Samsung 860 EVO 250GB SATA 2.5インチ 内蔵 SSD MZ-76E250B

This article covers Samsung 860 EVO 250GB SATA 2.5インチ 内蔵 SSD MZ-76E250B.

Overview

The Samsung 860 EVO 250GB SATA 2.5-inch Internal SSD (model MZ-76E250B/EC) is a well-established entry-level SATA SSD from Samsung's popular EVO series. It offers sequential read speeds up to 550MB/s and write speeds up to 520MB/s, effectively saturating the SATA III interface. With a 250GB capacity, it is an ideal choice for OS installation or upgrading an older laptop's storage, especially for budget-conscious users or secondary machines. This SSD utilizes Samsung's V-NAND 3-bit MLC (equivalent to TLC) technology paired with a proprietary controller and Intelligent TurboWrite technology, ensuring snappy performance for everyday file operations and application launches. It is also officially compatible with PlayStation 4, reducing game load times when replacing the internal HDD. In the market, the 860 EVO sits firmly in the entry-to-mid-range SATA SSD segment. While it cannot match NVMe speeds, its SATA connectivity offers broad compatibility and rock-solid stability. It is an excellent upgrade path for older laptops and desktops still running mechanical hard drives.

Compatibility Guide

The Samsung 860 EVO 250GB uses the standard 2.5-inch form factor with a 7mm thickness. It fits directly into most laptop and desktop 2.5-inch drive bays. Some ultra-thin laptops may require a 9.5mm bay, but the 7mm drive is compatible with the vast majority of systems. It uses a SATA 6Gbps (SATA III) interface and is backward compatible with SATA II and SATA I ports. However, connecting to a SATA II port will limit speeds to around 300MB/s, so a SATA III-capable motherboard or laptop is recommended for full performance. For desktop installation, you will need a SATA data cable and a SATA power cable from your PSU. For laptops, the drive mounts directly into the internal bay with screws. PlayStation 4 compatibility is officially confirmed, making it a drop-in upgrade for the console.

Product Info

The Samsung 860 EVO 250GB MZ-76E250B/EC was released in January 2018. Its price has dropped significantly since launch, currently available for around $50-60 USD or ¥5,000-6,000 JPY on Japan. It comes with a 5-year limited warranty or 150 TBW (Total Bytes Written), whichever comes first. Market positioning is entry-level. While slower than NVMe SSDs, its SATA versatility and low cost make it a compelling choice for users upgrading from HDDs. Key specs include sequential read 550MB/s, sequential write 520MB/s, random read up to 97,000 IOPS, and random write up to 88,000 IOPS. Power consumption is very low: approximately 0.045W at idle and 2.5W during active read/write, making it suitable for battery-powered laptops.

Best Use Cases

Users upgrading from an HDD: Replacing a traditional hard drive with this SSD dramatically improves OS boot times and application loading. It is ideal for budget builds. However, creative professionals handling large media files may find 250GB insufficient. Reviving an older laptop: If your laptop has a SATA interface, swapping the HDD for this SSD can breathe new life into it. But if your laptop has an NVMe slot, an NVMe SSD would be faster. PlayStation 4 storage upgrade: Officially compatible, it reduces game load times. Note that PS4 Pro uses a SATA II interface, so maximum speeds are not achieved. Secondary storage or file server: Low power consumption and high reliability make it suitable for always-on machines. For a primary drive in a high-performance PC, consider an NVMe SSD instead.

Things to Consider

The Samsung 860 EVO 250GB is a SATA drive, so it is significantly slower than NVMe SSDs. If you need fast large-file transfers or want to minimize game loading times in modern titles, an NVMe drive is a better choice. The 250GB capacity is adequate for the OS and essential applications, but it will fill up quickly if you install multiple games or store video editing projects. Competitors include the Crucial MX500 and Western Digital Blue series, which offer similar performance and pricing. The 860 EVO is known for its 5-year warranty and reliability, but its 150 TBW endurance rating is modest; heavy daily writers should monitor their usage. Note that this model may be discontinued, so availability could be limited to remaining stock. Always purchase from authorized retailers like Japan to avoid counterfeit or gray-market units. ## FAQ
Q: Is this SSD compatible with Windows 10 and Windows 11? A: Yes, the Samsung 860 EVO works perfectly with Windows 10 and Windows 11, as well as macOS and Linux. Ensure your system's SATA controller is set to AHCI mode in the BIOS before installing the OS. Q: Do I need special tools to replace my laptop's HDD with this SSD? A: Typically, a Phillips-head screwdriver (#0 or #1) is sufficient. Some laptops may require a specific tool to open the back cover. After physical installation, you will need to reinstall the OS or clone your existing drive. Samsung provides free Data
