Swissbit N-20m2 SSD module

Swissbit’s N-20m2 SSD module, designed to deliver high-speed PCIe performance, is available in a small M.2 2230 form factor as well as standard dimensions of 2242 and 2280. The module utilises Swissbit’s EN-20 PCIe-BGA component to minimise PCB space requirements while offering a wide storage capacity range of up to 480 GB as well as 4-lane PCIe-3.1 and NVMe-1.3 compliance. It is targeted at small embedded systems and routers, acting as a boot device.

The product features industrial-grade 3D-NAND that supports an ambient temperature range from -40 to +85°C. The module combines high-grade NAND flash chips, a sophisticated PCIe controller and firmware that supports demanding applications. The PCIe 4-lane interface with backwards compatibility to single- or dual-lane system designs operates according to the latest PCIe-3.1 specification and offers high bandwidth up to 1600 MBps for sequential read and 770 MBps for sequential write. Random performance surpasses 145,000/130,000 IOPS for read and write and nearly doubles the bandwidth of SATA SSDs.

For low power consumption, the module has an HMB (host memory buffer) feature that uses system DRAM memory to maintain the flash translation table. Intelligent thermal management protects the long-term stability of the controller and maintains a continuous bandwidth even at the highest specified temperature of 85°C ambient. The NVMe protocol has been designed to efficiently use the bandwidth with a native non-volatile memory command set, resulting in ultralow latency.

Other features include end-to-end data path protection (ETEP), AES-256 encryption, LDPC error correction with full page fail recovery and a protection against sudden power loss. Data care management adds extra protection of the stored data at high operating temperatures. The SSD offers endurance of up to 1 DWPD (drive writes per day); for even higher endurance requirements, the product offers a 10-fold writability in full pSLC mode.
