensure adequate cooling on the M.2 slot. Regularly back up important data and use SP Toolbox to track drive health and firmware updates.
