addlink, a Taiwanese manufacturer, has many lines of storage products and recently released a new series of PCIe Gen4 drives in the compact form of M2230 that aim for portable warriors, who need extra speed at affordable prices. The S91 series comes to fulfill storage needs on the go for M2230 users, like the well-known SteamDeck or other devices that use such a small size storage format.

The addlink S91 series is a line-up of M.2 2230 PCIe Gen4x4 SSD designed for small mobile devices, *including select models from Valve Steam Deck, Microsoft Surface, and popular laptop/tablet brands with 2230/2242 PCIe NVMe drives. It features a PCIe Gen4x4 interface and delivers fast performance with sequential read speeds of up to 5000MB/s for the latest Intel and AMD platforms while complying with the PCIe Gen3 standards. The S91 SSD is built with reliable 3D NAND to offer great value and is perfect for gamers, content creators, and engineers who demand intensive use of cutting-edge technology.

The S91 delivers speeds up to 50 times faster than a microSD USH-I card. With its small form factor M.2 2230 and high storage capacity of up to 2TB, it provides a perfect storage solution for laptops, tablets, and gaming devices with limited internal storage space. Therefore you no longer have to rely on slow-speed microSD cards to expand your storage capacity.

Equipped with SLC caching feature, the drive delivers better performance and a smoother user experience. Additionally, it supports a host memory buffer (HMB) that enables the S91 2230 SSD to achieve even higher performance by utilizing the memory resources of the host. Consequently, it maximizes random read/write performance, faster loading times, and lag-free multitasking.

The S91 SSD is equipped with a new PCIe 4.0 controller, as well as the latest LDPC ECC, wear leveling, bad block management, and over-provisioning technology to ensure data accuracy and prolong its lifespan. It is compatible with the latest Intel and AMD platforms, as well as most PCs, laptops, and certain tablet/gaming devices from major brands. Available in 512GB, 1TB, and 2TB capacities, the S91 also comes with addlink’s ***limited five-year warranty, giving users additional peace of mind. Whether you're a gaming or hardware enthusiast looking to build or upgrade your device, the S91 offers an ideal storage solution.
