Packaging and Unboxing

The SSD is shipped inside a paperboard box.


The addlink S68 256GB M.2 NVMe PCIe SSD has a compact 2280 M.2 form factor, making it compatible with most modern motherboards’ M.2 slots. Designed for gaming and hardware enthusiasts, it delivers high performance and is available in capacities up to 1TB, offering a competitive edge to gamers.

The addlink S68 utilizes 3D TLC NAND, addressing the challenges of planar NAND by stacking memory cells vertically. This technology enhances performance and endurance, balancing speed and cost. The SSD’s dimensions are 80x22x3.5mm, weighing 8.2g, without a dedicated driver on Windows 8.1 and 10. The PHISON PS5013-E13-31 controller supports PCIe Gen 3×4, complying with NVMe 1.3 standards, and employs a 32-bit microcontroller with native support for 3D TLC and QLC NAND flash. The SSD features 2x 128GB chips, totalling 256GB capacity, and comes with a 5-year warranty, operating between 0°C to 70°C.

Despite slightly reducing SSD prices over time, the challenge lies in the increasing cost of solutions with higher storage capacities. The price per GB still favours 3.5” HDDs over SSDs, especially PCIe SSDs, which are more expensive. Factors like the type of flash memory (SLC, MLC, TLC, QLC) further complicate the pricing, each with pros and cons regarding endurance and performance.

PRO TIP: The addlink S68 series is an excellent choice for budget-conscious consumers and gamers who prioritize compact form factor and competitive read and write speeds without needing a DRAM cache.

Speaking of features, the Addlink S68 256GB M.2 NVMe PCIe SSD is capable of:

  • End-to-end Data Path Protection
  • Thermal throttling SMART-ZIP
  • SMART Refresh
  • DriveLog
  • HBM (Host Memory Buffer)
  • TCG Pyrite

We have tested this drive on the Intel Z490 platform. The test bench setup is as follows:

To test the drive’s read and write speeds, we have used the following software running on Microsoft Windows 10 x64:

  • AS SSD 1.8.5636.37293
  • ATTO Disk Benchmark 3.05
  • CrystalDiskMark 6
  • Anvil Pro Storage Utilities 1.1.0
  • DiskBench
WARNING: Users with high-end SSD performance requirements or storage needs exceeding 1TB should explore alternative options, as the addlink S68 series employs a DRAM-less design for affordability.

Let’s take a look at the results.
