    Sandisk Z400S 256GB 2.5inch SSD Product Description

    Sandisk Business Class Z400S 256GB 2.5" SSD

    Key Features

    The SanDisk Z400s is a cost effective SSD designed to replace HDDs in SATA SAS PCIe computing platforms. On par with HDD pricing, it can outperform HDDs by a factor of 20, while providing 5 times the reliability at 1/20th the power consumption. The Z400s is highly versatile and can accommodate a wide range of platforms with its variety of form factors and capacities. It is available in 2.5" 7mm cased, M.2 (2242 & 2280), and mSATA form factors with capacities from 32GB up to 256GB. (Note: M.2 2242 is only available up to 128GB)

    The Z400s has also been validated for use in several of the top OEM platforms in the industry, demonstrating its endurance and ability to sustain high-volume transactions. Its solid-state design means there are no moving parts, making it shock-resistant and much more reliable than traditional HDDs, which translates into lower total cost of ownership (TCO) and a better end-user experience.

    Low Power The Z400s utilizes breakthrough SanDisk technology that optimizes power consumption, making it one of the lowest power consuming SSDs at 30mW for average power. This increases the amount of usable hours per battery charge, which is essential for modern mobile devices.

    TCO SanDisk SSDs are more reliable than HDDs, which can improve total cost of ownership (TCO) by reducing downtime due to hard drive failures. They also offer lower latency and greater read/write speeds over traditional HDDs* , so users may experience a noticeable improvement in responsiveness. IT departments can extend the useful life of their PC inventory by upgrading the HDDs to the Z400s SSD, thus prolonging replacement cycles and maximizing asset value.
