Samsung MZ-7KE256BW

Overview

The Samsung MZ-7KE256BW is a 256GB solid-state drive designed for installation in any system with a standard 2.5-inch SATA bay. It uses Samsung’s 3D V-NAND technology with 32 stacked memory layers to deliver sequential read speeds up to 550 MB/s and write speeds up to 520 MB/s. This SSD offers a significant performance boost over traditional mechanical drives and many earlier SSD models, making it suitable for faster boot times, quicker file transfers, and improved responsiveness in everyday computing tasks.

Key features

• 3D V-NAND architecture with 32 vertically stacked layers enhances storage density and reliability.
• Sequential read speeds up to 550 MB/s and write speeds up to 520 MB/s for smooth data access and transfer.
• Random read and write performance reaching up to 100,000 and 90,000 IOPS respectively, ideal for handling many small files efficiently.
• Hardware-based AES 256-bit encryption with full support for TCG Opal 2.0 and IEEE 1667 ensures strong data security without slowing down performance.
• RAPID mode leverages system memory as a cache to further accelerate everyday tasks and improve overall responsiveness.

Connectivity and compatibility

This SSD connects via a standard SATA III interface, ensuring compatibility with a wide range of desktops, laptops, and workstations that support 2.5-inch SATA drives. Its plug-and-play design makes it easy to upgrade existing systems without requiring additional adapters or special hardware.

Performance and reliability

The combination of 3D V-NAND technology and an LPDDR2 cache reduces power consumption while maintaining high-speed data access. The thermal guard feature helps prevent overheating during extended use, which is especially beneficial for gaming sessions or large file transfers. With a high endurance rating and a decade-long warranty, this drive is built to last through demanding workloads and daily use.

Ideal uses and environments

This SSD fits well in setups where faster boot times and quick file access are priorities, such as travel laptops, gaming rigs, and desktop workstations used for video editing or content creation. Its security features also make it a strong choice for business users who require hardware-level encryption without compromising speed. The low power mode benefits users who need to maximize battery life on portable devices.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
