This article covers Samsung 860 PRO 2.5"SATA III 1TB内蔵SSD（MZ-76P1T0BW）[カナダ版].

Overview

The Samsung 860 PRO is a high-end SATA SSD launched in early 2018, designed for users who prioritize endurance and consistent performance above all else. The 1TB model (MZ-76P1T0BW) uses a 2.5-inch 7mm form factor and is one of the few consumer SSDs still employing MLC (2-bit-per-cell) NAND flash, which offers significantly higher write endurance compared to TLC or QLC alternatives. With sequential read speeds up to 560MB/s and write speeds up to 530MB/s, it saturates the SATA III interface, delivering snappy responsiveness for everyday tasks and file transfers. The 1GB DRAM cache helps maintain low latency during random I/O operations. This drive is aimed at professionals—video editors, workstation users, and anyone running applications that generate heavy write loads over long periods. While more affordable TLC SSDs can handle most consumer workloads, the 860 PRO stands out for its near-industrial write durability and stable long-term performance.

Compatibility Guide

The 860 PRO uses a standard SATA 3.0 (6Gbps) interface and fits any 2.5-inch drive bay with a thickness of 7mm or more. It works with both desktop PCs and laptops equipped with a SATA port. Desktop PCs: Connect a SATA data cable and a SATA power cable directly to the drive. Ensure your motherboard has an available SATA port. Laptops: Replace an existing 2.5-inch SATA drive if the bay supports 7mm thickness. Some older laptops require 9.5mm drives and may need a spacer—check your manual. * Caveats: This is not an M.2 or NVMe drive. Do not use passive adapters to connect to an M.2 slot; they will not work properly. Always verify physical fit before purchase.

Product Info

The Samsung 860 PRO was released in January 2018 with an original MSRP around $350 for the 1TB model. Today it is sold as new old stock with fluctuating prices. It carries a 5-year limited warranty or until the TBW (Terabytes Written) limit is reached, whichever comes first. Positioned at the top of Samsung's consumer SATA lineup, the 860 PRO differentiates itself from the 860/870 EVO series by using MLC NAND. This gives it double the program/erase cycles per cell compared to TLC, making it ideal for write-intensive environments such as databases, caching, and video rendering. While SATA performance caps at ~560MB/s, the drive's real value lies in its consistency under sustained load. Capacity: 1TB NAND: Samsung 64-layer 3D MLC V-NAND Controller: Samsung MJX (Maru) DRAM Cache: 1024MB (1GB) Sequential Read: up to 560 MB/s Sequential Write: up to 530 MB/s Endurance: 600 TBW Endurance Estimate: ~1.6 years (assuming 1TB writes per day)

Best Use Cases

Write-heavy creative workloads: Video editors, 3D artists, and photographers who write large files repeatedly will benefit from the MLC's higher write endurance. TLC drives may exhaust their TBW faster under heavy daily use. NAS or server cache drives: The 860 PRO's reliability makes it a solid choice as a cache or log drive in 24/7 operating environments. Its power-loss protection is limited, but the NAND endurance helps prevent premature failure. Users who value peace of mind: If you want the most reliable SATA drive on the market for your OS or critical data and are willing to pay a premium, the 860 PRO delivers. It is less likely to slow down with age compared to TLC drives. Who should skip it: Gamers looking for the best value or anyone needing NVMe speeds. A cheaper TLC SATA SSD or a budget NVMe drive will offer better cost per gigabyte or much faster transfer rates.

Things to Consider

Despite its premium positioning, the 860 PRO is now a legacy product. The NAND technology is two generations old, and newer TLC-based SSDs like the Samsung 870 EVO offer similar TBW ratings at a lower price. The SATA interface also limits performance to ~560MB/s—far below modern NVMe drives that can reach 7,000MB/s. For most consumers, the 860 PRO is overkill. A TLC SSD like the Crucial MX500 or Samsung 870 EVO provides plenty of endurance for typical workloads, and the savings can be put toward a larger capacity or a faster NVMe drive. Only choose the 860 PRO if you absolutely need MLC's durability advantage in a write-intensive scenario. Also check your system's physical clearance. Laptop bays must support 7mm drives; otherwise the drive will not fit. For desktops, ensure you have a free SATA port and power connector. ## FAQ
Q: How does the 860 PRO compare to the 870 EVO? A: The main difference is NAND type: the 860 PRO uses MLC (2 bits per cell), while the 870 EVO uses TLC (3 bits per cell). MLC offers higher write endurance per cell, but in practice, the 870 EVO's advanced controller and firmware narrow the gap. The 870 EVO is cheaper and more widely available. Choose the 860 PRO for maximum write durability, and the 870 EVO for cost efficiency. Q: Can I use the 860 PRO in a laptop? A: Yes, if your laptop has a 2.5-inch SATA
