This article covers Samsung (サムスン) 870 EVO 1TB SATA 2.5インチ 内蔵型 ソリッドステートドライブ (SSD) (MZ-77E1T0) [並行輸入品].

Overview

The Samsung 870 EVO 1TB (model MZ-77E1T0) is the latest addition to Samsung’s extremely popular EVO line of SATA SSDs. It delivers sequential read speeds of up to 560 MB/s and write speeds of up to 530 MB/s, pushing the SATA 6Gb/s interface to its practical limit. Equipped with Samsung’s V-NAND technology and an in-house MKX controller, this drive offers a substantial performance boost over traditional hard drives for everyday computing, gaming, and office tasks. While it cannot match the bandwidth of NVMe PCIe Gen4/Gen5 drives, the 870 EVO shines in systems that only support SATA connections—older laptops, budget desktops, or as a secondary storage drive for games and media. The included Samsung Magician software provides easy firmware updates, performance optimization, and data migration tools, adding to its value. Positioned as a mid-range SATA SSD, the 870 EVO is an excellent choice for users upgrading from an HDD or replacing an older SATA SSD. It balances cost, reliability, and performance better than any other SATA SSD on the market today.

Compatibility Guide

The Samsung 870 EVO 1TB is a 2.5-inch SATA SSD with a 7mm thickness. It is compatible with: Interface: SATA 6Gb/s (backward compatible with SATA 3Gb/s and 1.5Gb/s) Form Factor: Standard 2.5-inch drive bay (desktop bracket may be needed; laptop must support 7mm thickness) * Power: SATA power connector (desktop) or direct from laptop motherboard Most modern laptops and desktops accept 7mm drives, but some older machines may have a 9.5mm bay. In such cases, a 2.5mm spacer can be used or the drive can be mounted without issues. Ensure your system BIOS is set to AHCI mode for optimal performance, especially when installing the OS.

Product Info

Released in January 2021, the Samsung 870 EVO is the current flagship SATA SSD in Samsung’s EVO series. The 1TB model typically retails around $100–$130 (import price may be lower) and offers a 3-year limited warranty. Key specifications: Capacity: 1TB Interface: SATA 6Gb/s Form Factor: 2.5-inch (7mm) NAND: Samsung V-NAND 3-bit MLC (TLC) Controller: Samsung MKX DRAM Cache: 1GB LPDDR4 Sequential Read: up to 560 MB/s Sequential Write: up to 530 MB/s Random Read (4K QD32): up to 98,000 IOPS Random Write (4K QD32): up to 90,000 IOPS TBW: 600TB Warranty: 3 years limited Market positioning: mid-range. It is the best-performing SATA SSD available, but it is still a SATA drive—expect NVMe-like speeds only from NVMe drives.

Best Use Cases

  1. HDD-to-SSD upgrade for general users If you have an older laptop or desktop that still uses a mechanical hard drive, swapping it for the 870 EVO will dramatically improve boot times, application loading, and overall system responsiveness. It’s a straightforward upgrade that doesn’t require any special technical skills. 2. Secondary game storage for gamers Gamers who already use an NVMe drive for the OS and critical games can add this 1TB SATA SSD for storing a large library of lesser-played titles. Load times will be noticeably faster than an HDD, and the cost per gigabyte is attractive. 3. Reviving an old laptop Laptops with only a SATA port (no M.2 slot) can be given a new lease on life with this SSD. Whether as a replacement for the internal HDD or installed in the optical drive bay, the 870 EVO will make the machine feel much snappier. Who should NOT buy: Users who need maximum sequential throughput for professional video editing or large file transfers should invest in a PCIe 4.0/5.0 NVMe drive. Also, if your motherboard has a free M.2 slot, a comparable NVMe SSD offers better value for money.

Things to Consider

First, verify the model number on the packaging and ensure you are buying from a reputable seller. Import units may lack Japanese manuals and official Samsung warranty support. Always check the warranty policy before purchasing. SATA SSDs are inherently slower than NVMe, so do not expect to match the performance of modern PCIe 4.0/5.0 drives. If your system has an M.2 slot, you might be better off with an NVMe drive in the same price range. Compared to the DRAM-less Samsung 870 QVO (QLC), the 870 EVO offers better endurance (600TBW vs 360TBW for the 1TB QVO) and more consistent random performance. However, the QVO is cheaper and offers larger capacities up to 8TB. Choose according to your workload. ## FAQ
Q: What is the difference between the 870 EVO and 870 QVO? A: The 870 EVO uses TLC NAND with a DRAM cache, giving it better sustained write speeds, random performance, and endurance (TBW). The 870 QVO uses QLC NAND and is DRAM-less, which makes it more affordable for bulk storage but less suitable for heavy write workloads. Choose EVO for durability and performance; choose QVO for cheap, large-capacity storage. Q: Can I use this SSD in a PS4 or PS5? A: Yes, for PS4 you can replace the internal hard drive. For PS5, the internal exp
