This article covers Samsung 870 EVO 1TB SATA 2.5インチ 内蔵 SSD MZ-77E1T0B.

Overview

The Samsung 870 EVO 1TB is one of the most widely adopted SATA SSDs on the market, known for its consistent performance and reliability. Designated as model MZ-77E1T0B/EC, this 2.5-inch drive with a 7mm thickness fits into most desktop PCs, laptops, and even the PlayStation 4. It delivers sequential read speeds of up to 560MB/s and write speeds of 530MB/s, effectively saturating the SATA 3.0 interface. This SSD leverages Samsung's in-house controller and V-NAND 3-bit MLC (TLC) technology, ensuring stable long-term operation and high endurance. It comes with a 5-year warranty and a TBW rating of 600TB, making it suitable for daily use as an OS drive or data storage. As an officially warrantied product for Japan, users benefit from local language support and domestic repair services. Positioned as an entry-to-mid-range SATA SSD, the 870 EVO is a go-to choice for upgrading older systems or adding affordable bulk storage. While it cannot match NVMe speeds, it offers excellent value for SATA-based builds.

Compatibility Guide

The Samsung 870 EVO 1TB uses a SATA 3.0 (6Gbps) interface and is backward compatible with SATA 2.0 and 1.0. Its 2.5-inch, 7mm form factor fits most laptop drive bays, but desktop users may need a 3.5-inch mounting bracket for standard drive cages. It is officially verified for use with the PlayStation 4, allowing for faster load times when replacing the internal HDD. Note that this drive is not compatible with the PlayStation 5's internal storage slot, which requires M.2 NVMe SSDs. Additionally, ultra-thin laptops with only M.2 slots cannot accommodate this 2.5-inch drive.

Product Info

Released in 2021, the Samsung 870 EVO 1TB is a mature SATA SSD with a proven track record. Pricing typically falls around ¥10,000–¥12,000 in Japan, placing it in the standard range for 1TB SATA SSDs. The warranty covers 5 years or 600TBW, whichever comes first. In the market, it sits comfortably in the mid-range SATA segment. While not as fast as NVMe, it delivers top-tier performance for SATA-connected systems, thanks to Samsung's proprietary controller and V-NAND technology.

Best Use Cases

Users upgrading an older PC: If you are replacing a mechanical HDD in a system with only SATA ports, this SSD will dramatically improve boot times and application loading. It is a cost-effective way to breathe new life into aging hardware. Budget-conscious bulk storage seekers: For game libraries, media files, or backup drives, the 870 EVO offers a lower cost per gigabyte than NVMe SSDs. It is ideal for secondary storage where speed is less critical than capacity. * PlayStation 4 storage expansion: Officially verified for PS4, this drive reduces load times in games. However, the improvement is limited by the console's SATA 3.0 interface, so don't expect NVMe-like gains. ## Alternatives
A direct competitor is the Crucial MX500 1TB, which offers similar sequential speeds (560/510 MB/s) but a lower TBW of 360TB. The MX500 is often priced slightly lower, but the 870 EVO's higher endurance and Samsung's reputation for consistent performance give it an edge for long-term reliability. Another alternative is the Western Digital Blue SA510 1TB, with comparable specs (560/530 MB/s) but a TBW of 400TB and a shorter 3-year warranty. The WD Blue is typically cheaper, but the 870 EVO's longer warranty and higher TBW make it a better choice for heavy write workloads.

Things to Consider

The Samsung 870 EVO 1TB is limited by the SATA interface, which caps performance far below NVMe SSDs. For tasks involving large sequential file transfers, such as video editing or database work, an NVMe drive will be significantly faster. Additionally, this drive cannot be used in modern laptops that only have M.2 slots, so check your system's storage interface before purchasing. With a TBW of 600TB, the drive is rated for about 1.6TB of writes per day over 5 years. For typical home or office use, this is more than sufficient, but for write-intensive server applications, consider an enterprise-grade SSD. ## FAQ Q: Is this SSD compatible with Windows 11? A: Yes, it is fully compatible. The drive will be recognized as a standard SATA device, and Windows 11 can be installed on it. However, ensure your system meets other Windows 11 requirements like TPM 2.0 and Secure Boot. Q: Do I need special tools to install this in a PS4? A: You will need a Phillips-head screwdriver (#0 or #1) to remove the PS4's drive bay cover and mounting screws. The console does not include these tools, so have them ready. Q: What is the power consumption of this SSD? A: Idle power consumption is around 0.3W, while active read/write draws about 2.5W. This is significantly lower than a mechanical HDD, helping to extend battery life in laptops.
