The Samsung 860 EVO 1TB (model MZ-76E1T0BCN) is a 2.5-inch SATA III solid state drive designed for client and workstation storage upgrades. It uses Samsung V-NAND 3-bit MLC (TLC) flash memory paired with the Samsung MJX controller and a 1 GB LPDDR4 cache buffer. The drive delivers sequential read speeds of up to 550 MB/s and sequential write speeds of up to 520 MB/s, with Intelligent TurboWrite technology to sustain write performance during large file transfers. It supports AES 256-bit full-disk encryption and TCG Opal 2.0, and carries a rated endurance of 600 TBW with a 5-year limited warranty. For commercial procurement teams sourcing SSDs for desktop and laptop fleet upgrades, the 860 EVO 1TB offers a standardized 7 mm 2.5-inch form factor compatible with most existing SATA-based systems. Note that the MZ-76E1T0BCN model number carries the CN regional suffix, indicating China-market packaging; buyers should verify warranty coverage with their regional Samsung support channel.

Note: The cache specification in the original parameter table lists 512 MB. Per Samsung's official 860 EVO datasheet, the 1 TB capacity model is equipped with 1 GB LPDDR4 cache; 512 MB applies to the 250 GB and 500 GB models. The table above is preserved as published on the source page.
The 860 EVO 1TB uses Samsung's 4th-generation V-NAND TLC (3-bit MLC) flash memory, which stacks memory cells vertically to increase density and reduce the physical footprint compared to planar NAND. The Samsung MJX controller manages flash translation layer operations, garbage collection, and wear leveling. Intelligent TurboWrite allocates a portion of the NAND as a high-speed write buffer, allowing the drive to sustain sequential write speeds closer to the 520 MB/s rated maximum during large file copies. The drive is rated for 600 terabytes written (TBW) and a mean time between failures (MTBF) of 1.5 million hours, backed by a 5-year limited warranty or 600 TBW, whichever comes first.
The 860 EVO supports AES 256-bit full-disk encryption in hardware (Class 0) and complies with the TCG Opal 2.0 specification. This enables enterprise deployment scenarios where disk-level encryption is required for data-at-rest protection, such as laptops handling customer data, financial records, or intellectual property. Hardware-based encryption does not consume host CPU resources, unlike software-only encryption solutions. IT administrators can manage encrypted drives through TCG Opal-compatible management tools.
The drive measures 100 × 69.85 × 6.8 mm and uses the standard 2.5-inch SATA III (6 Gb/s) interface, making it compatible with the majority of desktop PCs, laptops, and all-in-one systems that accept 7 mm or 9.5 mm 2.5-inch drives. It can directly replace existing 2.5-inch HDDs or older SATA SSDs without requiring adapter brackets in most cases. For commercial fleet upgrades, this form factor standardization simplifies SKU management across mixed hardware environments.
The 860 EVO 1TB is suited for replacing mechanical hard drives in enterprise desktop and laptop fleets. Migrating from HDD to SSD reduces system boot times, application launch latency, and file access delays, which can improve employee productivity across office workloads. The 1 TB capacity accommodates operating system installations, productivity software, and local user data storage.
For creative workstations running photo editing, basic video editing, and audio production software, the 860 EVO serves as a boot drive and application storage volume. Its stable sequential read and write performance supports loading large project files and exporting rendered media. For heavy 4K or 8K video production, a higher-end NVMe SSD is typically recommended; the 860 EVO is appropriate for entry-to-mid-level creative workloads.
In small business environments, the 860 EVO can be used as a read cache tier or frequently-accessed file storage in desktop workstations. Its hardware encryption support helps protect confidential documents, contracts, and customer data stored locally on employee machines. Note that this drive is a client-class SSD without power-loss protection (PLP) and is not firmware-optimized for 7×24 NAS operation; for network-attached storage deployments, buyers should select NAS-specific or enterprise SSD models.
The Samsung 860 EVO 1TB is backed by a 5-year limited warranty or 600 TBW (terabytes written), whichever limit is reached first. The MTBF is rated at 1.5 million hours.
Yes. The drive supports AES 256-bit full-disk encryption (Class 0) and is compliant with the TCG Opal 2.0 specification, enabling hardware-accelerated data-at-rest protection managed through compatible enterprise software.
It uses the SATA III (6 Gb/s) interface and a 2.5-inch form factor with a 7 mm height. It is compatible with most desktops, laptops, and all-in-one systems that accept 2.5-inch SATA drives.
The 860 EVO is a client-class SSD designed for desktop and laptop use. It does not include power-loss protection (PLP) or NAS-optimized firmware. For NAS or 7×24 server environments, enterprise or NAS-specific SSD models are recommended.
