## Performance

The 1TB S90 Lite delivers 5,000 MB/s sequential read and 4,400 MB/s write throughput over PCIe 4.0 x4. These figures place it in the mid-tier of Gen4 performance, below the 7,400 MB/s ceiling of flagship drives but well above SATA SSDs limited to approximately 550 MB/s.

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.

## Endurance, TBW & Warranty

Addlink provides a five-year limited warranty on the S90 Lite series from the date of original purchase. Specific TBW endurance ratings for the S90 Lite 1TB have not been widely published by Addlink. Similar mid-range Gen4 DRAMless drives of 1TB capacity typically carry endurance ratings in the 600 to 800 TBW range. Warranty claims are processed through authorized Addlink retailers and regional distributors. For the most current warranty and endurance information, consult the official Addlink website or contact their technical support team. The five-year warranty term reflects confidence in the reliability of the drive components under normal consumer operating conditions.

## Pros and Cons

**Pros:**

- 5,000 MB/s reads deliver solid mid-range Gen4 performance
- 3D TLC NAND for better endurance than QLC alternatives
- HMB technology maintains performance without dedicated DRAM
- 1TB capacity suitable for gaming and general desktop use
- Five-year limited warranty from Addlink
**Cons:**

- DRAMless design limits sustained random performance
- Speeds below the 7,400 MB/s Gen4 flagship ceiling
- No published TBW endurance rating from Addlink
- SLC cache exhaustion under sustained multi-hundred-gigabyte transfers


## Verdict

The Addlink S90 Lite 1TB delivers capable mid-range PCIe 4.0 performance at a budget-friendly price point. With 3D TLC NAND flash and Host Memory Buffer technology, it achieves 5,000 MB/s reads and 4,400 MB/s writes, offering solid Gen4 speeds for everyday computing and gaming.

The DRAMless HMB design keeps costs down while maintaining acceptable everyday performance. Thermal requirements are modest, making the S90 Lite versatile across desktop and laptop platforms. If you want affordable Gen4 storage with 1TB capacity for a new build or upgrade, the S90 Lite 1TB is a practical option to consider.

## Frequently Asked Questions

### Does the Addlink S90 Lite 1TB have DRAM?

No, it uses Host Memory Buffer (HMB) technology instead of a dedicated DRAM chip. It borrows a small amount of system memory for the NAND mapping table.

### What controller does the S90 Lite use?

Addlink has not publicly disclosed the specific controller model. At 5,000 MB/s read speeds with HMB support, it is likely based on a mid-range Gen4 DRAMless controller.

### Is the S90 Lite good for gaming?

Yes, the 5,000 MB/s read speed provides fast game loading times, and the 1TB capacity holds a solid library of modern titles for most gamers.

### Does the S90 Lite need a heatsink?

The DRAMless controller generates moderate heat. A basic motherboard M.2 heatsink is recommended for sustained workloads, though it is not strictly required for everyday use.

### Is the S90 Lite compatible with PCIe 5.0 motherboards?

Yes, the drive works in PCIe 5.0 M.2 slots at its native Gen4 speeds of 5,000 MB/s read. It cannot utilize the extra Gen5 bandwidth but functions normally.

### What is the TBW endurance of the S90 Lite 1TB?

Addlink has not published specific TBW ratings for the S90 Lite. Similar mid-range Gen4 DRAMless drives of 1TB capacity typically carry 600 to 800 TBW ratings.
