SanDisk X400 128GB 2.5" SATA Internal SSD

The SanDisk SD8SB8U-128G-1122 is a 128GB solid state drive that gives notebooks a quick, reliable boost without adding bulk. It mounts in a 2.5 inch bay and uses a slim 7 mm housing, so it slips easily into most everyday laptops and newer thin models.

Because the drive connects over a SATA interface, your operating system, applications, and files load much faster than they would from a traditional hard drive. SanDisk’s nCache 2.0 technology keeps those speeds steady during demanding tasks such as light video editing, large file transfers, or heavy multitasking. The drive relies on high-endurance TLC flash, which helps it stand up to years of regular use.

If you spend long hours away from a power outlet, the X400’s low power draw helps stretch battery life, making it a practical upgrade for commuters, students, and frequent travelers. TCG OPAL 2.0 support is available for organizations and individuals who need an extra layer of hardware-based data security.

Whether you are breathing new life into an older laptop, building an affordable portable workstation, or simply replacing a failing hard drive, this SSD delivers responsive performance in a compact package.
