Addlink has released the S93 NVMe 1.4 M.2 SSD series, designed for mobile computing devices, leveraging Gen 4 transfer rates and improved operational efficiency. The series conforms to the widely-used 2280 M.2 form factor specifications, with dimensions of 80mm by 22mm and a height of 2.25mm. Available storage options include 1TB, 2TB, and 4TB, utilizing 2,400MT/s 3D TLC NAND flash technology. The construction of the S93 features a single-sided high-density flash placement, contributing to its slim profile of 2.25mm, making it particularly fitting for ultra-thin laptops and devices with limited space. The S93 is noted for its reduced power consumption, which is approximately 35% lower than that of other Gen4x4 SSDs, enhancing its suitability for laptop usage where power efficiency is critical.

With a Gen4x4 NVMe controller from Maxio, THE MAP1602A WITH 4-channels and 2400MT/s 3D TLC NAND flash, the S93 reaches sequential read and write speeds up to 7400/6500 MB/s, respectively. It is built for compatibility with M.2 PCIe 3.0 and PCIe 5.0 slots, ensuring flexible integration across different systems. The device also features SLC caching and supports the host memory buffer (HMB), which is instrumental in achieving random read/write speeds up to 1,000K IOPS.

Known for its performance and often value, the SSD is an M.2 NVMe SSD that supports the PCI-Express 4.0 interface.  A non-volatile memory express (NVMe 1.4) capable M.2 form factor SSD, it is packed with unique Vertically stacked TLC written (3-bits per cell) NAND. In today's world, the performance numbers provided by a quality SATA3 SSD are still outstanding. However, with the more specialized NVMe SSDs, you can now have 10-fold performance, resulting in some impressive numbers across the board. With an M.2 2280 form factor of 8cm, the item will be compatible with the vast majority of ATX motherboards that support M.2. In any case, are you interested in learning more about the fundamental performance of this product? Well, it's all listed; on to the next pages and the remainder of the review.
