This article covers Samsung (サムスン) 870 EVO 500GB SATA 2.5インチ 内蔵型 ソリッドステートドライブ (SSD) (MZ-77E500).

Overview

The Samsung 870 EVO (MZ-77E500) is one of Samsung's best-selling SSD series, offering a balanced blend of performance, reliability, and affordability. This 500GB model uses the SATA 6Gb/s interface in a standard 2.5-inch form factor, delivering sequential read speeds up to 560 MB/s and write speeds up to 530 MB/s — essentially saturating the SATA III bandwidth. It's an ideal drop-in upgrade for older laptops and desktops still relying on mechanical hard drives. Powered by Samsung's in-house MKX controller and equipped with 512 MB of DDR4 DRAM cache, the 870 EVO leverages V-NAND (TLC) technology to achieve a rated endurance of 300 TBW (total bytes written). This translates to years of reliable everyday use under typical workloads. The drive's compatibility is virtually universal: any system with an available SATA port can use it, making it a hassle-free storage solution. Positioned as a mid-range SATA SSD, the 870 EVO competes directly with offerings like Crucial MX500. While it can't match NVMe speeds, it excels in scenarios where SATA is the only option or where low power consumption and proven reliability are paramount. For budget-conscious users building a secondary storage drive or upgrading an aging system, this SSD remains a top contender.

Compatibility Guide

Interface: SATA 6Gb/s (backward compatible with SATA 3Gb/s and 1.5Gb/s) Form Factor: 2.5-inch, 7mm thickness (fits most laptop bays; desktop use may require a mounting bracket for 3.5-inch bays) Power: SATA power connector; typical power consumption under 5W OS Support: Windows, macOS, Linux, and other major operating systems * Note: Ensure an available SATA port on your motherboard. If your motherboard supports NVMe M.2 slots, consider an NVMe drive for faster performance, but if only SATA ports are free, this drive is an excellent choice.

Product Info

Release Date: Early 2021 Warranty: 3 years (manufacturer) Sales Channels: , major electronics retailers, PC parts stores Market Positioning: Mid-range SATA SSD. The EVO series is Samsung's mainstream consumer line, balancing cost and performance. The 870 EVO updates the controller to MKX and uses the latest V-NAND, achieving near-max SATA speeds.

Best Use Cases

Upgrading an old laptop or desktop: If your machine has a SATA port but no NVMe support, the 870 EVO will drastically improve boot times and application loading. The 500GB capacity is sufficient for the OS, essential software, and some personal files. Secondary storage or game drive: For users who want a reliable, low-power secondary drive for games or media, the 870 EVO is a solid pick. SATA is more than adequate for game loading, and the drive's endurance ensures longevity. * Reliability-focused builds: Samsung's track record with V-NAND and DRAM cache SSDs is excellent. The 870 EVO is suited for users who prioritize data integrity and consistent performance over raw speed. ## Alternatives
Direct competitors include the Crucial MX500 500GB (CT500MX500SSD1). Both drives offer similar sequential read/write speeds (~560/510 MB/s for MX500). The MX500 uses Micron's 3D NAND and includes Dynamic Write Acceleration, but its TBW is lower at 180 TB. Price-wise, the MX500 is often slightly cheaper. The 870 EVO counter with higher endurance (300 TBW), a more refined controller, and Samsung Magician software for easy management. If you need maximum reliability and are okay paying a small premium, go with the 870 EVO. If you're strictly budget-focused, the MX500 is a worthy alternative.

Things to Consider

The 500GB capacity may fill up quickly if you install several modern AAA games or work with large media files. Consider upgrading to the 1TB variant if you expect significant storage needs. SATA III's bandwidth cap (~560 MB/s) means this drive will never outperform an NVMe SSD. For users who frequently transfer large files or run data-intensive applications, an NVMe drive like the Samsung 990 EVO Plus is a better investment. If your system already has an NVMe slot, using a SATA drive might be a missed opportunity for higher speeds. Reserve the SATA drive for secondary storage and use an NVMe drive as the primary boot drive for best performance. Pricing per gigabyte for SATA SSDs has been slightly higher than for entry-level NVMe drives in some regions. However, the 870 EVO's proven reliability and Samsung's support justify the cost for many users.
