Addlink S90 Lite 1TB PCIe 4.0 NVMe SSD Specifications (2026)
Addlink S90 Lite 1TB is a budget PCIe Gen4 x4 NVMe SSD with 3D TLC NAND and Host Memory Buffer technology delivering reads up to 5,000 MB/s and writes of 4,400 MB/s.
Controller & Memory
The Addlink S90 Lite 1TB is an entry-level PCIe 4.0 x4 NVMe SSD featuring 3D TLC NAND flash memory and a DRAMless controller architecture with Host Memory Buffer (HMB) support. Sequential read speeds reach 5,000 MB/s with writes up to 4,400 MB/s, placing it in the mid-range tier of Gen4 storage.
The S90 Lite uses a DRAMless controller design that relies on HMB technology, borrowing a small portion of system memory for the NAND mapping table. This approach reduces component cost while maintaining acceptable performance for everyday desktop and gaming workloads. The drive also supports dynamic SLC caching to accelerate write performance during burst operations.
Addlink positions the S90 Lite as a budget-friendly Gen4 option for cost-conscious builders who want faster-than-SATA performance. The 1TB capacity provides a solid amount of storage for operating systems, applications, and a growing library of modern games.
The drive uses the standard M.2 2280 form factor and generates moderate heat during operation. Its DRAMless design typically runs cooler than DRAM-equipped flagship Gen4 drives, making it suitable for builds with minimal M.2 cooling. Addlink is a storage brand known for offering competitive value in the budget and mid-range SSD segments, making the S90 Lite attractive for cost-conscious PC builders who prioritize capacity and Gen4 compatibility over absolute maximum speeds.

- MSI M580 2 TB: 14,600 MB/s read, 12,700 MB/s write
- MSI M580 4 TB: 14,600 MB/s read, 12,700 MB/s write
- Patriot Viper PV593 1 TB: 14,500 MB/s read, 14,000 MB/s write
- Patriot Viper PV593 2 TB: 14,500 MB/s read, 14,000 MB/s write
- Addlink S90 Lite 1 TB (this drive): 5,000 MB/s read, 4,400 MB/s write
Random 4K performance reaches 400,000 read IOPS and 800,000 write IOPS. The HMB DRAMless design shows limitations under heavy mixed workloads compared to DRAM-equipped alternatives, but for light desktop use, web browsing, and gaming the drive feels responsive and capable.
The dynamic SLC cache handles burst write operations well for typical consumer use. During prolonged file transfers exceeding the cache capacity, write speeds drop to the native TLC pace. The 1TB capacity provides a larger SLC cache pool than the 512GB variant, allowing longer sustained write bursts before exhausting.
Thermal output from the DRAMless controller is moderate, typically running cooler than flagship Gen4 drives with dedicated DRAM. The S90 Lite is suitable for most motherboard M.2 slots without requiring additional cooling, though a basic heatsink helps during sustained heavy workloads. For gamers and desktop users the 1TB capacity provides ample storage for a substantial game library alongside operating system and application files, making it a versatile all-in-one drive.
