Closer Look

The addlink S70 256GB M.2 NVMe PCIe SSD has an M.2 form factor of 2280. It is an M Key SSD compatible with most M.2 slots on modern motherboards.

Over time, I’ve noticed a slight dip in SSD prices, but the struggle persists as Solid State Drives become pricier with higher storage capacities. Opting for 3.5” HDDs still makes more financial sense, especially compared to SSDs, particularly PCIe SSDs. The choice of flash memory, be it SLC, MLC, TLC, or QLC, adds another layer of complexity. In the consumer-grade SSD realm, TLC is the go-to.

Going for TLC (3 bits per cell) means embracing lower prices and a boost in storage. However, there’s a trade-off – performance takes a hit, and endurance becomes a concern. Now, diving into my experience with the addlink S70 – it’s all about that 3D TLC NAND. This tech tackles density challenges, bringing in higher performance and endurance.

Picture this: 3D NAND stacks memory cells vertically, giving me improved data cycles and throughput in a more compact form. So, here’s a glimpse into my journey with the addlink S70 M.2 NVMe PCIe SSDs and the background of the 3D TLC NAND that powers it. Let’s check out the addlink 256GB M.2 NVMe PCIe SSD: compact at 80x22x2.3mm and 8.2g. No dedicated driver is needed for Windows 8.1 and 10; Windows 7 requires one. The blue PCB houses a sticker with key details – I didn’t remove it for this retail unit. The sticker proudly boasts the addlink brand, 256GB capacity, and NVMe interface.

The backside of the drive features a white sticker covering two flash chips, displaying the manufacturer’s website, capacity, model, and part number. It’s a dual-sided PCB used consistently across SSD densities in this lineup. As for features, the addlink S70 256GB M.2 NVMe PCIe SSD boasts TRIMM DEVSLP, Garbage Collection, ECC, S.M.A.R.T, SLC Caching, Wear Leveling, Bad Block Management, Over-Provision, and RAID Protection. Engineered with a RAID engine and LDPC coding for data security, it guarantees 1,800,000 MTBF and a 5-year warranty.

WARNING: If planning to add an aftermarket heat sink, note that the S70 has a dual-sided PCB, so ensure the heat sink accommodates both sides of the SSD.

The operating temperature is 0°C to 70°C, the storage temperature is -40 °C to 85°C, and the write endurance is rated at 350 TBW. This SSD uses DDR3L caching with 3D TLC flash from Toshiba, 4x 64GB flash chips, and a Phison E12 controller. Expect speeds of up to 3000MB/s read and 1000MB/s write, with Random Read/Write speeds at 95K and 94K, respectively. Keep in mind that actual speeds may vary based on system specifications and testing software. Synthetic benchmarks will validate these figures.

The drive is using over-provisioning. Out of 256GB, 238GB is available for the user. The over-provisioning reserves a certain space of the NAND flash memory to perform some background memory management for the controller. The above picture shows the SSD detected in the UEFI of the motherboard.


We have tested this drive on the X99 platform. The test bench setup is as follows:

AS SSD Benchmarks

Let’s take a look at the results.

ATTO Disk Benchmark
